If you experience any of these serious side effects, seek medical attention immediately.
How to Reduce Side Effects
There are a few things you can do to reduce your risk of side effects from the flu vaccine:

- Take over-the-counter pain relievers, such as ibuprofen or acetaminophen, before and after getting the vaccine. This can help to reduce soreness and swelling at the injection site.
