ryaner. this delta variant is twice as infectious as small box and in a way, i know it's not technically correct but for all intensive purposes and practical purposes, we should be treating it as a different disease. the way in which it super infects people who have had the disease before or who have been vaccinated and makes it possible for you to then spread the disease is quite different. we have to remember there is three parts to what the vaccine does. stopping you from getting it, stopping you from getting sick, getting hospitalized or getting dead and stopping you from spreading it. does a great job in the middle, not as great as we'd hoped in the two ends and for that, we're going to look for masks. so we're going to go back, i think, a little bit to vaccination for you, for me, and masks for our friends, our children and our neighbors. >> so dr. ryaner, to this point it interesting dr. birilliant yu frame it as a different disease. dr. ryaner, the biden administration said breakthrou

. >> first of all you had carl ryaner. >> carl ryaner got his start on show of shows with sid cesar which not a sitcom, it was a variety show. >> it's supposed to be tent. >> the writer's room, the talent just had carl with that's a place, that's a gold mine. a writer's room is a gold mine and i remember talking to myself on the way home and said what piece of ground do i stand on that nobody else stands on? so i'll write about the life. i'll write. >> writers are lazy. people write what they know. >> we got a sketch. >> there is nothing to worry about, kids. i have got an idea. he will play the part of a talking bully pin. >> i thought it was the greatest idea because in most sitcoms, you don't know what the husband did for a living. >> the second number should come before the big sketch. >> gee, i don't know. >> i like it. >> now i like it. >> yeah, me, too. >> i like it, too. what do you know? look at the tie you're wearing. >> i love the fact it was a glimpse into the writer's room. seeing how shows worked -- pastfascinating to me. >> this dress is years old. >> it still works. if i'v

ryaner, thank you very much.r time as i always do. >> my pleasure. >> i want to bring in the democratic mayor of st. louis. she instituted a mask mandate amid a surge of cases there. mayor jones, appreciate your time there. i know the mask mandate you put into place went into effect yesterday. do you feel like the new guidance from the cdc validates your decision? >> absolutely. the biggest push back i was getting from regular citizens was, you know, why aren't you following the cdc guidelines so today's decision by the cdc for those who are vaccinated and unvaccinated to wear masks especially in areas where there is high transmission definitely validates the decision dr. paige and i made. >> i know obviously you're seeing incredibly high transmission and you seem to reference there you're facing a backlash over the mask mandate. the attorney general states suing you. other small business owners and some of your constituents have been pushing back on the decision. here is a bit of what they've been saying. >> i d

ryaner, the pfizer ceo says a third booster shot increased antibodies five fold in younger people and tenfold in older. the biden administration is telling vaccinated people don't get a booster shot but you do needs to wear a mask. it does really seem done -- confus confusing. >> it does and we need a central clearing house for this kind of data to the american public. i don't want to hear this on an earnings call from pfizer. look, there are two pieces of information. the announcement that a third shot increases antibody levels, that's just biology. that's what vaccines do. that's what they should be expected to do. good. you get higher antibody levels with a third shot. i expect that. the other piece of data is do we need it. pfizer released a preprint of the six-month data that shows a relatively modest decrease in efficacy in six months. the efficacy for vaccine of preventing simatic infection drops from 96% to 83% or so out at six months but importantly, prevention of severe disease which is really what this whole ball game is about does not change a bit. it remains 97% out. we c

. >> in terms of that trust and that confidence, i want to bring in our medical analyst, jonathan ryaner, a professor of medicine and surgery. in terms of trust and kr confidence, we know the white house has been really talking about how much damage, misinformation has done in this push to get more people vaccinated. but there was a moment at cnn's town hall that i think gave a lot of people pause. take a listen. >> one last thing that's really important is we're not in a position where we think that any virus including the delta various which is much more transmisable, and more deadly in terms of nonvaccinated people, the various shots that people are getting now cover that. you're okay. you're not going to -- you're not going to get covid if you have these vaccinations. >> so part of that, yes, we know that these vaccines from what we know so far from the studies and the data we have so far, they do protect you against the delta variant, but they don't, none of the vaccines, mean that you will never get the virus. how do you think -- how damaging is that statement? >> right. well, i do
