The National Advisory Committee on Immunization of Canada has recommended “mixing and matching” of AstraZeneca, Pfizer and Moderna Covid-19 vaccines.

National Advisory Committee on Immunization Guidelines

They had issued guidelines for provinces and territories on mixing and matching 2nd doses of Covid-19 vaccines. It has advised Canadians to combine either “AstraZeneca-Oxford, Pfizer-BioNTech or Moderna shots” interchangeably for specific situations. NACI recommended it on the basis of early research from United Kingdom & Spain. Research highlights, mixing shots of AstraZeneca and Pfizer vaccines was safe and effective in preventing the disease. It recommended, first shot of AstraZeneca vaccine can be followed by shots of Moderna or Pfizer.

Why mixing-matching was recommended?

The Canadians who had a 1st dose of Moderna or Pfizer, they can now take any one of two shots as a 2nd dose. This is so, because both the vaccines were prepared with similar mRNA technology.
