Global Perspective

Seasonal influenza occurs in different months when comparing the northern and southern hemispheres. In the northern hemisphere, influenza occurs between the months of November and April, whereas in the southern hemisphere, the virus is most infectious between the months of June and October. Several factors are evaluated to determine the annual influenza vaccine composition including the influenza viruses that have circulated during the past year.
