Dr. Theresa Tam said robust vaccination rates have helped reduced hospitalizations and deaths but inoculations must rise further to avoid renewed strain on hospitals and the health-care system.
She urged younger adults to become fully vaccinated as soon as possible, saying they continue to lag among age groups but are associated with the highest rates of disease transmission.
About 6.3 million Canadians have not received a first dose and over 5 million have not had a second, Tam told a news briefing.
“With just over five weeks until Labor Day in Canada, this time is crucial for building up protection before we gather in schools, colleges, university and workplaces this fall,” she said.
Tam said vaccine coverage must be more than 80% in all age groups to establish better protection.
Current COVID-19 case counts have plummeted by 93% since the peak of the third wave, for an average of 640 new infections being reported daily over the past seven days, Tam said.
Deputy chief public health officer Howard Njoo said Canada’s robust vaccination rate means any uptick in infections would likely not correspond to a marked rise in deaths and hospitalizations.
He warned that millions of unvaccinated Canadians ``are really at risk of serious outcomes.”
