Recommendations for vaccines are made globally for each flu season, but it’s important to note that there are actually two “flu seasons” in a year, the northern hemisphere and the southern (corresponding to winter in each). The recommendations are made every 6 months, so other parts of the world may have a different vaccine in the same calendar year.
