The COVID-19 pandemic has exposed vulnerabilities faced by many populations, including the Two-Spirit, lesbian, gay, bisexual, transgender, queer, non-binary, and sexual minority (2SLGBTQ+) communities.
COVID-19 vaccine coverage continues to be lower among pregnant people than within the general Ontario population
The 6th report from the CITF-funded Better Outcomes Registry & Network (BORN) Ontario study that has not been peer-reviewed, led by Dr. Deshayne Fell (University of Ottawa), shows that 78% of pregnant individuals in Ontario had received one or more doses of COVID-19 vaccine before or during pregnancy by the end of September 2022.
A CITF-funded study published in Frontiers in Public Health and led by Dr. Nadine Kronfli (McGill University Health Centre) showed that correctional officers were most likely to have acquired SARS-CoV-2 but least likely to be vaccinated when compared to all other correctional workers, underscoring the importance of addressing both occupational risks and COVID-19 vaccine hesitancy to mitigate future outbreaks in the provincial prisons in Quebec.
Timely surveillance of respiratory syncytial virus (RSV) cases in children showed recent increased circulation
In a preprint, not yet peer-reviewed, CITF-funded researcher Dr. Pascal Lavoie (University of British Columbia) and colleagues found that children in British Columbia have been more vulnerable to respiratory syncytial virus (RSV) following a lull while protective measures were in place at the height of the COVID-19 pandemic.
A paper by Drs. Naveed Janjua and Zaeema Naveed (British Columbia Centre for Disease Control), and CITF-funded researchers from the Canadian Immunization Research Network (CIRN), including Dr. Jeff Kwong (University of Toronto), published a paper in the Journal of the American College of Cardiology that evaluated the odds of developing myocarditis or pericarditis as a result of receiving two doses of either the Pfizer or Moderna mRNA vaccines against COVID-19.
According to Canadian Blood Services, the infection-acquired antibody rate increased moderately from 65.4% in the last week of September to 66.3% by mid-October, consistent with the continued circulation of Omicron subvariants. Seroprevalence due to infection surpassed 80% among young donors (17-24 years of age) and 70% among the most materially deprived.
CITF-funded researchers at Héma-Québec, led by Drs. Marc Germain and Dr. Renée Bazin, published a preprint, not yet peer reviewed, reporting on the characteristics of the plasma donors whose samples are used to study COVID-19 immunity in Quebec.
In a CITF-funded study published in Culture, Health, and Sexuality, Dr. Daniel Grace (University of Toronto) and his team addressed how public health measures implemented during the COVID-19 pandemic impacted the sexual practices of gay, bisexual, queer, and other sexual minority men.
Héma-Québec estimates that 62% of adults in Quebec had been infected with the Omicron variant by the end of August 2022
Héma-Québec estimates that 62% of Quebecers who donated plasma had acquired antibodies following an infection with Omicron by the end of August 2022.
