Canada sharing data with countries who don’t accept mixed-dose travellers
OTTAWA — The Public Health Agency of Canada says it’s working with other governments still dubious about allowing Canadians with mixed vaccines to travel across their borders without quarantining.
Several countries, including the United States, only recognize people with two identical doses of an approved vaccine as being fully vaccinated.
Dr. Theresa Tam, Canada’s chief public health officer, says PHAC has presented data on the effectiveness of mixed doses to the U.S. and other top-priority destinations.
She says Canada has been particularly active in spreading information about the effectiveness of mixing Oxford-AstraZeneca with mRNA vaccines like Pfizer-BioNTech and Moderna.
