Canadian study shows no significant association between COVID-19 vaccination and adverse peripartum outcomes

In a paper published in JAMA (Journal of the American Medical Association), CITF-funded researchers Drs. Deshayne Fell and Kumanan Wilson of the University of Ottawa and Dr. Jeffrey Kwong from the University of Toronto and colleagues found that COVID-19 vaccination was not significantly associated with an increased risk of adverse pregnancy outcomes.

Vaccine hesitancy among adults during Quebec’s COVID-19 vaccination campaign

Published in Frontiers in Public Health, the CARTaGENE research team, based at the Research Center at the Centre Hospitalier Universitaire Sainte-Justine and part of the CITF-funded CanPATH study, found that vaccination hesitancy among adults in Quebec was correlated with education levels, age and other socio-demographic determinants.

Dried blood spots can be a reliable test to detect SARS-CoV-2 antibodies

In a study now published in Microbiology Spectrum, a team of Vancouver investigators, led by Dr. Agatha Jassem of the British Columbia Center for Disease Control (BCCDC) and partially funded by the CITF, demonstrated that dried blood spot (DBS) testing should be considered reliable in detecting SARS-CoV-2 seropositivity acquired from both natural infection and vaccination.

Impact of Omicron wave apparent in Canadian Blood Services’ January data

Most Canadian blood donors exhibited some form of immunity against SARS-CoV-2 in January 2022, primarily due to vaccination. Nonetheless, infection-acquired seroprevalence increased sharply between December 2021 and the end of January 2022, nearly tripling from 6.4% to 16.3%. Almost a quarter of donors aged 17-24 were seropositive for infection-acquired antibodies (22.2%). Key findings: Nearly all blood donors (98.9%) tested positive for antibodies targeting the [...]

Blood data from early 2022 reflect Omicron’s impact prior to the holidays

In the first of a series of biweekly reports, the Canadian Blood Services revealed Omicron’s traction in December 2021. While all blood donors tested positive for the spike (S) protein, primarily due to immunization, infection-acquired seropositivity (as evidenced by anti-N IgG antibodies) climbed from 7.5% to 10.1 % from December 25, 2021 to January 15, 2022. This latter rate is roughly double the [...]
