1. There are trials underway in adolescents

We are perhaps three months away from vaccinating people under 16 years old.

The first two vaccines to receive emergency use authorization in the United States for adults are now in clinical trials for young people, with initial results expected by summer. Pfizer and BioNTech have completed enrollment of more than 2200 volunteers ages 12 to 15, and Moderna is wrapping up recruitment of a planned 3000 volunteers with the same minimum age. Both vaccines are based on messenger RNA coding for the coronavirus spike protein, which prompts production of protective antibodies. Another three vaccines, which use a harmless virus to deliver a gene for the same protein, are also taking steps toward pediatric authorization. On 12 February, AstraZeneca and the University of Oxford announced they would begin to test their vaccine in 300 U.K. children ages 6 to 17. Johnson & Johnson, whose adult vaccine will be considered by U.S. regulators this week, says it's moving toward testing in young people, and Sinovac Biotech is testing its product on children in China ages 3 to 17.
