COVID-19 vaccines for kids: What you need to know

Is there any research on the long-term effects of the Pfizer-BioNTech COVID-19 vaccine?

Because COVID-19 vaccine clinical trials only started in the summer of 2020, it's not yet clear if the vaccines will have long-term effects. However, vaccines rarely cause long-term effects.

A portion of the children ages 12 through 15 enrolled in the ongoing Pfizer-BioNTech COVID-19 vaccine study were monitored for safety for at least two months after being given the second dose of the COVID-19 vaccine.

As part of its first request for emergency use authorization of its COVID-19 vaccine in 2020, Pfizer Inc. created a safety monitoring plan. The plan now includes the monitoring of adolescents given the COVID-19 vaccine.

In addition, in the U.S. all vaccination providers are required to report serious adverse events, such as allergic reactions, to a national program called the Vaccine Adverse Event Reporting System.
