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 types of vaccines that can help you get protected from the flu. The most common type is an inactivated influenza vaccine, which contains killed virus particles. This type of vaccine works by stimulating your body's immune system to produce antibodies against the viruses in the vaccine. Another type of vaccine is a live-attenuated influenza vaccine, which contains weakened forms of the virus. This type of vaccine stimulates your body's natural defenses to produce antibodies against the virus. Both types of vaccines are safe and effective at preventing the flu.
