Question:
Do vaccines cause side effects?
Answer:
Vaccines, like any medicine or supplement (including vitamins), may cause some side effects. Vaccine side effects are generally mild, like soreness, redness, and swelling where the vaccine was given, or fever, and usually last 1 to 2 days. Serious side effects are very rare. The dangers of vaccine-preventable diseases are many times greater than the risks of a serious vaccine side effect.
