Influenza (Flu)

The best way to prevent the flu is to have a yearly flu vaccine. The seasonal flu shot protects against the three or four viruses that are predicted to be the most common for the upcoming flu season. The vaccine can change from one year to the next, which is why you must get the vaccine yearly.
