Q&A: Understanding the Flu Vaccine

What Is the Flu Vaccine?

The flu vaccine is a yearly vaccine that protects against the most common types of influenza viruses. The goal of the vaccine is to reduce the risk of getting the flu and spreading it to others. It's recommended for most people, especially those at high risk of complications from the flu, such as older adults and individuals with chronic health conditions.

How Does the Flu Vaccine Work?

The flu vaccine stimulates your body's immune system to produce antibodies. These antibodies are what fight off the virus if you're exposed to the flu after getting vaccinated.

Does the Flu Vaccine Have Side Effects?

Like any medication, the flu vaccine can have side effects, but they are usually mild and short-lived. The most common side effects include soreness at the injection site, low-grade fever, and mild body aches.

Why Do I Need a Flu Vaccine Every Year?

Flu viruses evolve rapidly, and each year's flu vaccine is updated to include the most common strains expected to circulate. This is why it's recommended to get a flu vaccine every year.

Can the Flu Vaccine Give Me the Flu?

No, the flu vaccine cannot give you the flu. The vaccine contains killed or weakened viruses that can't cause illness.
