The second shot is advised to be given with Pfizer or Moderna. This is explained by the potentially better immune response from such mixed use.
For Canadians who received the first vaccination against the coronavirus with the AstraZeneca vaccine, local doctors advise that they do the second vaccination with Pfizer or Moderna. This is stated in the recommendations of Canada’s National Advisory Committee on Immunization (NACI), which advises the government on vaccination against COVID-19.
“The mRNA vaccine is now considered a priority for the second dose to people who received the first vaccine with the AstraZeneca / Covishield vaccine,” the agency said.
It is noted that this decision was made on the basis of “new evidence of a potentially better immune response from such mixed use.”
NACI also recognized both mRNA vaccines (Pfizer, Moderna) interchangeable.
“Individuals who received their first mRNA vaccine should be offered the same product for booster vaccination. If it is not available or unknown, a different mRNA vaccine should be used to complete the course,” the document says.
Due to the threat of side effects, all Canadian provinces have stopped using AstraZeneca for their first vaccine since early May, but continued to administer the second dose in some places.
According to the latest data, almost 70% of Canadians have already received at least one dose of COVID vaccine and about 15% have completed the full course.
It was previously reported that Australia bans AstraZeneca for people under the age of 60. The use of this drug causes thrombosis in 50-year-old patients.
