I’ve been wondering if I should get the flu shot in Florida rather than the Canadian one since I spend most of the winter down there. Is there a difference?
We consulted with several medical professionals and learned that the flu shot is the same throughout North America – and indeed, in most Western countries. The flu strains that are covered in the shot each year are generally the same everywhere and the efficacy rate varies from year to year depending on how accurate the prediction was as to which strains would be dominant.
There is also an extra strength flu shot now that is recommended for seniors over 65.
While our research indicated that the flu shot is the same across North America, we still suggest you consult with your doctor on this point in case things change.
