However, the AZ vaccines have already been distributed in Canada and administered across the country.
From May 15, all people in the 50-54 age bracket, regardless of health, will be eligible for a vaccination.
Health Canada has put a hold on doses of the Johnson & Johnson COVID-19 vaccine that came into the country this week.
Health Canada is set to pause the first batch of 300,000 Johnson & Johnson Covid-19 jabs after learning that a part of the vaccine was made in the same USA plant where millions of doses were spoiled, the media reported.
Conservative health critic Michelle Rempel Garner said in question period Monday that NACI's advice is going to leave a lot of people confused about what vaccine to get - the first offered or the one they want.
The Danish weekly CPHPost quoted Professor Jan Pravsgaard Christensen from the Department of Immunology and Microbiology at the University of Copenhagen as saying that if only Pfizer and Moderna (the only vaccines allowed by Danish authorities) are to be applied, the last group "will have to wait until Christmas". It was paused after it emerged that there were six cases of vaccine-induced thrombotic thrombocytopenia in America.

"It is not yet clear whether the Janssen (Johnson & Johnson) Covid-19 vaccine is excreted in breast milk". The vaccine helps the body mount an immune response that will recognize and fight off a real SARS-CoV-2 virus if it is ever exposed to one.
But the rare blood clots associated with that vaccine are a "one in one million" event, Ellis said.
It also marks the latest hurdle for the single-dose vaccine, which has been long-awaited in hard-hit regions as a way to quickly immunize vulnerable populations.
