and would you listen cafferty to what they have to say so we will get on with rolling out the vaccine program and to answer your question absolutely i don't think that anything i have seen leads me to suppose that we would have to change the road map deviate from the road map in any way let's look at the science behind this if we can laurence as young as if they're all or just an professor of molecular oncology one of universities that medical school is talking to us from near the u.k. so 2nd biggest city bamiyan welcome to day w so what we've heard from the a.m.a. is a possible link between the astra zeneca drug and these rare blood clotting disorders we kind of knew that because that's where we were before we thought there was a link and now they're saying there's a possible link can you explain to us how we have moved closer to knowing that there is a link between taking this and potentially getting this condition you know and this is just mounting evidence really that there is an increased. association.

an association between. the astra zeneca got seen in these rare blood clots what we don't know still is whether that is cool so you just have to get more data what you've got is a very very rarely very very rare side effect the evidence is slowly but surely firming up across europe and the u.k. and the possibility is becoming stronger all the while that there is an association albeit very very rare. they theorize that this could be i mean mune response about vaccination could you explain that to us please. yeah because there's a this is a very strange form and that's what form of coursing and that's what makes it a bit old because what you're seeing is increased blood clotting but the cells are actually responsible for supporting blood. alone so you've got this low platelet count and that's sometimes associated with an immune response so sometimes the body

your body can mount a bizarre very rare immune response against the platelets themselves your own blood cells and this is what makes this a bit peculiar and a bit suspicious because it looks like there is an immune response going on in a few individuals that precipitates and leads to this rare form of clotting and what we don't know he's are there any other risk factors associated with that but i think it's because of the rarity of this very specific form of blood clotting that makes us really suspicious and so and that that there is something to do with an abnormal response to the vaccine or possibly to people who've been vaccinated who then go on very soon after vaccination to get kovan has you know coded itself is associated with blood clotting and this is a type of thing you can only sort out when you've got larger numbers and the numbers of cases at the moment are far too small so what this is all about is just beat reporters. today we also heard from the u.k.'s vaccine advisory body and they

have very very medical regulators they fame took on a step further by saying it's preferable for people under 30 to have an alternative to the astra zeneca vaccine what's behind that. if you look very carefully at the data and the balance of risk so what you look at it looked at for every age group is the balance of risk of getting this very rare form of blood clotting against the risk of getting severe disease and hospitalizations and what you find is that balance the risk is more favorable for older people because we know older people are much more susceptible to the severe consequences of coping and younger people actually this is you know are relatively protected and when they get over it they don't tend to get as sick and certainly you the death rate younger people is much lower so they've made a cut they've come to a conclusion because of that risk benefit analysis if you like that it's probably

a for to protect the under thirty's from the possible consequences of this astra zeneca vaccine and provide them when we come around to vaccinating that group with a lot early to vaccine thank you so much for that explanation i have professor lawrence s. young from the university of worth and some other developments and the covert 19 pandemic a study by the world health organization in china has provided no credible answer to how the pandemic began and the international group of scientists says more rigorous investigations are needed with or without beijing's involvement iran has recorded its highest number of new infections for a 2nd day in a row nearly 21000 on wednesday the search has triggered new restrictions on movement in major cities ahead of the persian new year and morocco is nightly curfew will remain in place ensuring the muslim holy month of ramadan when people gather after breaking their fast at sunset is part of government action to counter

new variant. brazil has reported more than 4000 new daily deaths from kovac 19 for the 1st time the country's pandemic death toll is now approaching 340000 but 2nd only to the united states experts say the latest search has been caused by a local variant of the virus which has pushed the health care system to breaking point despite this right wing president jaya also narrow as opposed lock down measures as damaging to the economy but many of the country's poorest crying out for help saying that the government's pandemic response has failed them and that without more help they risk going hungry. these protesters a sending a message to their government brazil is hungry. here and sao paulo's largest para's openness residents say emergency aid doesn't go far enough i mean they say that my fear is that my daughters will go hungry one of them still under 18. this

is also my granddaughter and i think to myself well they go hungry and the like but far from up until december the brazilian government provided those in need with around $1000.00 euros per month in 8 community centers like this one have been offering free meals but donations have dropped. presidential year both scenarios administration is once again offering help but a more modest amount a community movement known as g. 10 is demanding more. for similar thought since i'm going to have the emergency a little of $23.00 euros is enough to buy a domestic gas cylinder 5 kilograms of rice and one kilogram of the us a family can't survive a month on that it's shameful brazil is a rich country and letting its population go hungry and the pandemic is still out of control brazil is a country in crisis and there's not much light on the horizon. a more stories
