Ground Report | New Delhi: Justin Trudeau got mixed dose: Canadian Prime Minister Justin Trudeau got his second dose of the COVID-19 vaccine. He got a shot of the Moderna vaccine to follow his first AstraZeneca shot. Mixing vaccine doses are currently allowed in Canada, but not approved in the US.
Justin Trudeau got mixed dose
Canada’s NACI updated its guidance at the beginning of June to recommend that people who got one dose of the AstraZeneca vaccine follow up with a second dose of either Moderna or Pfizer. Canadians are also allowed to mix and match Pfizer and Moderna. The shocking thing is that previously Canadian prime minister said that he will take the same vaccine shot, but he changed his decision at the time of vaccination and decided to get a mixed dosage of vaccines.
Still, the US Food and Drug Administration and Centers for Disease Control and Prevention have stood firmly against mixing vaccines. Researches have shown that combining different vaccines may trigger a stronger reaction than sticking to a single kind.
One research led by the Oxford University found that people who received a dose of AstraZeneca and a dose of Pfizer were more likely to have mild to moderate side effects compared to other vaccine recipients. Side effects tend to indicate a robust immune response, but the researchers have not yet released immunogenicity data for the mixed group.
Preliminary results from another research in Spain found that mixing doses successfully produced a boosted immune response. However, the researches have not yet been peer-reviewed, and those initial results were announced in an online presentation.
Survey by Abacus Data
In early June, the Canadian National Immunization Advisory Committee (NACI) gave people the green light to receive different vaccines for their first and second doses. NACI updated its guidance to say that the second injection of an mRNA vaccine, Moderna or Pfizer, can be a follow-up to the first dose of AstraZeneca. However, he added that if you received an injection of mRNA as the first dose, you should receive an injection of mRNA as the second injection.
The updated guide came after concerns were raised about the AstraZeneca vaccine and its possible link to rare blood clots. This change also came after there were concerns about the provision of AstraZeneca injections.
Just under 70 percent of Canada’s total population has received at least one dose of the COVID-19 vaccine and more than 30 percent have received two.
A recent survey by Abacus Data shows that doubts about vaccines in our country have dropped from nearly 40 percent in early March to a new low of just 16 percent.
