Can vaccines cause side effects?

Question: 

Can vaccines cause side effects?

Answer: 
Yes. Like any medication or supplement (including vitamins), vaccines can cause side effects. 
 
  • Vaccine side effects are usually minor, such as a sore arm or mild fever, and go away within a few days.
  • Many people have no side effects at all.
  • Serious side effects are very rare.
  • The risks from the diseases that vaccines prevent are much greater than the risk of vaccine side effects.
