Some countries do not recognize that people are fully vaccinated if they have received two different doses of the vaccine and will require them to self-quarantine upon entry. On Monday, the Quebec government announced it would offer an additional dose of an mRNA vaccine to people who want it for travel.
Dr. Joss Reimer, medical lead for the Manitoba Immunization Task Force, said she recognized that refusal to recognize mixed vaccine doses could be a barrier for some.
But there is no clear medical benefit to receiving a third dose, so Manitoba will not provide them, she said at a press conference on Wednesday.
She said she expects countries to likely start easing those restrictions as time goes by and begin to recognize mixed doses of vaccines.
“It makes sense to be cautious and very limited in eligibility when we just open things up for the first time,” she said.
“But as we all learn globally together, we expect that to change over time. “
Manitoba recently recommended that people receive the same vaccine for both doses when possible, but allowed people to mix the types of vaccines they receive in order to get more people vaccinated completely faster.
This spring, the province suspended administration of the first doses of the AstraZeneca-Oxford vaccine due to supply issues and concerns about blood clots. He reserved some of that vaccine for the second doses, but the province recommended the second doses of Pfizer-BioNTech or Moderna for those who received AstraZeneca first.
Reimer said the province would consider offering third doses of a COVID-19 vaccine if new evidence shows it has a clear benefit.
“In the absence of a clear benefit, we cannot recommend a third dose to individuals for whom we know there is a very low – but not zero – risk associated with each dose of the vaccine,” she said. declared.
But if more countries do not recognize mixed vaccines, “we will have to review and determine whether the risk to the individual can be worth it for the benefit of being able to travel.”
