Canadian Population Serological Survey Utilizing Antenatal Serum Samples
The objectives of the Canadian Population Serological Survey Utilizing Antenatal Serum Samples are to:
* Provide an immediate cross-sectional assessment of the seroprevalence of antibodies to SARS-CoV-2 in Canada.
* Assess the retrospective evolution of SARS-CoV-2 prevalence; antenatal serology can be assessed going back one year thereby providing an opportunity to go back to where 0% prevalence is detected.
* Plan to perform periodic future seroprevalence based on the level of seroprevalence on the first cross-sectional assessment.
* Compare seroprevalence between Canadian provinces and territories.
