How do we know COVID-19 vaccines are safe for kids?

Tens of thousands of volunteers were involved in clinical trials for the vaccines. The clinical trials showed that the COVID-19 vaccines are remarkably safe and effective before they got FDA emergency use authorization. Clinical trials are now underway to study whether children as young as six months old could receive COVID-19 mRNA vaccines.

Nearly half of all kids 12- to 17 years old in the U.S. have been fully vaccinated! That's more than 11 million kids who have had both of their doses of COVID-19 vaccine. The vaccines continue to be monitored very closely. In fact, the Centers for Disease Control and Prevention (CDC) say that COVID-19 vaccines will have "the most intensive safety monitoring in U.S. history."

Is there any research showing long-term effects?

Your child may experience some mild or moderate short-term side effects (similar to adults), but there has been no indication that there are any long-term effects from the COVID-19 vaccine, including impacts on fertility. 

Vaccine monitoring has historically shown that side effects generally happen within six weeks of receiving a vaccine dose. For this reason, the FDA required each of the authorized COVID-19 vaccines to be studied for at least two months (eight weeks) after the final dose. Millions of people have received COVID-19 vaccines, and no long-term side effects have been detected.

If you have questions specific to your child, reach out to your medical provider.
