When do most people get the flu?
Flu can occur at any time, but most influenza occurs from October through May. Getting vaccinated later in the season will still be beneficial, as long as the flu virus is still circulating.
Do you need more than one dose of flu vaccine?
Adults and older children need one dose of flu vaccine each year.
Children 6 months through 8 years getting a flu vaccine for the first time, will require two doses of vaccine for full protection. The first dose should be given as soon as the flu vaccine becomes available. The second dose should be administered 4 weeks after the first dose.
Can I get a flu shot and other vaccines at the same time?
Flu vaccine may be given at the same time as some other vaccines, including COVID-19 vaccines.
However, young children who get inactivated flu vaccine and pneumococcal vaccine (PCV13) at the same time appear to be at increased risk for seizures caused by fever. Ask your doctor for more information and tell your doctor if a child who is getting a flu vaccine has ever had a seizure.
If I have certain allergies, can I get a flu shot?
While allergic reactions to flu vaccines are rare, some people should not be vaccinated without first consulting a physician.
This year, an FDA Advisory Committee determined that people with an egg allergy may receive any flu vaccine (egg-based or non-egg based) that is appropriate for their age and health status. Additional safety measures are no longer recommended for receipt of any formulation.
Tell your doctor if you ever had a severe reaction after a flu shot. Tell your doctor if you ever had Guillain-Barré Syndrome (a severe paralytic illness, also called GBS). Your doctor will help you decide whether the vaccine is recommended for you.
People who are moderately or severely ill should usually wait until they recover before getting flu vaccine. If you are ill, talk to your doctor about whether to reschedule the vaccination. People with a mild illness can usually get the vaccine.
If you have questions about whether you should get a flu vaccine, consult your healthcare provider.
What are some of the symptoms I might experience after getting a flu shot?
A vaccine, like any medicine, could possibly cause serious problems, such as severe allergic reactions. However, the risk of a vaccine causing serious harm, or death, is extremely rare. You cannot get the flu from the vaccine. The safety of vaccines is always being monitored.
