COVID-19 vaccines are being rolled out to adults who are most at risk from the coronavirus, but ending the pandemic will require vaccinating children too. Researchers are beginning to test younger and younger kids to make sure the shots are safe and work for each age. Pfizer and Moderna expect to release results soon showing how their two-dose vaccines performed in people ages 12 and older. The companies recently launched studies involving younger ages. In Britain, AstraZeneca began a study among 6- to 17-year-olds. And Sinovac recently announced it has submitted preliminary data to Chinese regulators showing its vaccine is safe in children as young as 3.
