The CDC in its latest guidance said all kindergarten through grade 12 schools “should implement and layer prevention strategies and should prioritize universal and correct use of masks and physical distancing.”
The recommendation comes after the agency on Thursday said fully vaccinated people do not need to wear masks outdoors and can avoid wearing them indoors in most places.
The CDC said masks should be worn at all times by all people in school facilities and buses, while maintaining a six foot distance between teachers and students. Earlier this month U.S. regulators authorized
and BioNTech’s COVID-19 vaccine for use in children as young as 12 years old.
