In late july and another study looking at nursing homes saw a drop from 75% effectiveness in march to 53% in august. "outfront" with me now is the cdc director dr. rachial walensky. we heard from administration multiple times including as recent as last week the thirty shot is not needed because the vaccine protects against severe disease. why are boosters needed if it does protect against severe disease? >> were monitoring this data in realtime in cohorts across the country and what were findin...

Network, randomized clinical trial thats the gold standard randomized clinical trial found n-95s produced no significant difference in the transmission of influenza, not that different from covid. no significant difference the truth is there really havent been very many studies on the effectiveness of masks, real randomized control trials on the effectiveness of masks there has been occasional data and thats what the cdc relies on. but many say of those studies that have been done, that masks re...

Now. you have been independent voice when it comes to covid. i open up anything i just said to your disagreement or correction. i also want to ask you this moving forward. you have done a lot of research on therapeutics on the effectiveness of early intervention in treating covid. why are you alone? why is that information so hard to find? , thank you for having me this evening. i actually agree with essentially everything that you said in your five points. i am not alone that i have two interne...

Talking about the issue yesterday and the fact that theyve been preparing on the supply side of things for months now, and thats despite the fact that public health officials have said the vaccine is effective against the delta variant and other mutations but clearly the white house and the covid-19 team has had contingency plans in place. what we are expecting today is some sort of justification for why an eight-month time line for getting a booster shot after that second dose. we know theres b...

Workers to get vaccinated if the nursing homes get federal dollars. all of this is part of continued efforts by the biden administration to increase shots in arms. lets bring back cnn white house correspondent kaitlan collins as well as our chief medical correspondent dr. sanjay gupta. and, sanjay, we were talking about this yesterday. the world health organization says that evidence is lacking as of now that booster shots are needed for fully vaccinated people. so, why is the biden administrati...

>> tell helps a lot on those. this as hospitals all over the country are running out of room to treat patients. lets go to our chief medical correspondent dr. sanjay gupta. i know you spoke with a senior federal health official about whats to come. what did you learn? >> what i learned is that for the first time were going to see some data from the united states thats going to make the case that the vaccines do tend to have a little bit of waning effectiveness against mild or moderate disease, n...

Saying were seeing some evidence that overall the protection is going down over time, but its pretty clear that delta has accelerated the level of protection going down. i want to point out, its been a little confusing because people heard even just yesterday that booster shots were not necessarily being recommended. they heard that from the cdc. today obviously a very different tune. at the same time, theyre saying, hey, boosters are probably going to be necessity because we think this is going...

>> this demonstrates that vaccine effectiveness declined from 75% in march to 53% in august 1, 2021. this represents a substantial decline in the vaccines effectiveness. >> sandra: does that mean i was told that the pfizer vaccine is 95% efficacy rate. right now its only 55%? is that what i take away from that? >> it is. over a period of time. as time goes on. 6 to 9 months, the protection against getting the infection goes down. it was 95% within the first couple of months. it drops. number, tw...

Are the same as those that issues this significant recommendation. it is as soon as september 20th. there has been data to show the effectiveness of the vaccines and were talking in this case about pfizer and moderna waiving over time. the incidents, the production against mild to moderate disease is really beginning to wane among those older populations. what is so significant is that those elderly populations, they would have been the very first to receive those doses when they began really go...

What they seem to be saying, and its an interesting sort of discussion here, theyre saying were trying to get ahead of this. because were seeing evidence -- this is u.s. data from nursing homes, hospital systems, large number of people in the general population, theyre saying since were seeing this decreased effectiveness against mild or moderate disease, were worried that will start to lead to decreased effectiveness against hospitalizations and death. havent seen that yet, but thats a concern....
