for derek williams and the question that could be on your mind if you're waiting for the jap. oh, i have a mild cold. can i get back to needed anyway? great question. you might have been waiting for months for an appointment to get vaccinated and then the day before your nose stops up. well, i can tell you from personal experience with, for example, my kids pediatricians, that in general, if you're feeling even a little under the weather on the day of a shot, and doctors really don't like to vaccinate you for anything in the panoramic. however, the cdc, in the u. s, at least has apparently loosened that rule of thumb somewhat. and germany's health authority conference, the to it agrees both say that if you basically only have the sniffles, then vaccinate hers can go ahead and give you october 19 vaccine. but if you're feeling moderately or more severely el, they say, then you should wait until you recover from whatever you have to receive one. as far as i can tell, doctors and other medical experts appear to draw the line between mild and moderate illness, largely based on the

, people still have questions about the jap, like the following one for science correspondent derek williams. oh, are there any ways to mitigate your chances of developing it from bosis if you're vaccinated with astrazeneca? oh, i'm going to start this answer by saying something i've already said many times before, which is that both trials and hundreds of millions of recipients show the astrazeneca vaccine is highly effective that preventing future infection with covered 19. and the chances of developing the blood plots that have been associated with the vaccine are extremely rare. the exact numbers are kind of hard to interpret. but the european medicines agency says that over the course of both doses, about one recipient and 100000 developed the side effect. so it's a very uncommon occurrence that chance. it's so much smaller than the chance of a serious outcome if you can track over 19, certainly for older people, that there is a very clear benefit and getting the astrazeneca vaccine. because the vaccine induced thrombosis is so rare. we're still learning about it, but we think we figure

time for derek williams and your questions on the corona virus call it some people can still get the virus even after being vaccinated is heard immunity, even possible. questions like this, or why many scientists don't like the term heard immunity because they feel the word immunity implies the point where the pandemic suddenly stops. a lot of them prefer the term heard protection because that feed drives don't make everyone in a population magically immune when enough people have had shot. they just, they just help protect people who are still vulnerable and protection implies ongoing vigilance, which is what pretty much all the experts say we're going to need going forward. and there are a few reasons why heard protection will be very difficult to achieve. not least that as you say, a few people still contract the disease even after full vaccination and can presumably pass it on to others. this phenomenon is called vaccine failure and the person that happens to is known as a breakthrough case. but data from the end of april, from the u. s. has confirmed something that had been repo

more than that, with derek williams and the few questions paul used to be 16172 very and smoothly was one is more contagious. oh, this very into concern which has been designated down under a new naming system recommended by the w. h. ho. it was 1st identified several months ago in india, and it has subsequently been found in many other parts of the world. although final proof is still missing, there's significant evidence that be 16172, or delta is a lot more transmissible than the original version of the virus. and even more contagious than the the alpha barriers that hit some countries hard. last winter. in particular, britain, they are, delta is now causing fresh concern after the country planned to leave lock downs behind on on june 21st. delta is estimated to be call thing around 9 and 10 cases in a new surge in the u. k. were still flying blind in many places when it comes to tracking the spread of specific variance and tying them, for instance, to, to hospitalization. that makes it hard to currently say with any certainty whether the delta variant causes more severe disease. b

over to our science correspondent derek williams. oh, you could 19 vaccines and pretty to the types of corona viruses all depend, nick has turbocharged research into corona viruses. we've learned a huge amount about them in the last 15 frantic months, including in an area called cross reactivity, which involves how the immune system can react to similar structures on the surfaces of different types of viruses. in other words, how your body might not have to learn everything from scratch about a pathogen if that pathogen reminds it of a bug. it encountered in the past fate because it has similar spite proteins and all corona viruses have spikes. theoretically, at least, that means that teaching your immune system to recognise, sorry cubby to spy proteins, could maybe also help it recognise and prevent infection with other corona viruses in the spikes are similar enough. among others. a study published last month by researchers that johns hopkins university in the us shows that the idea isn't far fetched. the researchers looked at the

and as always, derek williams is here to answer them. paul wants to the consequences of not receiving the 2nd due to the vaccine on schedule, or not a told, oh, different vaccines work in different ways. so there isn't really a kind of one size fits all response to this question. but one thing is really clear. that's that, it's definitely a bad idea to skip the 2nd shot of a to dos regimen completely. experts say that's because it plays an essential role in hyping up your immune system to deal with a possible future exposure. the 2nd dose encourages your body to generate particular cells that are able to, to remember, sorry, covey to, even though you might never have had at the 1st dose. initiates the response, and sets the immune system on high alert. while the 2nd helps cement the memory of the pathogen providing more powerful protection that's, that's also likely to be a lot more long term. so although the 1st dose provides some protection, it's really important to follow up with the 2nd one because until you get it, you'll be a lot m

questions still remain about the safety of vaccines for young and old alike. science correspondent derek williams, takes a look at the astrazeneca jap. oh, nice. the answer is in a convex, seen apparently see from age are people. oh, 1st of all, i want to emphasize that the data shows that for the vast majority of people, the astrazeneca cove, it back thing is both safe and reliable. but in extremely rare cases, it has also been linked to the development of potentially dangerous blood clots. there's been a scientific scramble to try to figure out exactly what's going on. and experts now think that in those rare individuals substances produced by the immune system in response to the vaccine can also activate platelets in the blood which, which leads to the clotting because it happens so rarely the statistics aren't conclusive. but women under the age of 50 seem to be affected. most often. that's led national health authorities in some countries with a range of vaccine options to begin recommending the astrazeneca vaccine, primarily to those over the age of 60, where we're links to clotting. we're

he'll turn now his derek williams with you a question on vaccines and variance call the current vaccine scooting selected variance to search. oh, this is another of those internet rumors that gain some traction in the last few weeks, because somehow it sounds like it might be kind of plausible, but it actually isn't to explain why i have to go over some of the basics. again, all viruses evolved randomly over time as they replicate. and the minuscule number of those mutations will prove advantageous. let's say that one of them makes a mutant a lot more transmissible. and humans, while are a potentially dangerous new variance. over time, that variance offspring could start to supplant earlier versions of the virus, simply because the variance spreads to more unprotected people in a population within a short period of time because it's more transmissible. so when you start to look for that very specifically in that population, you see increasing numbers of people getting a search. but that's an effect that can be traced back to the variance ability to spread faster, and people with no immu

very much for being on the show today. pleasure kind of time now for our science. corresponding derek williams. and of your question about how the buyers affects young adults. oh, how does cooper 19 tend to check in the notes? oh, there are 2 this, this multi faceted question that i'd like to talk about. the 1st is of course, the straightforward issue of what the virus does physically to an average young adult as compared to someone who is older and they are the statistics. tell a pretty clear story. cobra 900 mortality increases dramatically with age. let's look at recent data from the us. more than 4 and 5 deaths there have occurred in those over 65 and fewer than one into 100 reported deaths had been and people under 30. but as vaccinations rise among the elderly in countries like the u. s. doctors say that the average age of patients who are being hospitalized with the disease is dropping dramatically and that many of those younger patients will end up with conditions like crippling damage to the lungs or the heart. so although cove at 19 is a lot less likely to kill a young adult, there a

now for our science correspondence, derek williams, the end of your question about how the virus attacks, young adults, paul, who does cooper 191215 minute. there are 2 facets of this, this multifaceted question that i'd like to talk about. the 1st is of course, the straightforward issue of what the virus does physically to an average young adult as compared to someone who is older and they are the statistics. tell a pretty clear story. cobra 1900 mortality, increases dramatically with age. let's look at recent data from the u. s. more than 4 and 5 deaths there have occurred in those over 65 and fewer than one into 100 reported deaths had been and people under 30. but as vaccinations rise among the elderly in countries like the u. s, doctors say that the average age of patients who are being hospitalized with the disease is dropping dramatically and that many of those younger patients will end up with conditions like crippling damage to the lungs or the heart. so although cobra 19 is a lot less likely to kill a young adult, there are still really pressing reasons to get back to native be

and up next is our science correspondent, derek williams, answering your questions about the pandemic. oh, who does could 191215 minute. there are 2 facets this, this multifaceted question that i'd like to talk about. the 1st is of course, the straightforward issue of what the virus does physically to an average young adult as compared to someone who is older and they are the statistics. tell a pretty clear story. coded 1900 mortality, increases dramatically with age. let's look at recent data from the u. s. more than 4 and 5 deaths there have occurred in those over 65 and fewer than one into 100 reported deaths have been and people under 30. but as vaccinations rise among the elderly in countries like the u. s, doctors say that the average age of patients who are being hospitalized with the disease is dropping dramatically and that many of those younger patients will end up with conditions like crippling damage to the lungs or the heart. so, although cobit 19 is a lot less likely to kill a young adult, there are still really pressing reasons to get back to native because getting it c
