The NHS is preparing to introduce a coronavirus vaccine soon after Christmas, the Sunday Times report.
Reports say trials have shown it will cut infections and save lives, Jonathan Van-Tam, the deputy chief medical officer, has privately revealed.
He told MPs last week that stage three trials of the vaccine created at Oxford University and is manufactured by AstraZeneca mean a mass rollout is on the horizon as early as December.
Thousands of NHS staff are to undergo training to administer a vaccine before the end of the year, the Sunday Times says.
