Schools in the U.S. should continue to use masks, C.D.C. advises.

The Centers for Disease Control and Prevention on Saturday clarified coronavirus advice for U.S. schools, recommending the continued, universal use of masks and physical distancing, after the agency’s sudden announcement that vaccinated Americans could forego masks indoors.

All schools teaching students from kindergarten through grade 12 should continue to implement proper mask-wearing through the end of the 2020-2021 school year, the C.D.C. said. The agency also kept in place its suggestions to observe physical distancing and to test for coronavirus infections.

The couple in the website videos could be hawking any number of products.

“You’re going to love owning the platinum package,” Charlene Bollinger tells viewers, as a picture of a DVD set, booklets and other products flashes on screen. Her husband, Ty, promises a “director’s cut edition,” and over 100 hours of additional footage.

Click the orange button, his wife says, “to join in the fight for health freedom” — or more specifically, to pay $199 to $499 for the Bollingers’ video series, “The Truth About Vaccines 2020.”

The Bollingers are part of an ecosystem of for-profit companies, nonprofit groups, YouTube channels and other social media accounts that stoke fear and distrust of COVID-19 vaccines, resorting to what medical experts say is often misleading and false information.

An investigation by The Associated Press has found that the couple work closely with others prominent in the anti-vaccine movement — including Robert F. Kennedy Jr. and his Children’s Health Defense — to drive sales through affiliate marketing relationships.
