Ontarians who received the first dose of the AstraZeneca vaccine and who have not yet received their second dose from the Ontario government to allow for the mixing of COVID-19 vaccines if desired.
“Nothing is more important than the health of Ontarians, and for the best protection against COVID-19 it is vital that everyone who received the AstraZeneca vaccine for their first dose receives the second dose of a COVID-19 vaccine.” “We are providing individuals who have received only their first dose of the AstraZeneca vaccine with two recommended options based on the available data and evidence and will continue to work with Health Canada to monitor the quality and efficacy of all COVID-19 vaccines being used in Ontario,” said Dr. Williams in a news release on June 3.
Beginning June 4, 2021, Ontarians who have received their first dose of the AstraZeneca COVID-19 vaccine have a choice to get a second dose of the AstraZeneca vaccine, or an mRNA (Pfizer or Moderna) vaccine provided at the recommended 12-week interval.

Ottawa/IBNS: Canada is changing its guidelines and will advise Canadians to combine either the AstraZeneca-Oxford, Pfizer-BioNTech, or Moderna shots interchangeably in certain situations.

The efficacy and safety of mixing and matching AstraZeneca and Pfizer vaccines in preventing COVID-19 are based on emerging research from Spain and the United Kingdom.
National Advisory Committee on Immunization (NACI)'s current guidelines states that a vaccination series that begins with AstraZeneca should follow up with the same shot and only recommends mRNA vaccines to be used interchangeably if the same first dose is unavailable.
Based on these findings, NACI would provide the updated guidelines to provinces and territories in the coming days.
These recommendations will impact Canada's vaccine rollout due to issues with the supply of AstraZeneca and a rare but serious type of blood clot that can result after the shot called vaccine-induced immune thrombotic thrombocytopenia (VITT).
NACI will recommend Canadians who have had the first dose of Moderna or Pfizer, to take either of the two shots as a second dose.
