Canada providing data to countries who do not accept mixed-dose travellers

The Public Health Agency of Canada says it’s working with other governments still uncertain about allowing Canadians with mixed vaccines to enter their countries.

The United States is one of multiple countries that only recognize people with two identical doses of an approved vaccine as being fully vaccinated. Oxford-AstraZeneca is not an approved vaccine in several places.

Chief public health officer Dr. Theresa Tam says the agency has provided data on the effectiveness of mixed doses to the U.S. and other top-priority destinations.

She says Canada has been spreading information about the effectiveness of mixing Oxford-AstraZeneca with m-R-N-A vaccines like Pfizer-BioNTech and Moderna.

At least 3.88 million fully vaccinated Canadians have received two different kinds of shots, not including those from Quebec where data on mixed vaccines is unavailable.

Of those, around 1.5 million Canadians received a first dose of Oxford-AstraZeneca or Covishield, which uses the same formula.
