CDC says schools should still universally require masks and physical distancing

The Centers for Disease Control and Prevention updated its guidance for K-12 schools Saturday, noting that reopened schools should "require universal and correct use of masks and physical distancing."

Why it matters: The clarification comes after the CDC's announcement Thursday that fully vaccinated people no longer need to wear masks or physically distance indoors or outdoors.

Of note: On Friday, NIAID director Anthony Fauci said that children younger than 12 probably won't be vaccinated until the end of 2021, and will need to wear masks at school this fall.
