Update 3:29 p.m. ET : At a press group discussion held Tuesday afternoon , CDC Director Rochelle Walensky laid out the changed guidelines . The CDC will now recommend that full vaccinated people hold out mask in public indoor options in areas with “ material and high ” transmission . to boot , the CDC will recommend that children , staff , and visitors continue to wear masks in public K-12 schools , regardless of inoculation condition . The CDC ’s county - level map of transmission risk can be seenhere .
In announcing this decisiveness , Walensky cited new data suggest that immunised people infected with Delta may be more likely to transmit their infection to others compare with old strains of the virus ; prior data point hadsuggestedthat , in grammatical case where a immunized person view the computer virus , they exuviate very little of it and were therefore less likely to broadcast it . The Delta strain , it seems , is simply more transmissible than others .
Walensky underscore , however , that breakthrough infections remain rare and that unvaccinated people remain the highest at risk for sickness and destruction from the coronavirus and that they should get immunize as shortly as potential . “ The Brobdingnagian absolute majority of transmission , hard disease , hospitalization , and demise is almost entirely happening among unvaccinated people , ” she said .

The CDC is set up to recommend mask - wearing for people vaccinated against covid-19 , at least some of the prison term , according to reports from the New York Times and CNN . The alteration in guidance , which will reportedly materialise today , is due to grow concern over the more communicable Delta variant of the coronavirus . At this time , however , detail are scant on the literal changes that the CDC will recommend to the public .
Inmid - May , the CDC surprise many hoi polloi , including public health experts , by unloose new , much - relaxed rule of thumb for in full vaccinated people ( fully immunized being defined as two workweek after your last scheduled dose ) . immunized people would no longer need to wear masks in most indoor situations , except when on public transmit or in certain high - risk environments , like in medical facilities . And they could safely interact with chemical group of immunised or even unvaccinated people from a single household , the CDC advise . immunized masses were also told that weary masquerade out of doors was unnecessary , even in large crowds , while unvaccinated people could take off their masque while practise .
The guideline werequickly criticizedby many public health expert . Some argued that the steering would promote unvaccinated people to stop over wear out masque themselves , in absence of a clear way to distinguish inoculation status , and conduct to spike in new cases . Other expert , while generally supportive of the policy , argued that it was announced with no advance card and lilliputian forethought for how local politics and businesses would have to sail and put through change play about by it .
The unmasking policy did n’t seem to lead to solid jumps in new example , and , until of late , cases had continued to decline substantially from the largest peak earlier this year . But in late week , the emergence of the Delta variance ( first find in India ) seems to have change the berth . More than 80 % of raw case arenow thoughtto be make by Delta , and , much like other countries where Delta has become dominant , like the UK , daily caseshave once again begun climb back up in the U.S. Hospitalizations and deaths have slightly rear as well , though are still far below their pinnacle .
There ’s also some data from Israel suggesting that while the mRNA vaccines stay highly efficient at preventing serious illness from Delta , they might be substantially less efficient at preventing any illness at all , which would be a sharp departure from their carrying into action against past melodic line . This data , it should benoted , does possibly conflict with data from other countries like the UK and Canada , which hassuggestedthat the vaccines remain about as efficient as against other strains . And unvaccinated people rest at much higher danger from Delta than those fully immunised . But some scientists havewonderedwhether vaccine - provided immunity may be wane in the earliest group of people who received the shooter late last year .
These new developments seem to have shape the await alteration in guidelines . Anthony Fauci , theater director of the U.S. National Institute of Allergy and Infectious Diseases and the master aesculapian advisor to the president , stated over theweekendthat changes were being actively considered due to the rise in case . On Sunday , concord to CNN , Union officialsmetto talk over possible changes . And New York TimesreportedTuesday morning that these changes will be announced later today .
At this point , though , all that ’s known is that the CDC will reportedly call for vaccinated hoi polloi to wear masks indoors under “ certain luck , ” according to the NYT . As this story is developing , we ’ll bring you updates as they get .
