 Mae'r iawn arfer o'r Fforddon Mawthau uwch i Cyfliad Acurau Newydd a'r gwходio cyflawn gennym i ddech chi'n cynhyrchu Cyfoedd. Mae'n mynd i ddweud o'u cynhyrchu newydd yn gyflwyno cyddiadau, felly mae'n cyddiadau gyda y virus yn y gyrtain. Mae'n credu cyflawn cael cyflawn yn gyflei'n cyflawn. ac byddwch yn unigwysodd yr unigwysodd yn ei wneud i'w wneud yn ff BMW, oherwydd meddwl y dod iddo i'w ffaisio o гweithiwch ar gyfer y drafodaeth ym Mwlleunio. Yma, mae'r unigwysodd yn y wneud ei wneud yn ff without a bod ni'n bwysig ar y rai. Mae'n gweithio rhywbeth ei wneud eu busg ei wneud i'w wneud yn y rai. ond we have to have three controls to show that the virus that we're using will actually cause disease. So we hope and expect that the animals that have been vaccinated will either show no clinical signs at all, they'll be fully protected, or they'll show very mild clinical signs. Mae'r anodd yn cael ei wneud yn ystod, ydych yn ystod yn sgwrn ffordd o'i ffordd o'r ddymarth. Ond rwy'n dechrau i'r holl yn ddim yn ddim yn ystod, ac rwy'n credu i chi allan o'r holl yma, ac mae'r cyfnodd ar y cyfnodd yn cyfnodd o'i ddefnyddio'n clynyddiad. Ond mae'r ddechrau ar gyfer 50 ynghylch ar fynd i'r wneud, Ac mae'n gweithio argymdeiliadau y f journalistiaid o'r phir yma iawn, oherwydd oeddo'n gwneud y ffaxin i gael y同lliannau byddiw'r cyhoeddnod cyflwyno eich cheerfyrr yn ei ffyrus gweithio. Onw'n dda wedi cael ei gael gwybodaeth iawn o'r ffaxin i beth yn ymddugwch, mae'n cyhoedd iawn i'r ffaxin iawn. Mae gwneud ychydig y ffrifeniad a siaradau gweithio, a gallwn ni'n deistru i'r mawr gwneud y cyd-20 o gyfrifio, a wneud yn cael cyd-20 o gyfrifio a wneud yn cael cyfrifio i'r mawr gwneud i'w mynd i'w rhai ayn ni'n gwneud i'w mewn wedi'i boi atiwn gyfrifio a'r penedigol, ac mae'r gyfrifio o'r mo graspau am gyfrifio ar 8-1. Felly rydyn ni'n gyd-dyl i'w mynd i'w mynd i'w ar aceddol i'w gwneudio i'w pryd-1. If the vaccine is protective, then we can give advice that it can be used in the field in the countries that are suffering from the disease. If it isn't protective, then we have to go and find a different vaccine formulation. But that's very important information because then we're not advising the companies or governments to use a vaccine that we know will not provide full protection in the field. So both results are very important. So that if this trial is successful, it can go straight into production into growth in 10,000 litre vessels to make thousands and millions of doses of vaccine. And so theoretically there could be a usable vaccine on the market in probably six weeks to two months. If the trial isn't successful, then we have to go back to the drawing board and go back to looking at other isolates of virus we've taken from the field. And then we have to get them to grow in tissue culture. It could be another three to four months at least before we're in the position to have another virus that can be made into a vaccine to test again. So these studies, because of the nature of the disease, are monitored very closely. As a minimum, the animal staff will come in here at least twice a day to make sure to formally examine the animals to look at their clinical science. We have highly trained staff who have a huge amount of experience of this disease and know the process that the animals go through in the run up to them showing disease. So they're very familiar with the early clinical science and that's very important that we can control the severity of infection closely. Of course there's always the question of you're deliberately infecting animals with a virus that's going to cause disease. And then of course we have to kill the animals at the end of that study because they can't be released back onto the farm because they have been infected and could carry foot and mouth disease. That could have a devastating effect on the UK's agricultural system. But if you think we've gone through extensive laboratory studies to choose what we believe is a vaccine that will protect these animals with foot and mouth disease, and then we're using 18 animals to test a vaccine that will be used to protect millions of animals and to stop them getting disease. So even though I don't think any of us likes to carry out these types of studies, they're essential if we're going to protect the larger livestock population around the world.
