Vaccines are developed in order to prevent disease and keep people healthy. To achieve that purpose, they have to be safe and effective.
No medicine is without risk. However, vaccines have proven their effectiveness and tolerability over decades in use with billions of people of all ages around the world.
Vaccines are extensively studied in clinical trials and carefully evaluated by authorities before they are allowed on the market. Once on the market, safety monitoring by authorities and manufacturers continues.
If you have concerns about vaccines, your doctor can help you evaluate potential benefits and risks for your individual health.
