The new Lockdown Craze sweeping the globe. Welcome to our viewers on pbs in america and around the globe. Major trials of a new vaccine have shown its effective against some new variants of covid 19, helping to reduce fears that they might prove resistant. Novavax is an american jab but its being produced in the uk. Its also easier to roll out than some previous vaccines since it doesnt need to be kept at ultra low temperatures. The news came amid a deepening row between another vaccine maker, astrazeneca, and the European Union over shortages. 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 Taskforce said that in a separate trial in south africa, the vaccine had showed 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 that its safe and effective but were 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 1,400 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 want 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 theres another twist germanys Vaccine Committee has said the Astrazeneca Jab should, for now, not be given to people aged 65 and above. It cited insufficient evidence in how effective it is 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. Fergus walsh, bbc news. Earlier, i spoke to vaccinologist dr peter hotez from the Baylor College of medicine in houston. He welcomed Novavax Trial results. It looks like its going to be another important vaccine. So now weve got the two mrna vaccines, we have the Astrazeneca Oxford vaccine, we will hear thej j vaccine soon, and the novavax, we have a recombinant and protein vaccine. And some people may ask why you need all these vaccines, well, theres limits in the capacity for production for any one of them, so the more we have the more shots on goal, the better globally we have a chance to beat this pandemic. And then in terms of the variants, where are we up to with knowing how much protection existing vaccines will provide against, for example, the variant that has been found in brazil and the one that has been found in south africa . Yeah, the south african one is really worrying people because we are seeing diminished protection with both the pfizer and Moderna Mrna Vaccine and we heard about the result today from the novavax vaccine which probably gives the highest virus neutralising antibody titres, which is kind of a Surrogate Marker or the protection of any of the vaccines and that is only doing 50 60 . So the real worry im thinking about, because we also have a recombinant protein vaccine and we are looking at how to modify or add the South African Variant is how quickly we can vaccinate the world in order to raise ahead of the South African Variant. It is putting enormous and everybody right now. The other announcement that came today was we know the virus variant, the South African Variant, arose in North Carolina in the eastern united states. So this is going to be a very stressful time, vaccinating with the existing vaccines, to slow transmission and prevent the widespread emergence of the south African Vaccine while the Vaccine Developers now start adding efforts to specifically tailor vaccines specifically for south africa. And what you think, you mentioned the us, that is where you are, what you think the strategy that should be in order to most effectively use the vaccines that are now available . Well, you know, when the Biden Administration got up they had to learn a lot. They didnt have a lot of advanced time and they put a plan in place that sounded reasonable, but now with the new variants are rising quickly, the centers for Disease Control are saying the uk variant may be significant by the spring and now the South African Variant. So we are going to have to make adjustments and i have a piece that come out in the Washington Post this week that basically said the plans to do this by the fall may no longer be valid. We have got to find a way to do this by late spring or summer and people say, fine, how do you do that . And i believe a of it may depend on having the Astrazeneca 0xford vaccine as soon as possible. Dr peter hotez speaking to me a short time ago. Lets get some of the days other news. The speaker of the us house of representatives, nancy pelosi, has said that members face a Security Threat from within congress itself. Us media is reporting that a republican member of the house, Marjorie Taylor greene, has expressed support for executing democrats in posts online, though she has subsequently said the posts do not represent her views. Officials in the town of gainesville in the us State Of Georgia say a leak of Liquid Nitrogen at a Poultry Plant has killed six people. Firefighters said around 130 workers from the Prime Pak Foods Plant were evacuated. There are reports that several firefighters were injured. The white house has said its outraged by the pakistani supreme courts decision to release four men convicted of involvement in the killing of an american journalist, daniel pearl.

This weekend, British Nationals in hong kong will be able to apply for a uk visa using a Smart Phone App to protect their privacy and security. The british home secretary, priti patel, told the bbc it was absolutely vital to give applicants some protection. The new visa comes into force on sunday. Its being introduced after china imposed a security law on hong kong. Heres our diplomatic correspondent, James Landale after months of protests from pro democracy campaigners, Beijing Last Year imposed tough new security laws. Britain said this deal was broken as they tried to protect the territories autonomy. So ministers are offering a way out for those British Nationals who want it. So for us in particular, youve made a promise to the people of hong kong when it comes to safeguarding and preserving liberties and freedoms. Particularly as they are being restricted by the Chinese Government and this is one of a kind, they spoke to provide freedoms, safety, security. So whos eligible for the new visa . Its open to anyone registered with British National overseas 0r bno status before 1997 when hong kong was handed over to china. It also includes children, partners, and dependent relatives. That potentially includes up to 5. 2 million hong kong citizens. Thats more than two thirds of the entire population. So what does the visa do . Well, it gives bnos the right to live, study and work for up to five years. They can then apply to settle permanently with the chance of citizenship after six years, they can use schools, the health service, but cannot claim welfare benefits. Crucially, people can apply discreetly via a smartphone app, rather than going in person to a visa office where they could be identified by the authorities. The digitalisation of this process will obviously give people safeguards and protection and when they make these applications, clearly the environment is changing in hong kong and safeguarding the individuals freedoms, liberties and securities is absolutely vital for those individuals who go to this process. There are hurdles. Applicants have to show they have enough cash to survive the six months and theres a £3,000 health surcharge. Anywhere between 300,000 will come to britain over the next five years. China is furious and has already threatened retaliation. Translation the british side has violated its promises and has repeatedly hyped the issue of British International passports, interfered in Hong Kong Affairs and interfered in china and internal affairs. It will drop at its own feet in the end. But the British Government is determined to offer a lifeline to those in hong kong that it believes it has a moral duty to help. James landale, bbc news.

Did you ever foresee the plat form being used like this . First off, thank you for having me and no, absolutely not. I think this was beyond my wildest imagination, this is gone so far so quick, and its fascinating to watch. The regulators fascinating to watch. The regulators are fascinating to watch. The regulators are concerned about the volatility, not only of the shares but the wider impact its having on the market. What would you advise them to do . What do you think their next move should be as regulators . As well they should be worried, this market is doing some strange things but i dont envy their position. They have an impossible task. They are trying to protect innocent investors. There is surely going to be some innocent investors but a lot of the people involved with these are taking these really risky trades using stock options, not even stocks, which are required sometimes for these regulations as under that end, so they are trying to figure out a way to contain this. I dont know how they can do it. There is no resident. All of the examples, nothing comes close to Something Like this. I wish them what, thats my advice . We should make it clear, even though you found the forum, you dont run it, and it must be something of a relief, given the decisions moderators are having to make of staying within the law must be a really tricky light.

There is a lot of grey area in this language. I didnt feel like taking the coin flip to see where it would land. But the moderators that are currently on now, they have are currently on now, they have a different philosophy. I dont have any advice for them because theyve already taken the actions they have taken. I dont envy their position either because they are obviously in the spotlight.

I question why the brokers did this. Maybe specifically robin hood because we have a different demographic. The company has a different profile, they go up to certain customers and users. They dont mind getting into hot water. Except voluntarily taking away the ability for their users. It makes sense for some other brokers. Im convinced there are other forces at play because they themselves are causing volatility, well now we see what happens when the brokers cut off the switch. Its complicated. Cut off the switch.

Iv e ive only just mastered ive onlyjust mastered the whole running things, never mind rollerskates. You can reach me on the whole team on social media. On twitter, im benmbland. Hello there. It can be a fine line between rain and snow here in the uk, and the battle lines are certainly drawn over the next few days. Cold air to the north east of us, milderairto the south and west. On that dividing line, which this weekend pushes its way southwards, this is where we could see that rain snow mix, particularly on saturday. This swirl of winds, a developing Weather System, developing area of low pressure, which pushes into that cold air. And on the Weather Fronts that reach the cold air, we could see some significant snow, parts of wales and parts of Southern England especially. Stronger but milder winds across the south as well. Here, well see some early showers across wales, south west england, pushing across the southern half of england and wales. The odd rumble of thunder possible, Brightening Up later. Some mist and fog around the midlands, Northern England to begin with, Brightening Up but then clouding over as rain and eventually a little bit of hill sleet pushes in. Brightening up, too, to parts of the northern half of scotland, compared with what weve seen. Patchy rain and sleet into southern areas as we finish the day and that north south contrast, as far as temperatures. The colder air on the move further southwards, then, as we go through friday night into saturday, and as this Weather Front approaches off the atlantic, initially, rain, and quite a bit of rain could cause some minorflooding towards the south west and across some southern counties. Temperatures here holding up, but a greater chance of some frost. 7 to start the weekend in northern scotland. But as that rain pushes into the cold air, the potential for not only some heavy snow, but with strong winds, Blizzards Over The Welsh hills. At the moment, it looks like wales, into parts of the midlands, maybe South East England could see some snow. How much, of course, that will depend on exactly where that Weather Front will lie. Well keep you updated on that, and certainly worth watching the forecast. The further north you are, it does look like it should be a dry, bright, cold start to the weekend, but that frost will return with a vengeance as we go through saturday night into sunday. And as one Weather System clears, another one will be approaching, so whilst it will be a frosty, bright and, in places, icy start to sunday, this next Weather System, bringing rain initially to south western areas, could turn to snow as it pushes across england, wales and Northern Ireland later in the day. Keep checking your forecast here, though, on bbc news. Bye for now. This is bbc news. The headlines trials of a new covid 19 vaccine have shown its more than 89 effective against coronavirus. The jab, developed by the American Firm novavax, also offers protection against the variants discovered in the uk and south africa.
