There's a lot of misinformation about vaccines online, and sometimes well-meaning parents fall into rabbit holes of conspiracy theories and made-up "facts." While they often intend to protect their children,[1] not vaccinating has the opposite effect,[2] [3] [4] [5] and leaves kids more vulnerable to dangerous and even deadly diseases.

Please keep in mind that while experts agree that vaccines are safer than the diseases they prevent[6] and that serious side effects are extremely rare,[7] [8] [9] it's usually good for a trustworthy adult to supervise you during and after the event. Try to tell your parents or guardians so they can help you in the unlikely event of a problem.
