Types of Flu Vaccines

There are many types of flu vaccines, including shots and nasal sprays. All flu vaccines for the 2022-2023 season are quadrivalent vaccines, designed to protect against four different flu viruses, including two influenza A viruses and two influenza B viruses.

If you have questions about which vaccine is best for you, talk to your doctor or other health care professional.

In rare cases, a person should not get the flu shot. If you feel that you might fall into this category you should speak to your health care provider.
