March 29, 2023
A newly released survey finds nearly all Canadian adults had antibodies against COVID-19 for about half of 2022, with most acquiring them through a previous infection.
The results, released Tuesday by Statistics Canada in partnership with the Public Health Agency of Canada and COVID-19 Immunity Task Force, show that 98.1 per cent of Canadian adults living in the country’s 10 provinces had antibodies against SARS-CoV-2, the virus that causes COVID-19, between April and August 2022.
These individuals acquired antibodies through either vaccination, previous infection or both.
Over that five-month period, 53.9 per cent developed antibodies through a past infection.
This is in comparison to the results of a previous version of the survey done between November 2020 and April 2021 that found 2.6 per cent of Canadians had COVID-19 antibodies due to a previous infection.
