Data from other countries but there were three separate data sets they showed showing that the effectiveness against infections from coronavirus was going down, all infections. whether it was asymptomatic, meaning people didnt have any symptoms at all or people getting sick. they aggregated all of that data. they were looking at health care providers and frontline workers. heres what happened when you predelta and then delta the majority. and the bar graph on the right is nursing homes specifica...

That while protection against infection may decrease overtime, protection against hospitalization is currently holding up pretty well. as we make decisions about boosters we have to look at effectiveness in the specific context of the delta variant. preliminary data from august 6th from two of our cohort studies that include more than 4,000 health care personnel, first responders, and other front line workers show waning effectiveness in the context of the delta variant. from 92% prior to delta,...

Were talking about last week, and i talked to some of these officials myself last week, the data here in the united states looked good in the sense that the vaccines were working well and there wasnt discussion or a plan for boosters. just last week out of the cdc. what they say tomorrow, this announcement, anderson, is that there will be more data presented, some of it u.s.-based data. not just data from either israel or the uk. and they say its going to make the case that there is evidence of ...

Driving this change? >> i think this is a really important point, kate. i dont think youre going to sedate that that has shown a decrease in effectiveness or a significant decrease in effectiveness against hospitalization and death. youre quite right. i think for a long time the message coming out was, until we hit certain criteria, triggers an evidence of that decrease in effectiveness against hospitalization and death, we probably wont be doing boosters. now what theyre saying is this is a lit...

But i label that as the base reason for what weve seen happen. >> youve been trying to answer the question, how did we lose this war? you said corruption was part of the problem. as is well known, the effectiveness of soldiers and police suffered because government officials or military commanders pocketed their pay, hoarded their ammunition, and diluted rosters with ghost soldiers. a stronger explanation was that the police and soldiers did not want to put their lives on the line for a governme...

Afterwards. so all of this was sort of predicted and predictable and based on the urgency at the time. a lot of us were expecting a booster. when you look at the data and coming out of israel and mayo clinic study, there is a sharp decline in effectiveness against infection going from over 90% to 40% to 50%. the unknown that i havent seen a lot of data in is the hospitalizations. so we know were seeing breakthrough cases. but whether were seeing breakthrough hospitalizations, theres a little bit...

They are also bolstering data from israel. basically, this is sort of whats happened over time. you look at moderna, you look at pfizer, january compared to july. and you do see some waning effectiveness against the infection. now, let me just, let me just give you a little bit of context here when you look at data like that. theyre basically looking at anyone who got tested, right, and people that came back positive. so this kocould be people who we not tested, surveillance for traveling, could...

Forces here. having said that, you know, the united states has hasnt released a lot of data on what is happening with the vaccinated population overall. were looking at data from israel, data from the u.k. and there is some indication, if you look at that data, that the vaccines effectiveness may start to wear down and people may start to become more likely to get symptoms, bad colds anz things like that. not bad enough to land them in the hospital, but bad colds. so putting it altogether for me...

Your vaccine wanes in efficacy over time or the delta covid surge has people thinking get more protection. a little bit of both? >> its really a little bit of both. john, let me be clear the data that biden administration is making these recommendations off of is still very preliminary and these booster shots have not yet received fda approval for anyone except for the immuno suppressed, the folks we heard about the news last week. people on chemo or high dose steroids or immuno suppressive diso...

Are being recommended. it sounds like its happening, the shots will be available. we checked into supply. the shots, the number of shots will be available. but in terms of the actual science, im sort of laying it out for you there. >> so that was the science. i guess the administration, the reporting is lalso looking at results in israel that looked at more people, has tracked them more. there is some fear that its not just a decrease and effectiveness against infection, but also potentially ser...
