With the virus accelerating as you just heard there, in many parts of the world countries are racing to find a safe vaccine. The British Government has secured early access to some 90 million doses of vaccines in development. Lets bring in kate bing ham, chair woman of the British Governments Coronavirus Task force. Joining me now. Thanks for coming on. Good morning to you. Good morning. You are head of the task force. You report directly to the Prime Minister. How promising are the vaccines that youre looking to secure that are being researched right now . Thank you, natalie. So the answer is that i think the different vaccines that are being developed are quite promising. Weve secured rights to the four different main types of vaccine but the real answer is we dont know whether or not any of these vaccines are going to work. Weve taken a view that we need to have a portfolio approach with different vaccine modalities so that we can be sure that if any vaccine works, we will have rights to it. But at this moment we dont know whether any vaccine will work. You have to be out ahead of it. How important is it to coordinate this . You have to figure out how to get tens of millions of vaccines and from where . Whats the number youre expecting and how are you going about it . So we are expecting to build a portfolio of maybe 8, maybe 10, up to maybe up to 10 vaccines across the different modalities and the way were going about it is to bring in a small team of highly expert vaccine specialists who are scouring the world, reviewing the data wherever its come from to then identify which are the most promising and then we pick up the phone and we talk to them directly and talk about how we in the u. K. Can contribute to the development and manufacturing of their vaccine so that we can secure rights not just for the u. K. But to ensure there is Global Distribution of these vaccines so that we can ensure we can end this Global Pandemic as soon as possible. When and if it happens, who would get vaccinated first . That would be dependent on each individual countrys policies, but in the u. K. We have a committee called the joint committee of vaccinations and immunization and they give guidance to the government. In our case the priority groups to be vaccinated include the elderly, which is anyone over the age of 50, it includes people between 18 and 50 with comorbidities such as type two diabetes or heart disease. It includes ethnic minorities and front line workers. Those are the target populations in the u. K. But i imagine each country will have somewhat different definitions. Its likely to include those different cohorts. As you reach out around the world to try to secure vaccines, is there an issue with nationalism right now . How do you avoid a potential problem of, say, every country in it for themselves, a vaccine grab . So i think there is an issue or potential issue with vaccine nationalism. I dont think its unexpected for them to want to protect their Vulnerable People in the countries. Ive been struck by the level of coordination between countries so we can establish a global pool of vaccines so that we can basically provide at least 2 billion doses of vaccine around the world so we can end the acute phase of the pandemic by the end of next year. That sounds really good. Well end on that note. Its got to be all in. Its a global effort. Appreciate your efforts and what youre doing, kate bing ham, we appreciate your efforts. Thank you. Thank you. Meantime, Health Experts say it again and again. Do not gather in large crowds. It is too risky right now when this virus is running rampant. And those same doctors get very worried when they see people, especially young people, ignoring their guidance. For more about this, heres brian todd in washington for us.

This is no time for anyone to be vying for induction into the knucklehead hall of fame. Reporter state Health Officials say theyre worried that the house party could lead to a new cluster of coronavirus cases. How bad could that cluster get .
