Canadian Population Serological Survey
Utilizing Antenatal Serum Samples

In Canada, there are limited data so far to inform the serological prevalence of SARS-CoV-2 antibodies in the population. This national project will improve our understanding of the seroprevalence of antibodies to SARS-CoV-2 through the use of antenatal blood samples. Anonymous seroprevalence studies using left over blood from samples routinely taken as part of prenatal care permits broad population level surveillance. Pregnant women are representative of generally healthy adults from ages 18-45 years from all socioeconomic and cultural backgrounds; in this way, use of these existing samples will provide a window into the generally healthy adult population of Canada as a whole. Findings from this project will inform the Canadian public health response to the COVID-19 pandemic.
