The vaccine then travels to lymph nodes, which are small glands that help produce antibodies. Mucosal tissues in the cervix and rectum present a unique challenge since the mucus in these areas can break down the vaccine quickly and wash it away, making it difficult to reach the lymph nodes and be effective.&nbsp;</p> <p>Aung’s research proposes fusing a protein carrier to the disease antigens, allowing it to reach distant mucosal lymph nodes after injection.&nbsp;&nbsp;</p> <p>“We aim to incorporate potent immunostimulatory components into our antigen construct, optimizing its distribution and enhancing mucosal antibody responses,” says Aung.&nbsp;&nbsp;</p> <p>“If successful, this work could lay the foundation for more effective vaccines that curb the spread of STIs, particularly in marginalized communities disproportionately affected by these diseases.”&nbsp;</p> <p>Aung’s&nbsp;project is one of <a href="/celebrates/51-faculty-members-receive-connaught-new-researcher-awards">51 Թϱ faculty members whose work is being supported by the Connaught New Researcher Awards</a> in the most recent round – and one of eight at Թϱ Engineering.

The number of children receiving routine vaccinations <a href="https://www.dlsph.utoronto.ca/2023/04/21/unicef-routine-childhood-immunization-report-2023-cvpd-shelly-bolotin/">has also&nbsp;dropped since the pandemic</a>.</p> <p>For the past few years, questions about vaccines dominated headlines and internet searches. Is this vaccine safe? Will it work? Who needs to get vaccinated?</p> <p><strong>Shaun Morris,</strong>&nbsp;a clinician scientist&nbsp;at The Hospital for Sick Children (SickKids) and an associate professor of pediatrics in the University of Toronto’s Temerty Faculty of Medicine, and&nbsp;<strong>Pierre-Philippe Piché-Renaud</strong>, who is pursuing a clinical and research fellowship at SickKids and graduate studies at Թϱ’s&nbsp;Dalla Lana School of Public Health,&nbsp;routinely field these types of questions from parents and caregivers.</p> <p>Both are members of the&nbsp;<a href="https://www.dlsph.utoronto.ca/institutes/centre-for-vaccine-preventable-diseases/">Centre for Vaccine Preventable Diseases</a> (CVPD)&nbsp;at the Dalla Lana School of Public Health.</p> <figure role="group" class="caption caption-drupal-media align-left"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/2024-01/morris-renaud_0.jpg" width="350" height="175" alt="&quot;&quot;"> </div> </div> <figcaption><em>Shaun Morris and Pierre-Philippe Piché-Renaud (supplied images)</em></figcaption> </figure> <p>To help boost confidence in vaccination through easy access to reliable, evidence-based information, Morris and Piché-Renaud have launched a new pilot project running until the end of March.&nbsp;</p> <p><a href="https://www.sickkids.ca/en/care-services/support-services/vaccine-consult-service/">The SickKids Vaccine Consult Service</a> (VCS), part of a larger project funded by the Public Health Agency of Canada (PHAC), is offering a phone service staffed by nurses to answer caregivers’ questions about all pediatric vaccinations. The intent is to make vaccine information more accessible and, ultimately, help parents make the best, most informed decision for their child, Piché-Renaud says.</p> <p>&nbsp;</p> <h4>Building on previous success</h4> <p>The pilot project builds off the success of a COVID-19-specific VCS phone line that ran from October 2021 to March 2023. The COVID-19 VCS received more than 2,700 calls from caregivers asking about COVID-19 vaccines for children. The phone line was staffed by health-care professionals who provided information tailored to each individual circumstance, including living situation or medical history – answers that could not typically be found on the internet.</p> <p>The nurses fielding calls were trained to create an open and safe environment, explains&nbsp;<strong>Julia Orkin</strong>, the SickKids COVID-19 VCS medical lead and an associate professor in Թϱ’s department of paediatrics in the Temerty Faculty of Medicine.</p> <p>“It wasn’t, you know, ‘you must do this,’ it was really a shared supportive conversation,” she says. After calling in, 83 per cent of caregivers surveyed said their questions and concerns were addressed, and more than 60 per cent said they would proceed with vaccination.</p> <p>The new phone service expands beyond the COVID-19 VCS by fielding questions not only about COVID-19 vaccines but all childhood immunizations. The service is open to anyone in Ontario, with a specific focus on patients with existing medical concerns and equity-deserving populations throughout the Greater Toronto Area.</p> <p>Insurance coverage and internet access aren’t required to book a VCS consultation and translation services are available.</p> <p>Piché-Renaud says that the conversations are about “taking it one step at a time, meeting parents where they are, and addressing their concerns.”</p> <p>Research has shown that COVID-19 vaccine uptake was&nbsp;lower&nbsp;among certain groups – for instance, certain racialized and lower income populations. To reach these communities, Morris and Piché-Renaud are working with organizations like&nbsp;<a href="https://www.bcchc.com/">Black Creek Community Health Centre</a>,&nbsp;<a href="https://www.taibuchc.ca/en/">Taibu Community Health Centre</a>&nbsp;and the Paediatric Alliance of Ontario.</p> <p>“The messaging is going to come through the people that [caregivers in these communities] already know and work with,” says Piché-Renaud.</p> <h4>Meeting an urgent need</h4> <p>Providing information on the importance of childhood vaccinations is particularly urgent.</p> <p>“Immunization coverage for a variety of diseases is lagging behind, leaving kids susceptible to infections and outbreaks that are completely preventable. It’s essential to provide parents with clear, individually tailored messaging from a trusted source to enable them to make informed decisions for their children,” says&nbsp;<strong>Shelly Bolotin</strong>, director of the Centre for Vaccine Preventable Diseases and an associate professor at the Dalla Lana School of Public Health.</p> <p>During the pandemic, routine childhood immunizations for preventable diseases like meningitis, measles and polio were set back to&nbsp;levels not seen since 2008. The proportion of Canadians who view vaccines as important for children also dropped from 91 to 82 per cent, according to&nbsp;<a href="https://www.unicef.org/reports/state-worlds-children-2023" target="_blank">UNICEF’s 2023 State of the World’s Children</a> report. Canada has since seen cases of&nbsp;pertussis (whooping cough)&nbsp;and&nbsp;other vaccine preventable diseases.</p> <p>“We’re still seeing kids who show up at SickKids and other paediatric hospitals with vaccine preventable illnesses, like certain types of meningitis,” says Piché-Renaud.</p> <p>The physicians hope that through the VCS phone line and a related project working with SickKids pediatricians and patients, they will be able to better understand why some children are not getting vaccinated. With this information, they can then develop resources such as educational websites, or improve access to vaccination sites.</p> <h4>Making trusted vaccine information more accessible</h4> <p>Morris and Piché-Renaud encourage Ontario parents wondering about childhood vaccines to <a href="https://www.sickkids.ca/en/care-services/support-services/vaccine-consult-service/">book a consultation appointment at SickKids VCS</a>.</p> <p>For Morris, empowering patients and families to make the best health decisions for themselves is one of the most important aspects of his job. Services like the VCS phone line help achieve that goal by “enabling people to connect to trusted sources of information and navigate through the quagmire of not good information, which is probably more common in the realm of immunization than in most areas.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 05 Feb 2024 14:18:11 +0000 Christopher.Sorensen 305803 at Breast milk may have protective effects against COVID-19: Researchers /news/breastmilk-may-have-potential-protective-effects-against-sars-cov-2-researchers <span class="field field--name-title field--type-string field--label-hidden">Breast milk may have protective effects against COVID-19: Researchers</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-01/IMG_7071-crop.jpg?h=e14f7e00&amp;itok=oTGbsM4T 370w, /sites/default/files/styles/news_banner_740/public/2024-01/IMG_7071-crop.jpg?h=e14f7e00&amp;itok=3fomH5it 740w, /sites/default/files/styles/news_banner_1110/public/2024-01/IMG_7071-crop.jpg?h=e14f7e00&amp;itok=q7SfWvdS 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-01/IMG_7071-crop.jpg?h=e14f7e00&amp;itok=oTGbsM4T" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-01-29T13:38:03-05:00" title="Monday, January 29, 2024 - 13:38" class="datetime">Mon, 01/29/2024 - 13:38</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>Samantha Ismail led a study by researchers at Թϱ and its partner hospitals that looked for SARS-CoV-2 antibodies in human breast milk (supplied image)</em></p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/betty-zou" hreflang="en">Betty Zou</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/covid-19" hreflang="en">COVID-19</a></div> <div class="field__item"><a href="/news/tags/emerging-and-pandemic-infections-consortium" hreflang="en">Emerging and Pandemic Infections Consortium</a></div> <div class="field__item"><a href="/news/tags/institutional-strategic-initiatives" hreflang="en">Institutional Strategic Initiatives</a></div> <div class="field__item"><a href="/news/tags/sinai-health" hreflang="en">Sinai Health</a></div> <div class="field__item"><a href="/news/tags/sunnybrook-health-sciences" hreflang="en">Sunnybrook Health Sciences</a></div> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/laboratory-medicine-and-pathobiology" hreflang="en">Laboratory Medicine and Pathobiology</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp;

I remember hoping that some of the protection I’d received from my vaccine would pass through to Elliott.”</p> <p>Now,&nbsp;new findings&nbsp;from a study led by researchers at the University of Toronto and its partner hospitals suggest that is the case.</p> <p><a href="https://ajcn.nutrition.org/article/S0002-9165(23)66182-9/fulltext#%20">Published in the <em>American Journal of Clinical Nutrition</em></a>, the study looked for antibodies against SARS-CoV-2 in breast milk from three different cohorts: individuals who contracted COVID-19 while pregnant or nursing, routine milk bank donors and individuals who received two doses of the COVID-19 vaccine while pregnant or nursing.</p> <p>The researchers detected antibodies in breast milk from roughly half of the people in the COVID-19 positive cohort.&nbsp;That’s compared to less than 5 per cent of routine milk bank donors, who did not have any known exposures to COVID-19. In the vaccinated cohort, they found that antibodies levels were higher in people who had received the Moderna vaccine compared to those who had received the Pfizer-BioNTech vaccine. Unexpectedly, people who had shorter intervals between their first and second doses had higher antibody levels than those who waited longer between their immunizations.</p> <p>“That finding definitely surprised me,” says&nbsp;<strong>Samantha Ismail</strong>, the study’s first author who completed her master’s degree in the lab of&nbsp;<strong>Deborah O’Connor</strong>, the Earle W. McHenry Professor and chair of Temerty Medicine’s department of&nbsp;nutritional sciences. “In [blood] serum, it’s the other way around where longer intervals between doses typically result in higher antibody levels, suggesting that something different is happening in this lactating population.”</p> <p>In addition to Ismail and<strong>&nbsp;</strong>O’Connor, the study was led by&nbsp;<strong>Sharon Unger</strong>, medical director of the&nbsp;<a href="https://www.milkbankontario.ca/">Roger Hixon Ontario Human Milk Bank</a> at Sinai Health and a Թϱ professor of medicine and nutritional sciences, and&nbsp;<strong>Susan Poutanen</strong>, microbiologist and infectious disease consultant and Sinai Health and Թϱ associate professor of laboratory medicine and pathobiology.</p> <p>The team took the study one step further by showing that some breast milk samples could prevent SARS-CoV-2 from infecting cells in a lab setting. Within the COVID-19 positive cohort, milk that contained antibodies against the virus were more likely to be neutralizing and immunization with the Moderna vaccine was associated with a stronger neutralizing capacity than the Pfizer-BioNTech vaccine.</p> <p>The researchers also found a small but significant number of breast milk samples that prevented SARS-CoV-2 infection despite having undetectable levels of antibodies, suggesting that there could be other components in human milk that are active against SARS-CoV-2.</p> <p>While these findings provide strong evidence to support the potential protective effects of human milk, Ismail cautions that the study alone is not enough to prove that breast milk provides tangible protection against COVID-19.</p> <p>“COVID-19 vaccination and infection result in antibodies in human milk that have neutralizing capacity, but we don’t know for sure how the neutralizing capacity seen in the lab translates to protection in infants,” says Ismail, who is now a second-year medical student at Թϱ.</p> <p>She points out that previous studies have shown a clear protective effect of antibodies in human milk against other viruses like enterovirus and rotavirus. To date, such studies have not been done with COVID-19.</p> <p>Even so, the findings provide reassuring news to parents like Doyle, who breastfed her son longer than she had intended to ensure that he was still getting breast milk when she received her second COVID-19 vaccine.</p> <p>“Trying to figure out how to protect this tiny being in that scary and bleak time, I was grasping at every little piece of information and whatever little piece of hope we had.”</p> <p>The study was supported by the Canadian Institutes for Health Research and was a collaboration between the department of microbiology at Sinai Health System/University Health Network, the Roger Hixon Ontario Human Milk Bank at Sinai Health System and the&nbsp;Toronto High Containment Facility, where the live SARS-CoV-2 neutralization studies were completed.</p> <p>It involved contributions from several members of the <a href="https://epic.utoronto.ca/">Emerging and Pandemic Infections Consortium</a>, a <a href="https://isi.utoronto.ca/">Թϱ institutional strategic initiative</a>.

Additionally, study results show that intramuscular administration of mRNA formulated with this nanoparticle caused potent cellular immune responses, even with limited expression observed in lymph nodes.</p> <p>“Our study showcases for the first time that mRNA lipid nanoparticles can still effectively stimulate a cellular immune response and produce robust anti-tumor effects, even without direct targeting or transfecting lymph nodes,” said Li.</p> <p>“This finding challenges conventional understandings and suggests that high transfection efficiency in immune cells may not be the only path to developing effective mRNA vaccines for cancer.”</p> <p>Lipid nanoparticles, also called LNPs, are crucial for delivering mRNA-based therapies including COVID-19 mRNA vaccines that were used worldwide during the recent pandemic. However, many LNP designs can inadvertently result in substantial mRNA expression in off-target tissues and organs like the liver or heart, resulting in often treatable but unwanted side effects. The drive to improve the safety of mRNA therapies that have the potential to treat a broad range of diseases means there is an urgent need for LNPs designed to minimize these off-target effects, explains Li, <a href="https://www.pharmacy.utoronto.ca/news-announcements/bowen-li-receives-2022-gairdner-early-career-investigator-award">a recent recipient of the&nbsp;Gairdner Early Career Investigator Award</a>.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-12/Li-lab-2023-11-crop.jpg?itok=a3lDHgji" width="750" height="500" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>From left to right: researchers Jingan Chen, Bowen Li and Yue Xu (photo by Steve Southon)</em></figcaption> </figure> <p>The new research shows that, compared to the current benchmark LNP developed by the Massachusetts-based biotechnology company Moderna, iso-A11B5C1 demonstrated a high level of muscle-specific mRNA delivery efficiency. It also triggered a different kind of immune response than what is seen in vaccines used to treat infectious diseases.</p> <p>“Interestingly, iso-A11B5C1 triggered a lower humoral immune response, typically central to current antibody-focused vaccines, but still elicited a comparable cellular immune response. This finding led our team to further explore this as a potential cancer vaccine candidate in a melanoma model, where cellular immunity plays a pivotal role,” Li said.</p> <p>The interdisciplinary research team that conducted the study includes&nbsp;<strong>Jingan Chen</strong>, a PhD trainee from the&nbsp;Institute of Biomedical Engineering, and&nbsp;<strong>Yue Xu</strong>, a postdoctoral researcher in the Li lab and a research fellow associated with&nbsp;<a href="https://www.prime.utoronto.ca/">PRiME</a>, a Թϱ <a href="https://isi.utoronto.ca/">institutional strategic initiative</a>.</p> <p>“Although iso-A11B5C1 showed limited capacity to trigger humoral immunity, it effectively initiated cellular immune responses through intramuscular injection,” said Chen. “The substantial anti-tumor effects observed with iso-A11B5C1 underscore its promise as a viable candidate for cancer vaccine development.” &nbsp;</p> <h4>New platform allows for faster, more precise lipid design</h4> <p>The research team identified iso-A11B5C1 by using an advanced platform developed to quickly create a range of chemically diverse lipids for further testing. This platform, newly introduced as part of the study, overcomes several challenges by streamlining the process of creating ionizable lipids that have a high potential to be translated into therapies.</p> <p>By rapidly combining three different functional groups, hundreds to thousands of chemically diverse ionizable lipids can be synthesized within 12 hours.</p> <p>“Here we report a powerful strategy to synthesize ionizable liquids in a one-step chemical reaction,” said Xu. “This new platform provides new insights that could help guide lipid design and evaluation processes going forward and allows the field to tackle challenges in RNA delivery with a new level of speed, precision and insight.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 15 Dec 2023 20:01:28 +0000 Christopher.Sorensen 304961 at Researchers partner with Moderna to develop new mRNA-based therapies for HIV and other diseases /news/researchers-partner-moderna-develop-new-mrna-based-therapies-hiv-and-other-diseases <span class="field field--name-title field--type-string field--label-hidden">Researchers partner with Moderna to develop new mRNA-based therapies for HIV and other diseases</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-07/GettyImages-vial-main.jpg?h=afdc3185&amp;itok=eRbwd8UV 370w, /sites/default/files/styles/news_banner_740/public/2023-07/GettyImages-vial-main.jpg?h=afdc3185&amp;itok=dTtOXMYH 740w, /sites/default/files/styles/news_banner_1110/public/2023-07/GettyImages-vial-main.jpg?h=afdc3185&amp;itok=J3Q8QJ0M 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-07/GettyImages-vial-main.jpg?h=afdc3185&amp;itok=eRbwd8UV" alt="Close-up of a needle drawing vaccine from a bottle"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>siddiq22</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-07-26T15:19:09-04:00" title="Wednesday, July 26, 2023 - 15:19" class="datetime">Wed, 07/26/2023 - 15:19</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>(Photo by Amornrat Phuchom/iStock/Getty Images Plus)</em></p> </div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/taxonomy/term/6906" hreflang="en">EPIC</a></div> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/chemistry" hreflang="en">Chemistry</a></div> <div class="field__item"><a href="/news/tags/partnerships" hreflang="en">partnerships</a></div> <div class="field__item"><a href="/news/tags/pharmacology" hreflang="en">Pharmacology</a></div> <div class="field__item"><a href="/news/tags/vaccines" hreflang="en">Vaccines</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">Projects will develop mRNA vaccines to treat HIV infection and technologies to modulate the body's immune response<br> </div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Two teams of researchers at the University of Toronto have partnered with Moderna Canada to advance new mRNA-based therapies for HIV and other diseases.</p> <p>The projects&nbsp;– one led by&nbsp;<a href="https://lmp.utoronto.ca/faculty/mario-ostrowski"><strong>Mario Ostrowski</strong></a>, an infectious disease physician at Unity Health Toronto and a professor of medicine, immunology and pathobiology and lab medicine at the Temerty Faculty of Medicine;

While these therapies help people with HIV live longer, they can also lead to side effects that negatively impact a person’s overall physical and mental health.</p> <p>To tackle this challenge, the researchers will design mRNA vaccines that are tailored to the unique strain of HIV found in each person. Ostrowski believes that these highly targeted vaccines can activate powerful immune cells to seek out and eliminate hidden viral reservoirs. Similar approaches have been used successfully to create personalized therapeutic vaccines for people with cancer.</p> <p>This work will also leverage the capabilities of the <a href="/news/u-t-receives-35-million-modernize-high-containment-facility">Toronto High Containment Facility</a> (THCF), which is equipped to allow researchers to study high-risk pathogens, such as HIV and SARS-CoV-2, in a safe and secure way. The facility is a cornerstone of the&nbsp;<a href="https://epic.utoronto.ca/">Emerging and Pandemic Infections Consortium</a>&nbsp;(EPIC)&nbsp;<a href="https://isi.utoronto.ca/">institutional strategic initiative</a>, a partnership between Թϱ and five major Toronto hospitals to advance innovative infectious disease research and strengthen preparedness for future pandemics.</p> <p>Containing the only containment level 3 (CL3) research lab in the Greater Toronto Area and the largest in the province, the THCF plays a critical role in supporting Ontario’s life sciences research ecosystem. Its unique infrastructure and capabilities enable cutting-edge research on vaccines and therapeutics and provide training opportunities needed to drive innovation and biomanufacturing in Ontario.</p> <p>Modulating the body’s immune response is also at the core of the project led by&nbsp;Cui&nbsp;and&nbsp;Edgar.</p> <p>Their work focuses on the sugars that coat the outside of all immune cells. These sugars, called glycans, have recently been shown to play an important role in fine-tuning the function of some immune system components. However, designing targeted and effective therapies to modulate the glycans themselves has remained elusive.</p> <p>In collaboration with Moderna, Cui and Edgar will develop mRNA technologies that can be used to adjust glycan levels within specific tissues&nbsp;– or even on specific cell types. If successful, this approach could be used to alter how immune cells function in a myriad of diseases.</p> <p>Through this cross-faculty and cross-sector collaboration, Cui and Edgar’s work would demonstrate the feasibility of using these cutting-edge technologies to manipulate the architecture of a cell’s surface and to improve immune responses through cell-surface engineering.</p> <p>“At Moderna, we are focused on the creation of transformative mRNA medicines. For the past 13 years, we have been investing in research and innovation into different facets of mRNA science,” says&nbsp;Patricia Gauthier, Moderna Canada president and general manager.</p> <p>“Our collaboration with the University of Toronto and its exceptional scientists further strengthens our resolve to push the boundaries of what can be achieved in this rapidly evolving field to improve the lives of patients through mRNA science.”</p> <p>As part of the partnership, each team will be paired with a scientific expert at Moderna who can champion their research and provide support and feedback.</p> <p>The selection of these two projects follows the announcement in October 2022 of a partnership between Moderna and a team of Թϱ researchers led by&nbsp;<a href="https://bme.utoronto.ca/faculty-research/core-faculty/omar-khan/"><strong>Omar F.

Despite more than 60 years of research, options for protecting vulnerable populations (such as newborns) against the virus remained limited – until now.</p> <p>Currently, the only option for protecting newborns at the highest risk of hospitalization (those born very prematurely, born with heart or lung conditions, or those born in remote communities without quick access to medical care) is a monoclonal antibody therapy called palivizumab. The drug cannot treat RSV, but if injected every month during RSV season, it can help prevent severe illness.</p> <p>However, palivizumab comes with a high price tag and needs to be administered every month – sometimes for up to six months – so it is typically reserved for high-risk infants. Health Canada recently approved a longer-acting antibody-based drug, nirsevimab, which would only require one injection per RSV season. Nirsevimab is expected to cost much less than palivizumab, and it may eventually be an option for all parents.</p> <p>A vaccine for pregnant people to help protect newborns from infection is also in the pipeline and may be approved as soon as later this year. The vaccine, recently approved in the U.S. for older adults, offers the prospect of protection against RSV infection – not just disease – to all newborns for the first time.</p> <p>This RSV vaccine, made by Pfizer and known as RSVpreF, would be given to individuals in their late second or third trimester of pregnancy. The vaccine prompts the pregnant person to makes antibodies that are transferred to their fetus, so their child is born with some protection against RSV. In a worldwide, double-blind clinical trial with pregnant women published in&nbsp;<a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2216480"><em>The New England Journal of Medicine</em></a>, the RSVpreF vaccine was more than 81 per cent effective at protecting infants against serious health issues caused by RSV, like lower respiratory tract illness.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-07/Human_Respiratory_Syncytial_Virus_%28RSV%29_%2833114415716%29-crop_0.jpg?itok=b_6QdFMT" width="750" height="500" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>Health Canada is on the verge of approving a new drug and a vaccine to protect children from respiratory syncytial virus (RSV), shown here in an electron micrograph image (image by NIAID)</em></figcaption> </figure> <h4>Speaking with parents about RSV and vaccination</h4> <p>In advance of the rollout of nirsevimab and Health Canada’s consideration of RSVpreF data, Fitzpatrick is listening to parents and learning about their understanding of RSV and potential concerns. Her research will involve conducting interviews with parents across Canada and using the information to create tailored educational materials that address questions and provide the information parents may need as they consider their future RSV immunization options.</p> <p>“We need to start planning now to make sure that parents are anticipating this, and they have the information they need to be able to make that decision,” she says.</p> <p>In addition to surveys and interviews, Fitzpatrick and her collaborators will be engaging with populations more vulnerable to RSV. For instance, research indicates that certain living conditions can play a role in a child’s risk for RSV.</p> <p>“We know if a child is exposed to mould, or if they live in a crowded house, they’re much more likely to catch any respiratory virus and for it to become a much more severe disease,” Fitzpatrick says.</p> <p>Specific regions and demographics are also disproportionately impacted by RSV. Collaborators on Fitzpatrick’s study will focus on parents in Nunavut – an area that has the highest rates of RSV hospitalization in the world.</p> <p>“They’re going to be working with community partners there to understand the unique barriers and motivators for RSV immunization in Inuit communities,” she says.</p> <p>Fitzpatrick is aiming to have the educational materials from her study available in time for next year’s RSV season, when nirsevimab and vaccines for pregnant people will hopefully both be available.</p> <p>“I hope this research provides parents with the information that they need to make the decision that’s right for them,” she says, noting that as a public-health practitioner, she ultimately hopes people decide to get immunized “so we can prevent as much RSV disease as possible.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 19 Jul 2023 18:50:09 +0000 siddiq22 302309 at Derrick Rossi, the stem cell scientist who co-founded Moderna, receives honorary degree /news/derrick-rossi-stem-cell-scientist-who-co-founded-moderna-receives-honorary-degree <span class="field field--name-title field--type-string field--label-hidden">Derrick Rossi, the stem cell scientist who co-founded Moderna, receives honorary degree</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-06-09T16:04:37-04:00" title="Friday, June 9, 2023 -

He attended Dr. Norman Bethune High School in Scarborough, where he says a science class instilled in him a passion for molecular biology. “As soon as I learned about molecular biology that was it, I knew what I wanted to be,” <a href="https://nationalpost.com/news/canada/heroes-of-the-pandemic-meet-the-canadian-hockey-dad-behind-covid-19-vaccine-developer-moderna">he told the <em>National Post</em> in 2020</a>.</p> <p>He went on to earn two degrees in molecular genetics at Թϱ, then a PhD from the University of Helsinki. He did a post-doc at Stanford University, and in 2007 was appointed assistant professor at Harvard University, where he ran his own lab.</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-06/DZ6_1633-crop.jpg?itok=1YXTWI9C" width="750" height="500" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>From left: Dalla Lana School of Public Health Dean Adalsteinn Brown, Derrick Rossi, Chancellor Rose Patten and President Meric Gertler (photo by Lisa Sakulensky)</em></figcaption> </figure> <p>Rossi’s research focused on stem cells. In particular, he was interested in determining whether he could modify the messenger RNA molecules to relay genetic code to human cells. “Genes and mutations in genes underlie pretty much all human genetic diseases, which is a large fraction of human diseases,” Rossi said in the interview with Թϱ.</p> <p>He realized that if you could “reprogram” a cell to bypass bad genes and mutations, then you could, in theory, treat a large range of genetic disorders, from Parkinson’s disease to sickle cell anemia and more.</p> <p>Rossi initially didn’t expect the discovery to serve as a platform for a new kind of vaccine. The reason was financial, not scientific: vaccines are generally not very profitable. “It’s not something that a biotech company would be thinking about because there’s not much money to be made there,” he told Թϱ.</p> <p>The exception, it turns out, is a global pandemic.</p> <p>Having undergone a career transition in 2010 from scientist to scientist-entrepreneur, Rossi says his research became increasingly focused on real-world applications. “As a biologist in a lab, you can answer a question that’s really interesting but isn’t going to move the needle on patient health at all,” he told Թϱ. “Or you can ask a different question that, if you get an answer to it, might solve a [patient’s] problem.</p> <p>“As soon as I realized that, pretty much all the questions we asked in my lab had that type of focus.”</p> <p>He notes that co-founding Moderna gave him the entrepreneurial “bug.” Since leaving the company in 2014 (he is still an investor), he has co-founded four other biotech startups: Intellia Therapeutics, which uses the genome editing technology CRISPR/Cas9 to create novel medicines for genetic diseases; Magenta Therapeutics, which is developing ways to use stem cell transplants to reset patients’ immune systems to cure autoimmune and other diseases; Stelexis Therapeutics, which focuses on the discovery of drug targets for cancerous stem cells: and Convalo Therapeutics, which has identified promising drug targets for treating neurological disorders.</p> <p>Rossi, who retired from Harvard in 2018, is a recipient of the Princess of Asturias Award for scientific research – an honour previously conferred on Stephen Hawking and AI pioneer and Թϱ <a href="https://www.provost.utoronto.ca/awards-funding/university-professors/">University Professor</a> Emeritus Geoffrey Hinton. He serves as a mentor at the Rotman School of Management’s <a href="https://creativedestructionlab.com/">Creative Destruction Lab</a> and conducts many media interviews in an effort to expand public knowledge about vaccine efficacy and safety. In 2011, <em>Time</em> magazine named Rossi one of the world’s 100 most influential people.</p> <p>In his convocation address today to graduate students in social work and public health, Rossi urges them to choose the road less travelled. “And if there isn’t a road there? That’s even better. Grab a machete and whack your way through the jungle of life, forging your own path. By doing so, you will maximize your life experience by colouring it in hues and pigments that you didn’t even know existed ... this is also a great strategy to prepare oneself for whatever may come your way in the future.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 09 Jun 2023 20:04:37 +0000 Christopher.Sorensen 301959 at Research shows how boosting immune memory could help develop improved flu vaccine /news/research-shows-how-boosting-immune-memory-could-help-develop-improved-flu-vaccine <span class="field field--name-title field--type-string field--label-hidden">Research shows how boosting immune memory could help develop improved flu vaccine</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-05/YeungKaren-crop_0.jpeg?h=afdc3185&amp;itok=UE518pJm 370w, /sites/default/files/styles/news_banner_740/public/2023-05/YeungKaren-crop_0.jpeg?h=afdc3185&amp;itok=4k1uMyW_ 740w, /sites/default/files/styles/news_banner_1110/public/2023-05/YeungKaren-crop_0.jpeg?h=afdc3185&amp;itok=_NJoB-D4 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-05/YeungKaren-crop_0.jpeg?h=afdc3185&amp;itok=UE518pJm" alt="Karen Yeung"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>siddiq22</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-05-11T16:33:55-04:00" title="Thursday, May 11, 2023 - 16:33" class="datetime">Thu, 05/11/2023 - 16:33</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p>PhD student Karen Yeung is one of the recipients of the inaugural EPIC Doctoral Awards for her work on boosting immune memory to enhance protection against influenza (supplied photo)</p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/betty-zou" hreflang="en">Betty Zou</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/emerging-and-pandemic-infections-consortium" hreflang="en">Emerging and Pandemic Infections Consortium</a></div> <div class="field__item"><a href="/taxonomy/term/6906" hreflang="en">EPIC</a></div> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/awards" hreflang="en">Awards</a></div> <div class="field__item"><a href="/news/tags/graduate-students" hreflang="en">Graduate Students</a></div> <div class="field__item"><a href="/news/tags/immunology" hreflang="en">Immunology</a></div> <div class="field__item"><a href="/news/tags/public-health" hreflang="en">Public Health</a></div> <div class="field__item"><a href="/news/tags/research" hreflang="en">Research</a></div> <div class="field__item"><a href="/news/tags/vaccines" hreflang="en">Vaccines</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Karen Yeung</strong>&nbsp;is no stranger to outbreaks of respiratory infections. As a child growing up in Hong Kong, she&nbsp;lived through the first SARS outbreak&nbsp;in 2003 and witnessed the city dealing with repeated threats of bird flu in the years that followed.</p> <p>Twenty years later, in the midst of a global pandemic caused by SARS-CoV-2, the&nbsp;fourth-year PhD student in the&nbsp;<a href="https://immunology.utoronto.ca/" role="link">department of immunology</a>&nbsp;at the University of Toronto's&nbsp;<a href="https://temertymedicine.utoronto.ca/" role="link">Temerty Faculty of Medicine</a>&nbsp;is leading critical research to understand how our immune systems respond to influenza infection –&nbsp;and how we might be able to leverage that knowledge to create a long-lasting, universal flu vaccine.</p> <p>Yeung is one of&nbsp;<a href="https://epic.utoronto.ca/research/funded-initiatives/results-of-the-2023-doctoral-awards-competition/" role="link">31 recipients of the inaugural Emerging and Pandemic Infections Consortium (EPIC) Doctoral Awards</a>, which supports outstanding students pursuing infectious disease research.</p> <p style="margin-bottom:11px">“Current flu vaccines work by inducing an antibody response against a specific component of the influenza virus, but this viral component mutates very quickly every year. This means that the antibodies that you make against this year’s flu vaccine likely won’t match the strain of flu that we’ll see next season,” says Yeung, who is supervised by <strong>Tania Watts</strong>, a professor of immunology at Թϱ who holds the Canada Research Chair in anti-viral immunity.</p> <p style="margin-bottom:11px">Immune cells called memory CD8+ T cells might hold the key to unlocking broad protection against multiple flu strains. These immune cells retain a memory of a pathogen long after the initial infection, which allows the body to quickly mount a powerful immune response the next time it encounters that pathogen. And unlike the antibodies generated from a flu vaccine, memory T cells recognize parts of the influenza virus that are more likely to remain unchanged between strains and from one year to another.</p> <p style="margin-bottom:11px">Previous work from Watts’ lab was the first to show that a protein receptor on CD8+ T cells called 4-1BB is an important player in the formation of memory T cells after a flu infection. 4-1BB is part of a communications cascade that relays cues to regulate the immune system. Yeung’s doctoral research aims to uncover how this pathway is turned on to produce memory CD8+ T cells.</p> <p style="margin-bottom:11px">“We’re really interested in how cells can communicate to each other through the language of receptors like 4-1BB and signaling,” Yeung says.</p> <p style="margin-bottom:11px">“When you have a lung infection due to flu, what kinds of signals are the CD8+ T cells receiving in the lungs that are helping them transition to memory T cells? How can we manipulate these mechanisms to form more of these memory cells?”</p> <p style="margin-bottom:11px">So far Yeung’s work points to monocytes – a type of immune cell that is recruited to the lungs early on during an infection – as providing the activating signal to allow more CD8+ T cells to become memory cells. Next, she’ll be looking at what happens during a secondary flu infection if 4-1BB signaling is disrupted and there are fewer protective memory T cells.</p> <p style="margin-bottom:11px">By deepening the understanding of how immune memory develops, Yeung’s research – which is funded by the Canadian Institutes for Health Research – is laying the groundwork for new approaches that could complement existing flu vaccine strategies to elicit a broader and longer-lasting immune response.</p> <p style="margin-bottom:11px">“It takes us closer towards a universal flu vaccine strategy, where one shot will be enough to protect against seasonal influenza and future influenza pandemics as well.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 11 May 2023 20:33:55 +0000 siddiq22 301624 at With $3-million chair, Թϱ and GSK focus on enhancing pharmacist-led vaccine care /news/3-million-chair-u-t-and-gsk-focus-enhancing-pharmacist-led-vaccine-care <span class="field field--name-title field--type-string field--label-hidden">With $3-million chair, Թϱ and GSK focus on enhancing pharmacist-led vaccine care</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-05/vaccination-gsk-stock-crop.jpeg?h=afdc3185&amp;itok=jhXalt99 370w, /sites/default/files/styles/news_banner_740/public/2023-05/vaccination-gsk-stock-crop.jpeg?h=afdc3185&amp;itok=xYwLEtUx 740w, /sites/default/files/styles/news_banner_1110/public/2023-05/vaccination-gsk-stock-crop.jpeg?h=afdc3185&amp;itok=-svVW4jP 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-05/vaccination-gsk-stock-crop.jpeg?h=afdc3185&amp;itok=jhXalt99" alt="child gets a band aid on their arm after receiving a vaccination"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-05-10T12:57:15-04:00" title="Wednesday, May 10, 2023 - 12:57" class="datetime">Wed, 05/10/2023 - 12:57</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p>(photo by Prostock Studio)</p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/kate-richards" hreflang="en">Kate Richards</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/leslie-dan-faculty-pharmacy" hreflang="en">Leslie Dan Faculty of Pharmacy</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp;

As the impact of the pandemic continues to stretch our health system, pharmacists are taking on an increased role in primary care, filling care gaps with pharmacy clinic services that include vaccinations. “But we need to ensure pharmacists are continually supported with evidenced-based tools to provide the best possible care over time,” Dolovich said.</p> <p>As a result of limited access and other barriers brought on during the height of the pandemic, many children and adults are behind on routine immunizations.</p> <p>A 2022 survey led by Campaign Research showed that one in five Ontario adults missed or delayed their routine immunization for preventable illnesses like shingles and pneumonia. Pharmacy teams can help address gaps in care like this and have demonstrated the ability to be nimble enough to implement new, innovative ways of providing critical health services.</p> <p>“Further supporting and enhancing the role of pharmacists as vaccine-care providers expands access for patients and helps support the health of our families and communities,” said Dolovich. “The creation of this chair provides an exciting opportunity to focus on how pharmacists can continue to play an important role in managing vaccine-preventable diseases.”</p> <p>The Leslie Dan Faculty of Pharmacy will soon begin recruitment for the chair through an open call for applications and submissions outlining proposed research programs that will drive the vision and impact of this initiative forward.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 10 May 2023 16:57:15 +0000 Christopher.Sorensen 301621 at Flu, COVID-19 and more: Leslie Dan Faculty of Pharmacy expert on the importance of getting vaccinated /news/flu-covid-19-and-more-leslie-dan-faculty-pharmacy-expert-importance-getting-vaccinated <span class="field field--name-title field--type-string field--label-hidden">Flu, COVID-19 and more: Leslie Dan Faculty of Pharmacy expert on the importance of getting vaccinated</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/UofT90189_2022-11-09-Cheryl-Vaccination-%2812%29-crop.jpg?h=afdc3185&amp;itok=TcKqM3WS 370w, /sites/default/files/styles/news_banner_740/public/UofT90189_2022-11-09-Cheryl-Vaccination-%2812%29-crop.jpg?h=afdc3185&amp;itok=LeiBilg2 740w, /sites/default/files/styles/news_banner_1110/public/UofT90189_2022-11-09-Cheryl-Vaccination-%2812%29-crop.jpg?h=afdc3185&amp;itok=LQJsKdr8 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/UofT90189_2022-11-09-Cheryl-Vaccination-%2812%29-crop.jpg?h=afdc3185&amp;itok=TcKqM3WS" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2022-11-21T11:12:21-05:00" title="Monday, November 21, 2022 -

We also know about the immense strain facing our emergency departments, hospitals and health-care system at the moment.&nbsp;</p> <p>In addition to wearing masks indoors, washing our hands and staying home when we are sick, getting vaccinated is the best thing we can do to protect ourselves and our community, and to lessen the burden on the health-care system.</p> <p><b>Can you get both shots at once?</b>&nbsp;</p> <p>Yes, anyone age five and over can safely get their flu and COVID-19 vaccines on the same day. Most of us should get both a flu vaccine and booster of the bivalent COVID-19 vaccine this fall. You are eligible for a fall booster of COVID-19 vaccine if it has been at least 3 months since your last booster or COVID infection.&nbsp;&nbsp;&nbsp;</p> <p><b>Can you remind us how these vaccines work?&nbsp;&nbsp;</b></p> <p>Vaccines help protect us from severe infections by imitating the virus so that if we get the infection, our body is ready to recognize it quickly and mount the immune response needed to fight it off.&nbsp; &nbsp;<b>&nbsp;</b></p> <p><b>What does it meant to stay “up to date” with vaccinations?</b>&nbsp;</p> <p>This means you are getting&nbsp;all the vaccines that are recommended, considering your age and personal circumstances – including risk factors and other medical conditions.&nbsp;This includes being up to date on other vaccines, such as tetanus and those recommended when we are children.</p> <p><img alt src="/sites/default/files/UofT90196_2022-11-09-Cheryl%20Vaccination-Zaijah%20Thomas-PharmD%202Candidate-lpr_0.jpg" style="width: 750px; height: 500px;"></p> <p><em>Zaijah Thomas prepares a dose of the flu vaccine at the Discovery Pharmacy clinic located on the St. George Campus (photo by Johnny Guatto)</em></p> <p><b>How should someone deal with anxiety or fear about getting vaccinated?&nbsp;</b></p> <p>This is important. This is often due to one of two reasons: one is being nervous about needles,&nbsp;which&nbsp;is more common than people think;&nbsp;the second is that some people are sometimes&nbsp;afraid when they don’t have enough information.&nbsp;</p> <p>For either reason, this can mean they don’t end up getting vaccinated or become stressed during vaccination. If they are stressed during vaccination, this increases their risk of experiencing adverse reactions, such as dizziness and fainting.&nbsp;</p> <p>The good news is we have ways to help.&nbsp;We use the&nbsp;<a href="https://www.aboutkidshealth.ca/card">CARD</a> (Comfort-Ask-Relax-Distract) system to invite people to ask questions and share their preferences for how they receive their vaccine.&nbsp;Within each letter category, there are different strategies to address concerns about vaccination.</p> <p>Here are a few examples: For&nbsp;“Comfort” people may want a private vaccination area or to bring a support person; for “Ask,” they may want to ask questions about the vaccine, or how to make the needle hurt less;&nbsp;to “Relax” while getting a vaccine, they can try deep breaths; and&nbsp;they may choose to&nbsp;“Distract” themselves with their cell phone, by playing with fidget toys or by looking away during injection.</p> <p>Speak to the person administering your vaccine about how the CARD system can help.</p> <p>&nbsp;</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 21 Nov 2022 16:12:21 +0000 Christopher.Sorensen 178270 at
