CDC change on masks brings U.S. back in line with WHO and foreign governments

The use of masks to control the spread of the coronavirus has been divided geographically all along - with many Western countries late to recommend the use of face coverings already in wide use in East Asia.
But when the U.S. Centers for Disease Control and Prevention announced new guidance in May suggesting that vaccinated people no longer needed to wear masks, indoors or out, the United States joined a far smaller list of Western countries to move away from mask usage before the end of the pandemic, in the face of well-evidenced efficacy.
