Health Secretary Matt Hancock has revealed who the first people to get the coronavirus vaccine will be.
In today's daily briefing Mr Hancock outlined the progress of the vaccine.
He confirmed the imperial vaccine was in the first phase of human trials and that the Oxford vaccine was being manufactured, ahead of clinical approval.
Mr Hancock said: "We are building a stockpile, so it'll be ready should the science come off."
He also explained who the first people would be to get the vaccine.
He said: "We will be guided by the clinical science and they recommend priority vaccination for two groups: frontline health and social care workers and those at increased risk of serious disease and death from coronavirus."
That would include the over-50s and those with heart and kidney disease.
It could also potentially include other groups that might be vulnerable, such as those from ethnic minority backgrounds.
He continued: "As we learn more about the virus we will continue to take into account which groups may be particularly vulnerable, including, for example, those from ethnic minority backgrounds so that we can protect the most at risk first, should a vaccine become available, and get this country back on our feet as soon as we possibly can.
"We are throwing everything at getting the vaccine as fast as possible."
The Health Secretary also defended the decision to abandon developing the NHSX app in favour of joining forces with the Apple and Google project.
At the Downing Street press conference he said testing on the Isle of Wight uncovered a "technical barrier".
He said: "We found that our app works well on Android devices but Apple software prevents iPhones being used effectively for contact tracing unless you are using Apple's own technology."
He said that the NHSX app was better at measuring distance than the Google/Apple model.
He said: "As it stands, our app won't work because Apple won't change their system, but it can measure distance.
"And their app can't measure distance well enough to a standard that we are satisfied with."
