After they took on the big money of wall street. And get your skates on 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 that 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. This weekend, British Nationals in hong kong will be able to apply for a 5 year uk visa in a move that has angered china and could see diplomatic repercussions. The visa is being introduced after china imposed a security law on hong kong. Paper applications will be accepted from sunday and a Smartphone App coming in a few weeks will improve privacy and security. Speaking to the bbc, the british Home Secretary priti patel told the bbc it was absolutely vital to give applicants some protection. Heres our Diplomatic Correspondent james landale. After months of protests from pro democracy campaigners, Beijing Last Year imposed a tough new security law on hong kong. Britain said this deal was broken as they tried britain said this brokered was agreed with china as they tried to protect the so ministers are offering a way out for those British Nationals who want it. So for us in particular, weve made a promise to the people of hong kong when it comes to safeguarding and preserving their liberties and freedoms, particularly as they are being restricted by the chinese government, and this is one of a kind, a bespoke visa route to provide freedom, safety, security. So, whos eligible for the new visa . Its open to anyone registered with British National overseas or 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. In the process, they can use schools and the health service, but cant claim welfare benefits. Crucially, people can apply discreetly via a Smartphone App, rather than go in person to a visa office, where they could be identified by the authorities. The digitalisation of this process will obviously give people assurity, safeguards and protection when they make these applications, because 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. Vital for those individuals that go througho this process. Applicants have to show they have enough cash to survive the six months. Theres a £3,000 health surcharge. So the government estimates only about 300,000 bnos 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, insisted on acting wilfully, repeatedly hyped the issue of British International passports, interfered of British National passports, interfered in hong kong affairs, and interfered in chinas internal affairs. It will lift a rock only to drop it on 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. Big questions are being asked about how the us Stock Market Works after individual investors were stopped from Buying Shares after big losses for Wall Street Traders. Shares in gamestop, a video game retailer, soared after a group of private investors used online chat forums to drive up their price. Paul hawkins reports this is a story of david versus goliath, the Amateur Online Investor beating the Big Traditional Wall Street traders. At the centre of it, gamestop, a struggling American Retailer Selling dvds and video games. A number of the Wall Street Traders picked up on its problems and bet money that its share price would fall, known in the business as shorting a stock. Only for this particular stock, amateur investors swapping tips on the social media site reddit saw it as an opportunity. They bought shares, which actually drove up the price by 700 . So the Wall Street Traders, which act for hedge funds, lost money potentially billions of dollars while the amateur investors made money. But on thursday, the main platforms small investors used to buy up the stocks, like robinhood, stopped them from buying more shares. The reddit investors, unsurprisingly, werent happy. They want the Hedge Fund Guys to win, they dont want the common man brokers, they dont want us to win. They said that i could only sell my amc stock, they said only sell my nokia stock, but i couldnt buy more this morning. Thats crazy how is that a free market in any way . Thats not a free market, that sounds like communism these are dirty, dirty people they deserve jail time money they will be able to repay the money they can pay millions of Dollars Worth of fines this isnt about money, this is aboutjail time, prison they should go to jail accusations like that will hurt platforms like robinhood, who have helped to democratise the stock market. Its co founder said the firm had taken its decision based on regulatory requirements and limited buys of the restricted stocks would be available on friday. The restricted stocks would be allowed from friday. You have a generation that feels it is their time, you have new weapons of influence, new trading platforms, and a lot of people at home with stimulus in their pocket and phones and access to trading. It all kind of spells a cocktail of volatility. Even american politicians are unusually united over their response, with the incoming chair of the Banking Committee promising to look into how the Stock Market Works. Bell rings. Everyone loves the story of a plucky underdog but a black eye for wall street may have repercussions for the rest of us. To cover their losses, the big investors may need to sell their shares in other things like pension funds, and that means their share prices fall. Thats not good for the people who rely on them. Paul hawkins, bbc news. Well, earlier, ispoke to Jaime Rogozinski who created the reddit forum that spearheaded the campaign to drive up gamestop shares in a battle against hedge fund short sellers. I asked him if he ever envisioned his previous platform would be used in such a way. First off, thank you for having me and no, absolutely not. I think this was beyond my wildest imagination. This has gone so far, so quick, and its 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, from what i understand, so they are trying to figure out a way to contain this. I dont know how they can do it. There is no precedent. All of the rules that have been written, all the examples historically, nothing comes close to Something Like this. I wish them luck, thats my advice . We should make it clear even though you founded the wallstreetbets forum, you dont run it, and it must be something of a relief, given the decisions the moderators are having to make of staying within the law, for example, must be a really tricky line to tread. What do you think they should do . It is a tricky line to read. When i was a moderator like this, nothing happened. We had a situation that came close to this and it did have a little bit of press and i stopped it, just because i didnt want to push the language. There is a lot of grey area in this language. I didnt feel like taking the coin flip to see exactly where it would land. But the moderators that are currently on there, they clearly 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. One thing is for sure, i would be concerned if i would wonder myself what the optics would be like if they themselves were involved in some of these trades, given they can actually control or influence the dialogue that takes place on the forum. Some users on that chat forum are very angry that platforms like robinhood, for amateur traders and investors, have suspended Buying Shares and following that decision, the share price has fallen quite dramatically. What is your reaction to some brokers saying no, stop. You cant trade any more. As well they should be upset, because the brokers are causing some of these people to lose money. They are used to making these quick trades when they come in and out in the moment where theyre able to get that theyre stuck, i dont know exactly what the mechanics of this block looks like, but they have a right to be angry. I question why the brokers did this. Very specifically robinhood because we have a different demographic, they have their the company has a different profile, they go after certain customers and users, they dont mind getting into hot water. It doesnt make any sense for them to voluntarily taking take away the ability for their users. It makes sense for some other brokers. Im convinced there are other forces at play other than waking up this morning, because they themselves are causing volatility. Well, now we see what happens when the brokers cut off the switch. Its complicated. Jaime rogozinski. Stay with us on bbc news. Still to come russian Opposition LeaderAlexei Navalny loses his appeal forfreedom, but says his detention wont intimidate him.

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. The exact details on that, though, will change. Well keep you updated. Today, though, is a fairly quiet one. There will be plenty of cloud around and some showers. A cold start, too, across parts of scotland. Here, were seeing snow throughout the night, temperatures low enough for some ice and made to feel colder by strong winds. 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.
