What you may not know is that you have a choice when it comes to getting a flu vaccine: a 3-strain flu vaccine or a 4-strain vaccine. The 3-strain vaccine covers two type-A viruses and one type-B virus. The 4-strain vaccine may offer broader coverage from the flu by covering two type-A viruses and two type-B viruses.

Are there different forms of the flu vaccine?

Yes. There are multiple forms of flu vaccines, including the traditional "shot," intradermal, and the nasal spray form of the flu vaccine. In addition, there are vaccines that cover 3 strains of the flu and vaccines that cover 4 strains of the flu. The 4-strain flu vaccine may offer broader coverage by covering an additional strain.

Ask your pharmacist or healthcare provider if a 4-strain flu vaccine is right for you and your family.

Can the flu vaccine give you the flu?

You cannot catch the flu from the flu vaccine. The flu vaccines that are given by needle are made with viruses that are killed or virus proteins that are artificially made. The viruses used to develop the nasal spray flu vaccine are alive but weakened.

Are there side effects from the flu vaccine?

Some people experience mild side effects after getting the flu vaccine.

Some people experience mild side effects after getting the flu vaccine.Side effects may include:

Side effects may include:

  • Soreness, redness, or swelling where the vaccine was given
  • Fever (low grade)
  • Aches
  • Nausea

Side effects in adults that may occur with the nasal spray version of the vaccine include:

  • Runny nose
  • Headache
  • Sore throat
  • Cough

Who shouldn't get the flu vaccine?

Those who shouldn't get the flu vaccine include:

  • Children younger than 6 months of age and children younger than the age for which the vaccine is approved. Approved age ranges vary by vaccine
  • People who have had a severe allergic reaction to a flu vaccine in the past or people with egg allergies

You should talk to your doctor about whether the flu vaccine is right for you. Tell your doctor if:

  • You have a moderate-to-severe illness with or without a fever (you should wait until you recover to get vaccinated)
  • You have a history of Guillain-BarrĂ© Syndrome (a severe paralytic illness, also called GBS) that occurred after receiving a flu vaccine

The CDC recommends annual vaccination, but does not recommend which flu vaccine to get.

When is "flu season" in the US?

Influenza can occur at any time, but most influenza occurs from October through May.

When should I get my flu vaccine?

Getting the vaccine as soon as it is available can help protect you in the event flu season comes early in a particular year.

When does protection from the flu vaccine begin and how long will it last?

Once you get vaccinated, it takes about 2 weeks for protection to develop. The CDC recommends that you should receive a flu vaccine every year.
