Pfizer announced on Wednesday that its Covid-19 vaccine is safe and strongly protective in children as young as 12 years old.
This was seen as a step toward possibly beginning shots in the age group before they head back to school in the fall. Pfizer’s vaccine is authorised for ages 16 and older.
In a study of 2,260 US volunteers ages 12 to 15, preliminary data showed there were no cases of Covid-19 among fully vaccinated adolescents compared to 18 among those given dummy shots, Pfizer reported.
The study will continue to track participants for two years for more information about long-term protection and safety.
