The Centers for Disease Control and Prevention updated their public health guidelines for schools on Friday, saying that fully vaccinated teachers and students are not required to wear masks in school buildings.

The CDC’s new guidance comes about two months after federal health officials approved the use of the Pfizer BioNTech Covid vaccine for children ages 12-15, so middle and high school students could get the syringes before the fall semester can.

Teachers and students who are not vaccinated should continue to wear masks indoors, the agency said. Practice is especially important when it cannot be followed indoors and in crowded environments.
