”Even the most effective vaccine only works if people trust it.”

Health Canada’s chief medical adviser Dr. Supriya Sharma’s reaction to concern raised by an American regulatory body about AstraZeneca’s clinical trial results for its COVID-19 vaccine.

Health Canada says the concern relates to the vaccine’s efficacy rate not to whether it’s safe.

Dr. Sharma says American questions about the efficacy rate change nothing for Canadians at this time.

”The press and the concerns around the AstraZeneca vaccine don’t help,” she adds.

Dr. Sharma says if there’s any change to the ”safety profile, if there is any significant change to how effective this vaccine is, we will take a look at that information” and share it with Canadians.
