Flu Shot FAQ
The flu shot is a vaccine that protects against some strains of seasonal influenza. Flu shots contain inactivated (dead) viruses, so they cannot give you the flu, says the Centers for Disease Control and Prevention. Flu shots are usually injected into the arm.

Who Needs a Flu Shot?
-
Almost everyone 6 months or older should get a flu shot, according to the Centers for Disease Control and Prevention (CDC). Flu shots are especially important for pregnant women, children under 2 years, health-care workers or caregivers, people older than 50, people in nursing homes and people with chronic medical conditions.
Are There Side Effects?
-
Some people experience soreness or redness at the injection site. A low-grade fever and aches also might occur. Severe reactions to flu shots are very rare, but if you experience a severe reaction, get immediate medical attention.

What if I Got a Flu Shot Last Year?
-
Because flu viruses constantly evolve, last year's flu shot probably won't protect you from this year's flu viruses. Getting a flu shot every year is the most effective way to avoid the flu.
Who Should Not Get a Flu Shot?
-
People with egg allergies or people who have experienced Guillain--Barré Syndrome after a flu vaccine should not get flu shots. In addition, if you have a fever, wait a few days to get your flu shot.
