This week on Health Matters, Centre universitaire de santé McGill – McGill University Health Centre physician and researcher, Dr. Bruce Mazer discusses findings and unanswered questions about decoding immunity to COVID-19 and his role in the COVID-19 Immunity Task Force.
Dr. Mazer, Associate Scientific Director of the Taskforce, sums up the goal of their work as: to understand the prevalence of the virus in the community at large, and to learn about how the body responds to the virus. Completed studies in this area have revealed the following:
“We know that the prevalence of the antibodies in the population of healthy blood donors is between 0.7% and 1.0% of the population, as high as 2.9% in certain areas of Quebec and Ontario.”Dr. Bruce Mazer
Although these numbers indicate a lack of herd immunity, he feels it is more important to understand how to treat individuals who are most at risk, to develop a vaccine, and to find answers to some of their yet-to-be-answered questions. Finding answers to questions such as why some people are more affected by this virus than others, why some people are more affected by previous viruses but not this one, and how long the antibodies created by vaccination will last in the body, would go a long way in decoding immunity to COVID-19.
