Meanwhile, testing of the vaccine of the Oxford University, against the Covid-19 virus has commenced in Britain and it has been given to a sample of one thousand persons. Another 18.5 million pounds will go to Imperial College London as trials accelerate.
The new £18.5 million investment for phase three trials at Imperial was announced by Business Secretary Alok Sharma alongside a £65.5 million new investment in University of Oxford vaccine trials, which Imperial researchers are also supporting.
Currently, more than 100 experimental coronavirus vaccines are in development.
Asked about the progress of the human trials, Hill said he and his team "are not going to give a running commentary" but added, "You can conclude that if the trial is still running - as it certainly is - that would mean there have been no major upsets".
Other vaccines in human trials include those by Moderna Inc, Pfizer Inc and BioNTech SE and China's CanSino Biologics Inc.
"The UK will be first to get access", he added, noting it would also work to ensure the vaccine could be made available "to developing countries at the lowest possible cost".
In a further announcement, Sharma said a global licensing agreement had been finalised between Oxford University and AstraZeneca.
Trump calls Fauci's advice on reopening schools "unacceptable"
Fauci on Tuesday told lawmakers about the possibility of an outbreak in the fall, when college students are slated to start their terms.
The U.K. Vaccine Manufacturing and Innovation Center will be capable of producing 70 million vaccine doses within four to six months of opening its permanent facility at Harwell campus in Oxfordshire, the center said in a statement.
He said another £93m will be put into the building of a vaccine centre - now scheduled to open in summer 2021 - which would be able to produce enough vaccines for the entire United Kingdom population within six months. Health and disease experts say a vaccine that protects people from the new coronavirus could help end the pandemic, but finding one that works and manufacturing enough doses is a huge challenge. But he warned "there are no certainties".
"The UK continues to lead the global response to find a vaccine, and the government is backing our scientists to do this as quickly as possible", he said.
The article is the latest to reflect a change in tone of the prime minister's optimism.
"I understand that people will feel frustrated with some of the new rules", he wrote.
"I recognise what we are now asking is more complex than simply staying at home, but this is a complex problem and we need to trust in the good sense of the British people".
