Types of Flu Vaccines

The virus that causes flu is constantly changing, so flu vaccines are updated each year to protect against the flu virus that is currently spreading.

There are many types of flu vaccines. Most types are given as a shot in the upper arm. The flu vaccine is also offered as a nasal spray, but the nasal spray is not recommended for people who are pregnant or people with a weakened immune system.

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.

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

Vaccine Updates for the 2023-2024 Flu Season

The best way to prevent flu and its potentially serious complications is by getting a flu vaccine every year.

  • Manufactured using virus grown in eggs.
  • Approved for use in children as young as 6 months.
  • Most flu shots are given in the arm (muscle) with a needle.

  • The flu vaccine is given as an intranasal spray.
  • The nasal spray flu vaccine is approved for use in healthy non-pregnant people, 2 through 49 years old. People who are pregnant and people with certain medical conditions should not get the nasal spray flu vaccine.

  • This flu shot is completely egg-free.
  • Approved for use in people 18 years and older.
  • This shot is made without flu viruses and contains three times the antigen (the part of the vaccine that helps your body build up protection against flu viruses) than other standard-dose inactivated flu vaccines, to help create a stronger immune response.

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
  • Fever
  • Muscle Aches
  • Headache
  • Fatigue

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.
