- Pfizer is expanding its massive coronavirus vaccine clinical trial, opening the study to include children as young as 12.
- The company is poised to become the first major drugmaker to start testing a COVID-19 shot in kids in a large-scale study.
- The New York pharma giant said it got permission to boost the study’s overall size to as many as 48,400 volunteers.
- Pfizer broadened the study last month to include 16- and 17-year-olds as well as people with HIV, hepatitis B, or hepatitis C.
- While early clinical results were promising, it remains to be seen if Pfizer’s vaccine — or any other experimental shot — can prevent COVID-19.
- Pfizer CEO Albert Bourla has said he expects data from this study before the end of October.
