In delivering vaccines, pharmaceutical companies aided by monumental government investments have given humanity a miraculous shot at liberation from the worst pandemic in a century.
But wealthy countries have captured an overwhelming share of the benefit. Only 0.3 percent of the vaccine doses administered globally have been given in the 29 poorest countries, home to about 9 percent of the world’s population.
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.
New mask guidance for vaccinated individuals does not grant permission for widespread removal of masks, Centers of Disease Control and Prevention Director Dr. Rochelle Walensky said on ABC's "This Week" on Sunday.
