The largest nurses union in the U.S. called on the CDC Saturday to reverse guidance issued this week that allows for people fully vaccinated against COVID-19 to go maskless while participating in indoor and outdoor activities.

Details: National Nurses United executive director Bonnie Castillo said in a statement the new guidance is "not based on science, does not protect public health, and threatens the lives of patients, nurses, and other frontline workers across the country."

"Now is not the time to relax protective measures, and we are outraged that the CDC has done just that while we are still in the midst of the deadliest pandemic in a century."
— Castillo

The other side: CDC director Rochelle Walensky noted when the guidelines were issued Thursday that few people vaccinated against the coronavirus had become infected with it, that "transmission seems rarer still" and the vaccines seem to protect against known variants in the U.S., per the New York Times.

  • The CDC did not immediately respond to Axios' request for comment.

How retailers are responding to the latest CDC guidance

Some retailers across the U.S. will continue requiring masks in stores, despite new coronavirus guidelines from the Centers for Disease Control and Prevention relaxing mask mandates for fully vaccinated people.

The latest: Starbucks announced that masks will be "optional" for fully vaccinated customers starting May 17 "unless local regulations require them by law." Employees will still be required to wear face coverings and restrooms will remain closed to the public in stores where indoor seating is not available.

NIAID director Anthony Fauci said Friday that children who have not been vaccinated for the coronavirus will need to wear masks in schools this fall, CNN reports.

What they're saying: Fauci said that children in schools need to wear masks "when they're out there playing with their friends and, you know, particularly in an indoor situation."
