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.
There are a large variety of flu vaccines so that even people with egg allergies, pregnant people, and people with chronic health conditions can get vaccinated with a vaccine that is appropriate for them.
Possible Side Effects
Some people do experience side effects with the flu vaccine. These generally resolve in a few hours or days. These side effects may include:
- Injection site reactions such as soreness, redness, and swollen arm
- Muscle Aches
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.
