Vaccine Side Effects

Are there side effects?

The most common side effect of getting a vaccine is pain where the shot was given. Other common side effects include:

  • Swelling and redness where the shot was given
  • Mild fever
  • Chills
  • Feeling tired
  • Headache
  • Joint and muscle pain

These side effects are a sign that the vaccine is working to build immunity and protection from the disease. Serious reactions can happen but they are very rare. For example, out of 1 million doses of a vaccine, 1 to 2 people may have a severe allergic reaction such as difficulty breathing, swelling of the face and throat, dizziness and weakness.

The autism connection?

Some parents worry that vaccines cause autism. Vaccine safety experts have concluded that the rubella vaccine, often cited as one cause of autism, is not responsible for increases in the number of children with autism.

Why does the autism myth persist? Signs of autism usually start to show around the same time that children would be getting the rubella vaccine. You can learn more by clicking here.
