Prime Minister Justin Trudeau says the only way Canada brings the pandemic to a close is for everyone to get vaccinated as soon as possible, amid a flurry of fear and frustration over new advice from the National Advisory Committee on Immunization.

NACI said Monday that Canadians who aren’t at high risk of COVID-19 may choose to wait until they can get a shot of either Pfizer-BioNTech or Moderna, because they don’t carry the remote risk of a new blood-clotting syndrome.

NACI said Canadians under 30 shouldn’t be offered AstraZeneca or Johnson & Johnson at all, because their risk of severe illness or death from COVID is outweighed by the potential risk of the syndrome known as vaccine-induced thrombotic thrombocytopenia, or VITT.

That directly contradicts long-standing advice from Health Canada to get the first vaccine you’re offered, and Trudeau said Tuesday that advice still stands.

“On a personal level, I am extremely pleased that I got the AstraZeneca vaccine a number of weeks ago,” he said.

“It was extremely important to me to be able to protect my loved ones, to protect my family and to do my part, to ensure that all Canadians get through this as quickly as possible. And that’s the reality. We all want to get through this pandemic as quickly as possible. And that means all of us getting vaccinated as quickly as possible.”

Chief Public Health Officer Dr. Theresa Tam said she understands that people may be frustrated or angry about changing advice but she said things change as science changes. She said there are different risk-benefit conclusions based on individual and community situations.

“But again, I’ll reiterate from our chief medical officers that the AstraZeneca vaccine deployed in the middle of a third wave has saved lives and prevented serious illnesses,” she said.

Some of the debate may not matter much. Canada is supposed to get up to 36 million doses of the mRNA vaccines in the next two months – 24.2 million Pfizer and between 10 million and 12 million from Moderna.

Comparatively, Procurement Minister Anita Anand said Tuesday there are only deliveries of about 1.6 million doses of AstraZeneca expected, though negotiations to get additional doses from a U.S. supply of that vaccine are ongoing.

There are no shipments of J&J even tentatively scheduled.

The first 300,000 doses of J&J arrived last week but are on hold because they were partly made at a Maryland facility with numerous safety violations. Health Canada is trying to verify the doses meet required standards.

Trudeau said Moderna’s next shipment of one million doses is now arriving in Canada Wednesday, a week ahead of schedule.

Canada expects to get 92 million doses of Pfizer and Moderna by the end of September, 18 million more than it needs to give two doses to every Canadian.
