That is the same advice federal and provincial health officials have been giving Canadians since the first vaccines were approved in December. But it is in direct contrast to advice given Monday by the National Advisory Committee on Immunization.
NACI said the mRNA vaccines from Pfizer-BioNTech and Moderna are "preferred" because they don't carry the remote risk of a new blood-clotting syndrome.
The 16-member panel of doctors and other vaccine experts said that Canadians who aren't at high risk of COVID-19 may choose to turn down the offer of Oxford-AstraZeneca or Johnson & Johnson and wait until they can get an mRNA vaccine.
