Canada needs to adopt a 'more sustainable' approach to COVID-19, Tam says

Canada's top doctor said today the country needs to find a more "sustainable" way to deal with the COVID-19 pandemic and future variants of the virus.

Speaking to reporters at the weekly public health briefing, Chief Public Health Officer Dr. Theresa Tam said all existing public health policies, including provincial vaccine passports, need to be "re-examined" in the coming weeks — because it's clear now that Canada and the rest of the world will be grappling with this virus for months or years to come.

"What we need to do going forward, as we emerge out of this Omicron wave, is recognize this virus is not going to disappear. We need to be able to address the ongoing presence of the SARS-CoV-2 virus in a more sustainable way," Tam said.

"Further waves will occur. Some will be quite severe and disruptive and we need to be ready for them. But we do need to have longer-term, sustained approaches and capacity-building so we're not in a crisis mode all the time as we fight this virus."

Tam said the Public Health Agency of Canada is talking to its provincial and territorial counterparts to chart a path forward for a country exhausted after two years of enduring some of the most restrictive measures in the developed world.

Together, she said, these agencies will review the current "suite of measures," including severe border restrictions and travel limitations.

"I think the whole concept is, we do need to get back to some normalcy," Tam said.

She said Canada's efforts should be focused on preventing severe cases of COVID through vaccinations rather than stopping all new infections of a highly transmissible virus.

Tam said it's now clear that the primary series of a COVID-19 vaccine — the first two shots of an mRNA vaccine or a viral vector product like the AstraZeneca vaccine — do not protect against an Omicron infection.

But these shots still offer "reasonably good protection" against severe outcomes like hospitalization and death. A third shot provides "superior protection," dramatically reducing the likelihood of severe outcomes, she said. A third dose might also help to prevent an actual infection, Tam added.

Tam said the country's priority should be to deploy as many booster shots as possible. But the immunization campaign has stalled, with just 50 per cent of people eligible for a booster having had that third shot. 

With vaccines widely available and promising therapeutics like Pfizer's Paxlovid starting to roll out, and with natural immunity levels higher in the wake of a massive wave of Omicron cases, Tam said she's "optimistic" that the country can find a better balance between fighting COVID and letting people return to more normal lives.

Dr. Howard Njoo, Canada's deputy chief public health officer, said Canada must guard against public health threats while "not unduly restricting travel and trade."

The top doctors' comments come after some European countries vowed this week to do away with many of the public health measures that have become fixtures of everyday life for the past two years.
