Pfizer was already testing its vaccine in kids aged 12 to 15. Moderna has been testing its vaccine in those aged 12 to 17. And this month both companies began trials in children aged six months to 11 years. Johnson & Johnson recently described plans to test its vaccine in young children and adolescents, too.
