Earlier this year, Canada’s National Advisory Committee on Immunization said it was safe to use some COVID-19 doses interchangeably in certain situations.
This meant COVID-19 vaccines from AstraZeneca, Pfizer-BioNTech and Moderna could be combined between first and second doses, where appropriate.
However, mixing and matching COVID-19 vaccines in this way hasn’t been approved in all countries just yet.
Earlier this week, Canadians planning vacations to Barbados raised concerns that the country did not consider people who received two doses of different vaccines to be “fully vaccinated.”
As vaccine mixtures were not seen as valid in Barbados, Canadian travellers who’d received mix and match doses did not qualify for any travel restriction exemptions there.
Royal Caribbean won’t accept mixed vaccines as being fully vaccinated

Holland America Line, Norwegian Cruise Line and Princess Cruises all modified their Health and Safety protocols to exclude those who had received mixed COVID-19 vaccinations, noting those who recieved AstraZeneca plus another vaccine would now be considered unvaccinated and unable to sail.
The move has left many Canadians and Brits who received mixed doses alongside AstraZeneca upon the recommendations of their home countries wondering what will happen to their cruises.
