Students and teachers vaccinated against Covid-19 will not need to wear masks in US classrooms when school resumes in the fall, health authorities said Friday. The new guidance follows the recent federal approval of the Pfizer-BioNTech Covid-19 shot for Americans aged 12 to 15, with hospitalizations and deaths down sharply since January — but cases beginning an upward trajectory due to the surging Delta variant of the coronavirus. The Centers for Disease Control and Prevention (CDC) had announced in May that vaccinated Americans could drop masks, but the health advice for schools was not immediately changed accordingly. “Indoors: Mask use is recommended for people who are not fully vaccinated, including students, teachers, and staff,” the nation’s lead federal public health agency announced in its updated guidance.
