The World Health Organization has urged governments not to lift pandemic restrictions too quickly – including saying everyone, even the vaccinated, should continue to wear masks given that the COVID-19 delta variant spreads more easily and no vaccine is 100 percent effective.
In the U.S., the Centers for Disease Control and Prevention maintains it still is safe for the fully vaccinated to go mask-free. But there’s no way to know if maskless people really are vaccinated and local governments can set tighter guidelines.
This week, with the delta variant spreading locally, health officials in Los Angeles County said they still recommend masks indoors in public places for everyone.
If that’s confusing, consider that the more the virus is spreading in a particular area, the more risk even the vaccinated have of getting a mild or asymptomatic infection they could spread to someone not protected – such as children too young to qualify for the shots.
