Sources say the COVID-19 vaccine from Moderna is only recommended for adults 18 and over and Pfizer 16 and older. Looking forward, by 2021 spring, children who are 12 years old and older will possibly be allowed to be vaccinated. They also said that this might not be the same for younger ones. Around three thousand children aged 12-17 are currently enrolled in the Moderna COVID-19 testing program. According to Dr. Kawsar Talaat, the lead investigator of the Johns Hopkins adult phase 3 research site for Pfizer, Pfizer has only completed the first doses for two thousand children aged 12-15.
