Call your doctor at once if you have any of these serious side effects:
- fever, sore throat, and headache with a severe blistering, peeling, and red skin rash;
- fussiness, irritability, crying for an hour or longer;
- fast or pounding heartbeats; or
- easy bruising or bleeding.
Less serious side effects include:
- redness, pain, swelling, or a lump where the shot was given;
- headache, dizziness;
- low fever;
