breaking headline we learned just before we came on the air tonight. The fda has just authorized the pfizer vaccine for children 12 to 15 years old. This means millions of young people will be vaccinated and the hope, of course, that both shots will happen well before the next school year.

Dr. Anthony Fauci saying as cases come down in the U.S., the CDC will likely look at loosening guy dance for masks indoors. Also suggesting the possibility of seasonal masks depending on what we see with the virus as we move forward. But first tonight, news on that emergency use authorization for pfizer and adolescents and ABC's Victor Oquendo leading us off tonight from Miami. Reporter: Tonight, a major step toward the vaccination of millions of American children. Doesn't hurt at all. Reporter: The fda authorizing the pfizer vaccine for 12 do 15 year Olds after the company reported it was 100% effective in adolescents, with no safety concerns.
