The agency now recommends that vaccinated people be tested for the virus after contact with a person infected with the new crown, even if they do not have any symptoms.
Previously, the health agency said that after a fully vaccinated person comes into contact with an infected person, if they have no symptoms, they do not need to be tested.
"Our updated guidelines recommend that people who are vaccinated should be tested whether they are symptomatic or not." CDC Director Valensky told the New York Times, "The testing methods are extensive."
CDC Director Valensky said that the change in this guideline is due to new data showing that people who have been vaccinated may still carry a large amount of the virus and spread it to other people after being infected with the delta variant virus.
The agency also recommends that vaccinators who are in close contact with unvaccinated people, regardless of the transmission rate in the local community, should consider wearing masks in public indoor spaces.
These unvaccinated people include children under 12 years of age.
Unlike previous attitudes, the agency also recommends that everyone in school wear masks.
