The latest CITF-funded report from Canadian Blood Services suggested that seroprevalence due to infection was 80.1% among Canadian blood donors at the end of September 2023. This increased slightly from the 79.0% seroprevalence observed in August 2023.
A CITF-funded study, published in PLos One, found that among patients admitted to hospital who tested positive for SARS-CoV-2 during the Omicron wave, 52% had a primary diagnosis of COVID-19 and the others had incidental SARS-CoV-2 infections.
The latest CITF-funded report from Canadian Blood Services suggested that seroprevalence due to infection was 79.03% among Canadian blood donors in August 2023.
The latest CITF-funded report from Canadian Blood Services suggests that seroprevalence due to infection was stable at 80% among Canadian blood donors by the end of July.
A CITF-funded review, published in Campbell Systematic Reviews, found that among various strategies for promoting vaccine confidence, educational interventions were introduced to support individuals in their vaccine decisions by building COVID-19 vaccine knowledge and confidence. Group-based and formal presentations were the most frequently used.
The latest CITF-funded seroprevalence report from Canadian Blood Services shows that approximately 79.6% of adult blood donors had infection-acquired seroprevalence in May, which is similar to April (79.4%).
A CITF-funded study, published in Microbiology Spectrum, found that vaccinated donors, regardless of infection status, were more likely than unvaccinated donors to neutralize Omicron when assessed by a plaque reduction neutralization (PRNT50) assay.
The latest CITF-funded seroprevalence report from Canadian Blood Services showed that approximately 80% of adult blood donors had infection-acquired seroprevalence in April, which is slightly higher than in March (78.8%). Younger donors (ages 17-24) continued to have the highest seroprevalence compared to other age groups.
The latest CITF-funded seroprevalence report from Canadian Blood Services showed that infection-acquired seroprevalence among Canadian adult blood donors was stable between February and March (78.7% in March, compared to 77.6% in February).
Of the 62% of participants in a CanPath study who had infection-acquired antibodies, 86% had never suspected they had previously had COVID-19. These results from the CanPath SUPPORT-Canada study “Real-world insights on COVID-19 vaccine effectiveness and risk factors for COVID-19 infection” were made public during a hybrid event on May 30th.
