Schools in the United States should continue to use masks for the 2020–21 academic year as not all students will be fully vaccinated, the U.S. Centers for Disease Control and Prevention (CDC) said on May 15.
In its latest guidance, the CDC said all K–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 said fully vaccinated people do not need to wear masks outdoors and can avoid wearing them indoors in most places in a May 13 statement.
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.
In early May, U.S. regulators authorized Pfizer and BioNTech's COVID-19 vaccine for use in children as young as 12 years old.
