What are possible side effects of the intradermal flu vaccine?

In studies, common reactions to the intradermal flu shot included redness, swelling, toughness, pain, and itching at the injection site. With the exception of pain, these side effects were more common with the intradermal shot than they are with regular flu shots.

Other side effects included headache, muscle ache, and tiredness. These symptoms usually go away within 3 to 7 days.

While severe reactions are uncommon, you should let your doctor, nurse, clinic, or pharmacist know if you have a history of allergy or severe reaction to flu vaccine or any part of flu vaccine, including eggs.

The decision to give the intradermal vaccine should be based on the potential benefits and risks, especially if Guillain-Barré Syndrome has occurred within 6 weeks of receiving a prior flu vaccine.
