I've heard that there is a vaccine that will protect me from getting the flu. Is this true?

Yes, it’s true. There are several different vaccines available for the seasonal flu, and they all work in slightly different ways. The most common one is called “TIV” (trivalent inactivated influenza virus vaccine). It contains three different types of flu viruses, which are designed to match the strains that are most likely to cause illness during the upcoming season.
