What do I do about an adverse reaction to the yellow fever vaccine?


It dependson the severity of the reaction. Mild reactions do not need to be reported.

For mild reactions, such as:

  • soreness
  • redness
  • swelling where the shot was given
  • fever or aches

Take any over-the-counter analgesics, such as acetaminophen or a non-steroidal anti-inflammatory medication, such as ibuprofen.

For severe reactions, such as:

  • rash
  • hives
  • itching
  • difficulty breathing, tightness in the chest
  • swelling of the mouth, face, lips or tongue

Seek medical attention immediately or call 911. If you have a severe reaction, your doctor will want to know when you got the shot, symptoms and when they happened. Call the clinic that gave the shot and ask that they save any leftover vaccine and the vaccine bottle. Write down the vaccine lot number.
