How do the COVID vaccine trials for children work?

Health care workers answer questions about the COVID-19 vaccines.

Yvonne Maldonado, MD explains the process for making the COVID vaccines available for kids.

All of the trials actually started with adults and that is normal. For most vaccines, the earliest trials are done in adults. And then trials are moved into younger and younger ages depending on the product and the need for a vaccine. So the Pfizer vaccine trial started in adults and then moved to 16 year olds and then moved to 12 year olds.

There are a number of trials going on now for children under 12, primarily Pfizer and Moderna, and I think Johnson and Johnson is starting as well. Those trials are underway now and it is anticipated that there might be data in the early fall to submit to the FDA for consideration.
