These details come in response to Jerome Goudreau’s story, which he reported yesterday Newspaper.

The Quebec man was forced to cancel plans for Caribbean cruises when he learned that the cruise line Norwegian Cruise Line did not consider his vaccine valid with Pfizer in the first dose and Moderna in the second.

“Exceptionally, people for whom it is necessary to receive an additional dose of the vaccine can receive it […] If the need to travel outside the country requires it and they initially received a mixed schedule,” says Noemi Vanhoferswen, a spokeswoman for the ministry.

Without special conditions

MSSS specifies that this dose can be given “to any person whose vaccination has not been recognized in the country to which he is going”.

People just have to make a ‘detailed’ appointment at Clic Santé or go for a ‘quick visit’.

However, some caveats are important. The additional dose is not required for protection and can lead to “more frequent and more severe” adverse reactions.

“It is up to everyone to weigh the risks and benefits,” the ministry recalls, in an email sent to magazine.

It is also not recommended to go to vaccination centers to get this extra dose in anticipation of a long-term trip because the situation is changing. Two levels of government confirmed Thursday that they were discussing access to internationally recognized mixed vaccines.
