More than 3 million teens between the ages of 12 and 17 years old have gotten at least one COVID-19 shot, as of Monday, according to the Centers for Disease Control and Prevention. The public health agency does not break out more specific age categories on its COVID Data Tracker page; however, it says that about 157 million people over the age of 12 have received one dose of a vaccine, and about 154 million of those shots went to people who are at least 18 years old. Federal regulators last week authorized the BioNTech SE and Pfizer Inc. two-dose, mRNA vaccine for use in teens between the ages of 12 and 15 years old, making it the first vaccine available in the U.S. to this group of younger teens. (The shot had previously been authorized for anyone who was at least 16 years old.)
