>> booster shots for people with weakened immune systems are getting the green light now from the fda will get either pfizer or moderna the mrna ys. it's unclear when those shots will start to actually be administered. but it's expected to be quite soon. our had that fred, the doctor peter chin hong from ucsf. he joins us now to talk about the booster, the recent vaccine requirements. >> an ounce for san francisco in a whole lot more. let's with squid and kick it off here with the booster is it just for immunocompromised people are 65 plus or do you decide who gets a

>> well, vicki, the lowest hanging fruit is definitely the email compromise patient population and even within that group, there are those who i even more immunocompromised and others. so i think what you'll get from the cdc in the next few days is clarity on who a month stay in compromise going to be included. definitely solid transplant. definitely people stem cell born march on spots of people may hear some kinds of chemotherapy. we're waiting to hear the rest in terms of people over 65 even though approved in some other we're still waiting on that guidance. we haven't seen a lot of breakthrough hospitalizations with people who are just over 65 without being immunocompromised. we have seen hospitalizations in those who vaccinated, who are immunocompromised coming in just last week i was taking care of some of these patients talking a lot about needing to

prove you're vaccinated soon in san francisco to enter indoor. >> areas. what about outside? we have these concerts that are outside. >> yeah. the giants and a's games. the forty-niners soon. people packed together not needing to wear masks. technically, how safe is it to be outside now with delta. >> that's a great question. we do know that in the pre delta days being outside was 20 times, less risky than being inside. so if you take a vaccinated person, our doors, even the fee, some delta. and you know, that else's twice as likely as infectious as the previous variance. then you know, is still talking by a very, very little wrist. you take an unvaccinated door is with a risky spent on bunch of people crowded closely together. you can see how that might be risky. so it's you know, the behaviors ride them being indoors you can be the

only person in a trader and that will be relatively wrist free. this is being, you know, being very intimate with somebody outdoors who is we don't know the side of 7 that could be risky as well. it sounds like a a numbers >> back to the vaccines were she also hearing them the moderna it tends to be a little bit more effective against the. >> the delta variant. why is that? why i mean, pfizer's similar. type of vaccine. so. how do you explain it. >> i think the study findings were frankly baffling to many people, including myself. i think what is consistent amount of what study look at is that both vaccines pfizer moderna and j j to some keeping people away from the hospital. if you think about the outcome we care most about is making someone super sick enough to go to the hospital.

and in that all vaccines in operation warp speed and doing a fine job. so i got pfizer. i'm not rushing out to go and get moderna now, example. >> so many of us have spent so much time over the past year and a half doing everything we can to avoid the virus. but delta has kind of changed the game. it seems do we as a society need to kind of mentally emotionally get comfortable with the fact that we're probably at one point going to inhale the virus that sars covid too. but if you're vaccinated, then it might not turn into covid the disease and you'll be fine. but will all sort of inhale. the virus. >> you're right. grand. i think at the end of the day. >> some, you know, at some point all of us will probably be exposed sars covid 2 that causes covid. but we just want to make sure you know, people vaccinated that they don't end up in the hospital. we have to be able to learn to live with this. as you said, we can't

shut down businesses every time there is infection as long as the hospitalizations, a stable right now we're in this really bad limbo because we have infection risk. but we also have high hospitalization rates because of the wide swath of people who i not vaccinated and you can see that in the states where there is very low vaccination rate. they're really missing the scenes of the hospital is kind of like 2020 all over again. >> oh, boy, that's a nightmare i'm ok, gentlemen, you were talking about inhaling the virus. let's talk about schools air filtration systems is that something that? school should be installing. and is it effective. >> yes. so they are portable half of areas could be another layer of protection. but it's not a mandatory thing. the way i think about enhancing safety in schools. the most important thing parents can think about

is vaccinating all the adults in the kids like that. a good ineligible vaccinations under 12. that is teachers staff grandparents parents cousins, brothers sisters. what older the next set of things are just sort of like icing on the cake. there are. many of the things that schools use and the cdc is deliberately written their guidance and that way. so there's masking, which i think is the relatively straightforward relatively easy to implement cheap. there is ventilation. you open the window. we live in california. it's hopefully i will be relatively easy to do. 3 feet apart, not a game changer for schools that can do it, but you know, half of filtration might be one thing that some rooms mike invest in. so. they are bunch of different things that people can do testing, of course, is another strategy like what stanford started announced

going to start to do once weekly. so you have a bunch of different things. but vaccination is the most important thing second wasn't one thing. and there was one thing mice by before and then you can choose from the press. we're going to be ok. we're definitely going to be ok, i'm going each other person i promise. and you know, we'll you know, we'll have chairs or saludo. what have you. >> all right. peter chin, hong, i always a pleasure to watch. have you on the program. you're so informative and thank you for leaving us with that positive definitely thanks. grant. vicki that. thanks. thank you. and by the way, you can stay with kron 4 always for continuing covid coverage. >> just scan the qr code with your phone. you'll be directed to our web page dedicated to covid. it's all on kron. 4 dot com. plans to repopulate areas evacuated due to the dixie fire have been canceled cal fire had originally planned to
