The argument in europe about the distribution of coronavirus vaccines has intensified with the authorities in belgium investigating a Production Site owned by astrazeneca. Brussels wants to know why the Pharmaceutical Company wont be able to deliver all of the doses it promised. The eu has called for some of the vaccines made in the uk to be diverted and warned it could resort to legal action. Our medical editor fergus walsh reports. Once again, science has triumphed in the fight against coronavirus. The Us Firm Novavax has released results of its british trial showing the first proven efficacy against the new, more contagious uk variant. There were more than 15,000 volunteers on the trail throughout the uk. Over half the cases of covid recorded were the result of the new variant. The results showed the vaccine was 95 effective against the original covid strain and over 85 effective against the new uk variant, giving an overall efficacy of 89 . The former head of the uk Vaccine Task Force said that in a separate trial in south africa, the vaccine had shown it protected against the variant of concern there. Its a fantastic result because it shows the novavax vaccine is effective against both the uk variant as well as the South African Variant and has shown phenomenal efficacy, and its made in teesside so not only have we trialled the vaccine to show its safe and effective but we are also making it too, so well be able to save lives in the uk. Meanwhile, the biggest Immunisation Drive in the history of the nhs just keeps growing. This Supermarket Pharmacy near birmingham started Offering Covid Jabs today to the over 75s, one of more than m00 vaccination sites in england alone. What a contrast in madrid, where supplies of vaccine have all but dried up. The spanish capital has cancelled all appointments for around two weeks. The eu were slow off the mark in ordering vaccine, and now wants some of the uks supply of astrazeneca doses. In may, the uk government was the first to sign a deal with astrazeneca for 100 million doses of its covid vaccine. It wasnt until august three months later that the European Union signed an agreement for up to 400 million doses. Last month, the uks mhra became the first regulator in the world to approve the Oxford Astrazeneca jab. Tomorrow, the European Medicines Agency is meeting and is expected to approve the vaccine, but for the moment, it remains unlicensed in the eu. The astrazeneca vaccine is grown in bioreactors. Ive seen how complex the process is at this site in oxford. By contrast, there have been poor yields at the main european site in belgium. The eu is threatening legal action to force astrazeneca to hand over some doses made here. We can and will get doses of the vaccine from the series of plants which are mentioned in the contract, and therefore, also including those in the united kingdom. And now another twist germanys Vaccine Committee has said the Astrazeneca Jab should, for now, only be given to people under 65 years old. It cited insufficient data over its efficacy in older people. The government here firmly rejects that. Our own authorities have made it very clear that they think the Oxford Astrazeneca vaccine is very good and efficacious. They think that it is effective across all age groups and provides a good immune response across all age groups. There is limited evidence on how well the Astrazeneca Vaccine Works in the over 65s, but leading scientists here say they are confident it will give strong protection. France, portugaland germany arejust some of the eu Member States struggling to get hold of enough vaccine supplies. Vaccinations are having to be postponed before the roll out has really begun. Germanys Health Minister says the countrys facing a shortage well into april and warned of at least 10 tough weeks ahead. Jenny hill reports on the difficulties germany is facing. A waiting room without any patients. A Vaccination Centre without any vaccine. Germany relied on the eu to place its orders, a decision which may have come at a cost. Translation we really feel it here. People keep asking us why we havent been vaccinated yet. At the end of the day, these are political decisions which i have to accept, but i am looking forward to the time when we have enough vaccine and can get on with it. No tourists now for city guide teresia. Immunity would bring life back to marburgs streets, restart the german economy. But just 2 of the population have had their first dose of the vaccine so far. Even so, she tells us, it was right for the eu to order vaccine together. If everyone in germany gets vaccinated but not people in the countries around it, then the plague comes back over the border. If we do it, we should do it together, even if we have to wait. Months of restrictions here appear to be paying off. Germanys Infection Rates are now falling, but theres real concern about the impact of new variants, like those discovered in britain or south africa. And while the German Government has pledged to offer every Citizen A Vaccination by the end of the summer, thats starting to look like a very hard promise to keep. So far, germanys relied on the Pfizer Biontech vaccine. The manufacturer has announced delays. Though a new Production Site here in marburg is expected to boost output. Supplies, too, are expected from moderna, and, if approved and on time, astrazeneca, though germany may only give it to the under 65s. We want to know what took so long. Which Member States were rather reluctant in ordering together and which Member States said, hey, lets go forward. I think it would have been a great sign from germany, as the economically strongest member state, to say, hey, if its a question of money, we willjust say 10 Billion Euros on the table to get things going. Marburgs Vaccination Centre, closed now, though they expect supplies to arrive next week. No ones quite sure what happens after that, and even the German Government warned today the next ten weeks will be tough. Jenny hill, bbc news, marburg. In the last couple of hours, the uk government has announced another vaccine, novo vax, has been successful in trials and will be produced in the uk. So its a good time to ask if were now looking at Vaccine Nationalism, wther countries are at Vaccine Nationalism, where countries are prioritising their own Vaccine Needs . Im joined by krishna oodaya koomar, the founding director of the Duke Global Health innovation center, which studies Global Health and policy. He gave me his thoughts on the astrazeneca row. I think what we are seeing now is a microcosm of what it looks like Around The World and in some cases, just to put this in perspective, we are talking about the eu in the uk about how many days or how many weeks it may be that we should keep in mind that most of the world we are talking about, months to years that theyre going to be waiting and so, while the eu in the uk have significant concerns rightly so about how quickly they can vaccinate, theres still taking doses and while we talk about the need for global equity, we are still seeing signs of more Vaccine Nationalism or regionalism here. Nationalism or regionalism here,. , nationalism or regionalism here. ,. ,. , here. So, we saw the situation in germany here. So, we saw the situation in germany with here. So, we saw the situation in germany with vaccination i in germany with Vaccination Centres being empty and this problematic next ten weeks, is it fair for problematic next ten weeks, is it fairfor germany to problematic next ten weeks, is it fair for germany to be asking astrazeneca to move vaccines from the uk to germany . Vaccines from the uk to german . ~ , germany . Yeah, i think every country in germany . Yeah, i think every country in the germany . Yeah, i think every country in the region germany . Yeah, i think every country in the region is germany . Yeah, i think every country in the region is trying | country in the region is trying to do anything under its power. There is hope that we can use multilateral platforms in order to bring more substance to conversation that focuses more on Global Access equity, but we know that every government feels like they have a responsibility to do what is best for their own residence and so the tension that we are seeing now is going to continue to worsen over time, especially as we start to see more unexpected delays in terms of manufacturing and production of these really critical vaccines. So, just briefly if you would, if that tension is increasing, and organisations like the who that are behind this, do they still have a place here when it comes to distributing a global roll out of vaccine . I do comes to distributing a global rollout of vaccine . Rollout of vaccine . I do think there is a rollout of vaccine . I do think there is a very rollout of vaccine . I do think there is a very strong rollout of vaccine . I do think there is a very strong place, | there is a very strong place, but theyre not going to be the only Decision Makers on the table. If the did not have them for example, it would be the wild west with everybody for themselves. We would have a platform to build from and at the same time, the hope really is the short term that more and more vaccines are shown to have efficacy and safety and that we continue to ramp up manufacturing because we know that the supply is nowhere near with the demand in need are in the short and week by week, month by month, the hope is that we will see a bit of easing as the Supply IncreasesAround The World. Easing as the Supply IncreasesAround The World. Thank you for talkin Around The World. Thank you for talking us Around The World. Thank you for talking us through Around The World.
