Third and fourth vaccine doses help curb viral transmission and curtail the spread of COVID-19
Many Canadians wonder whether third and fourth doses of vaccine truly make a difference in protecting them against COVID-19 infection and reducing the risk of transmitting the virus to others.
Why is BA.2 important and what should Canadians do about it?
With the more contagious BA.2 fueling a spring wave, getting a vaccine booster protects Canadians against rising health risks
