Since no one can accurately predict which, or how many, of the circulating influenza viruses will infect them, the trivalent seasonal influenza vaccine will provide the broadest protection.

This year, more than 10 000 influenza viruses from all continents were isolated and characterized by the WHO/National Influenza Centres.

Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to influenza outbreaks in humans.
