The mask guidance announced by the CDC on Tuesday provoked frustration among fully vaccinated Americans. But not directed at the agency. Many fully vaccinated people told USA TODAY they’re relieved the CDC is recommending they wear masks in indoor settings again where COVID-19 transmission is high. They’re more frustrated the mask guidance was lifted two months ago, which may have contributed to high transmission rates among the unvaccinated. In a briefing Tuesday, CDC Director Rochelle Walensky said the agency’s guidance was triggered by science that showed some people infected with the delta variant after vaccination can spread the virus to others. According to the science, she said, fully vaccinated people with breakthrough infections from the delta variant have a similar viral load to infections in unvaccinated people, which means fully vaccinated Americans can spread the virus more easily than previously thought. Health experts said there's hardly any transmission among fully vaccinated people, so they doubt the CDC guidance will affect community spread. #covid #covid19 #coronavirus
