The study design and cohort profile of a CITF-funded study have been published in Epidemiology and Health. The research aimed to examine the prevalence and predictors of SARS-CoV-2 infection and transmission, as well as the predictors of the health and psychosocial impact of the COVID-19 pandemic, among Canadian children and their families.
A CITF-funded proof-of-principle study, published in the Journal of Infectious Diseases, found that high avidity anti-nucleocapsid (anti-N) IgG antibodies detect SARS-CoV-2 reinfections with higher specificity compared to solely measuring anti-N IgG serum levels.
A CITF-supported study, published in JAMA Network Open, systematically compared the clinical manifestations of different SARS-CoV-2 variants in the pediatric population presenting in emergency departments.
A CITF-funded study, published in BMC Infectious Diseases, aimed to determine age-specific population SARS-CoV-2 seropositivity and identify risk factors for infection among unvaccinated children and young adults.
A CITF-funded study, published in The American Journal of Clinical Nutrition, reported that SARS-CoV-2 infection and vaccination affected the antibodies found in human milk. This held despite the type of variant causing the infection and the vaccine dose interval.
A CITF-funded study, published in the Canadian Journal of Public Health, found that the frequency of on-time routine childhood vaccinations decreased during the first wave of the Covid-19 pandemic in Toronto.
A CITF-funded study, published in the Journal of the Pediatric Infectious Diseases Society, showed that specific antibody immune characteristics previously linked to more severe respiratory syncytial virus (RSV) infections waned among women of childbearing age in 2020-2021.
A CITF-funded study, published as a preprint and not yet peer-reviewed, found that the highest seropositivity rates among unvaccinated youth were among children under four years old and young adults aged 20-24.
The latest results from the CITF-funded EnCORE study, led by Dr. Kate Zinszer (Université de Montréal), looking at seroprevalence among children and adolescents in Montreal found that 79.4% of young children and teens had infection-acquired antibodies between February and June 2023.
A CITF-funded study, published in Influenza Other and Respiratory Viruses, found previously seronegative children were 9 to 12 times more likely to seroconvert due to infection during the early Omicron-dominant period (May to October 2022) than in pre-Omicron periods.
