yeah, go, i'll just, there are london a spring in doctor dennis nash. she's a distinguished professor, happened to me. ology at the 15 of us in new york, he joins a spy skype. money, thanks for joining the program. what do you make of my crimes comments? all countries making a very premature, rushed back to full normality. i agree with, with mike ryan w h o, i do think there are some situations in different places around the world that are opening up prematurely. the really important thing is to ensure that prior to opening up their high enough levels of vaccine coverage so that you can protect as many of the most vulnerable people in a given society as possible. and that, in my view, makes it really important to say we can, you can tie, opening up to achieving certain levels of vaccine coverage and do it in a phased way or incremental way. so for example, when 40 percent of coverage is achieved with the vaccine workplaces can reopen with certain restrictions. and when 60 percent coverage is achieved, there can be fewer workplace restrictions, or maybe

so now joined via skype by dennis nash. she's distinguished professor of epidemiology at the city university of new york and graduate school of public health. so if you could just describe for us, if you can, because i suppose dater and evidence is still being clarified on this. how effective are you is while pfizer all astrazeneca randy and almost done or any the vaccines out there against the the dells her strain of the corona virus. yeah, i mean, obviously we're still learning a lot about how long the fax scenes will remain effective. because the panoramic has really only been around for a year and a half. and so we're learning as we go to be sure it's important to be thinking about the need for boosters and also routinely booking for the extent to which the vaccines may result in breakthrough infections. importantly, with severe disease, time will tell, but of course we need to be thinking about and planning about it because it may become important. but i do agree that it's not the time to be prioritizing a 3rd dose and

when will we be able to return to normal doctor dennis nash as a professor of epidemiology at the city university of new york. he says the u. k. should vaccinate at least 70 percent of its population before lifting restrictions . well, last i looked, i think the u. k is gotten to about 50 percent coverage with and thinking about fully covered with 2 doses of vaccine or one dose of, of a single those back seen. i think that clearly we're seeing a search in cases in the u. k. and that suggest to me it's not enough. and while we haven't yet seen surges and death rates there, we're beginning to see increases in the death rates while they're still very low. they've probably increased 2 or 3 fold over the last few weeks. and to me that's something to watch. and i know they've said a deadline of july 19th to to fully reopen a lot can happen in 2 weeks. a lot of people could be vaccinated between now and then i would really like to see rather than set an arbitrary date. you know, forrest johnson to say, if we can achieve, say 70 percent coverage between now and then. then we can begin to think

dennis nash, thank you very much indeed for talking to somebody there. thanks for having me. what news are from london, phil ahead? wildfire was in the arctic, siberia se welters and friends in unusually high temperatures. last time peter, they'll be here in lapi, in central finland. we come here with a question. can international top flight sport survive? the corona, virus global pandemic. find out the answer to that a little later here on out to 0. a hello there. it's a bit of a divided picture across europe, a weather wise over the next few days, with a hot, dry conditions persist across the west, but in the east, it is a cooler wet picture. we've seen those devastating floods, supercross, southern areas of germany and into austria. well, that rain has now ease and the clean up operation is on the way you can see that weather system now pushing its way across the balcony. so we got some really wet weather on the way for bosnia and herzegovina for serbia as well as romania and into southern areas of ukraine to some really torrential downpours and fun distortion. as we go in

we are joint via skype by dennis nash, distinguished professor of epidemiology at city university ofork and the rogers school of public health. if you would describe for us, if you can, because a supposed data and evidence is still being clarified, how effective are any of the vaccines out there against the delta strain of the coronavirus? >> we are still learning a lot about how long these vaccines will remain effective, because the pandemic has only been around for a year and a half. so we are learning as we go. to be sure, it is important to be thinking about the need for boosters and routinely looking at the extent to which these vaccines may result in breakthrough infections, with severe disease. time will tell. but we need to be thinking about it and planning about it because it maybe going forward. but i do agree that it is not the time to be prioritizing a third dose of boosters as much as a more pressing priority that we have, which is ensuring that highly affected countries and regions of the world with little or no access to vaccines can be supplied immediately. speaking t
