Vaccine Safety

All vaccines have to be tested to make sure they are both safe and effective. Vaccines, like any medication, can cause side effects. Even an aspirin can cause problems for some people; yet for most, it is safe and effective. The most common side effects of vaccines are mild pain, swelling and redness where the shot was given. Serious side effects from immunizations are extremely rare.

Although vaccines save thousands of lives each year, concerns about their safety continue. While no medicine or vaccine is without risk, the benefits far outweigh the risks. A decision not to immunize a child puts both the child and others who come into contact with him or her at risk of contracting a preventable disease that could be dangerous or deadly. Learn more:
