So far, the COVID-19 vaccines have only been fully tested on adults. Children’s immune systems are different from adults and their immune systems can even vary at different ages.
This fall, the Pfizer COVID-19 vaccine trials started to include children as young as 12, but the results aren’t available yet. We anticipate more and more clinical trials to begin expanding recruitment to other age groups. The bottom line is that more research is needed to ensure the vaccine will be safe and effective for infants, kids and teens younger than 16.
