“If the vaccines work, why are vaccinated people more likely to test positive?”
Recent raw data from Ontario makes it seem like the vaccines aren’t working. But as always, context matters.
a) Not everyone can get a test. Confirmed cases will tend to be those who are older, work in high-risk settings, and/or are more vulnerable. Those are all highly vaccinated populations.
b) The vaccines were rolled out to older and more vulnerable people first. So their immunity, which might have been lower to start with, will have waned more.
