Tracking health events after vaccination: latest results from CANVAS-COVID

Are you among the over 1 million Canadians asked to complete a survey after receiving the first or second dose of a COVID-19 vaccine? The CANVAS-COVID study, funded by the CITF/VSRG, has been collecting self-reported information on health events following vaccination. The most common health event following vaccination, experienced by 52% of participants enrolled, was temporary pain/swelling/redness at the site of injection.  The study [...]

Equity and design are key to successful vaccine passport programs in Canada

Commonly called vaccine passports, immunization records or documents indicating vaccination status will be important as certain parts of the world begin to reopen. Many Canadians see vaccine passports or vaccine certificates as a necessary step to re-enter public spaces and events; others are concerned that the need to disclose vaccine information may affect their rights. In a working paper published by the C.D. Howe [...]

Low prevalence of COVID-19 among Canadian dentists during the first wave

Dental care professionals are at high risk of SARS-CoV-2 exposure due to close contact with potentially infected patients and use of aerosol-generating procedures. A team of CIHR and CITF-funded scientists led by McGill University researcher Dr. Sreenath Madathil recently presented their results in two posters at the 99th General Session of the International Association for Dental Research (IADR). The preliminary results of their study [...]

Immunogenicity and safety of the Moderna vaccine in organ transplant recipients

Antibody levels, cell-mediated immunity, and safety were evaluated in solid organ transplant recipients who received two doses of the Moderna vaccine. Key findings from this study are as follows: 65.5% of patients had no detectable antibody (anti-RBD) response following the second vaccine dose; 73.1% were not able to neutralize the virus after the second dose; nevertheless, in a sub-study, nearly half of patients with [...]

The effects of preventive public health on children’s behaviours during the first wave of COVID-19

Dr. Jonathon Maguire and Dr. Catherine Birken from the CITF-funded TARGet Kids! collaboration in Ontario investigated the association between public health preventive measures related to COVID-19 and health behaviours and activities in children 10 years of age and younger. Recently published in the Canadian Journal of Public Health, the manuscript confirmed a reduction in children’s time outdoors and an increase in screen time during [...]

Social inequalities in COVID-19 vaccine acceptance and uptake for children and adolescents in Montreal

As part of their CITF-funded COVID-19 cohort study, Dr. Kate Zinszer and Dr. Caroline Quach, along with colleagues, examined whether parents from certain socioeconomic backgrounds or racialized groups were more – or less – inclined to have their child or adolescent vaccinated. In this preprint, not yet peer-reviewed, 87.6% of parents reported that their child was vaccinated or likely to be vaccinated against COVID-19. Researchers [...]

Vaccine effectiveness against the Gamma variant in a long-term care home in Ontario

An Ontario long-term care home (LTC) suffered a SARS-CoV-2 outbreak attributed to the Gamma variant. Researchers from a CITF-funded study led by Dr. Allison McGeer have published results in Clinical Infectious Diseases revealing that among the residents and staff considered to be part of the outbreak, 77% and 45% respectively, were fully vaccinated. The estimated vaccine effectiveness against any SARS-CoV-2 infection was 53.5% among [...]

Previous infection with common cold seasonal coronavirus may protect some from severe COVID-19

Nearly everyone has been exposed to the highly prevalent seasonal coronaviruses responsible for the common cold. But could this exposure induce antibodies that also recognize certain proteins of the SARS-CoV-2 virus? A CITF-funded study led by University of Ottawa researcher Dr. Marc-André Langlois, questioned if these antibodies could influence COVID-19 disease severity. In this pre-print, not yet peer reviewed, the team proposes that some [...]

CHILD Cohort COVID-19 Study’s rapid results

The CITF-funded CHILD Cohort COVID-19 Study regularly adds rapid results to its webpage. Information about the study’s participants is also included. The COVID part of their study is one-year long and is exploring: infections rates in children, why some children infected with the virus become seriously ill while others do not; risk factors for infection; and how physical distancing and school and business closures [...]
