Physical distancing, mask-wearing could be in place for 2-3 years even with vaccine, Tam warns

Canadians shouldn’t expect a COVID-19 vaccine to be a “silver bullet” that will bring a swift end to the coronavirus pandemic and a return to normal, according to the country’s chief public health officer.

Dr. Theresa Tam used her briefing on Tuesday in Ottawa to temper expectations about the speed and effectiveness of a vaccine. She reiterated the importance of physical distancing, proper hand hygiene and mask-wearing, and attempted to dissuade any notion that a vaccine will make life go back to the way it was in a couple of months.

“We can’t at this stage just put all of our focus [on a vaccine] in the hopes that this is the silver bullet solution,” said Tam.

“We’re going to have to manage this pandemic certainly over the next year, but certainly [we are] planning for the longer term of the next two to three years during which the vaccine may play a role but we don’t know yet.”

Tam said it’s unclear at this stage how effective a vaccine will be. She said key questions remain about the degree and duration of immunity a vaccine will provide, the dosage that will be needed and whether it will prevent people from getting infected altogether or simply prevent severe illness requiring hospitalization.
