BORIS Johnson today hailed the Covid vaccine as a "biological jiu jitsu" to defeat the "invisible enemy" and get Britain back to normal within months.
The PM addressed the nation this evening on the hopeful vaccine news but urged people to "not get carried away with over optimism" just yet.
Earlier today it was confirmed that Britain is the first country in the world to give a jab the green light.
Experts deemed the Belgium-made vaccine as safe, meaning the rollout to millions of people can now begin.
About 800,000 people will be able to get access to the vaccine from next week, and millions across December.
The PM appeared tonight with NHS England chief executive Simon Stevens and England's deputy chief medical officer Jonathan Van-Tam.
He admitted there were "immense logistical challenges" with delivering the vaccine - and that the NHS would contact people in the order it would be rolled out.
And he said there was now no longer just a "hope" that things could get back to normal.
He said tonight: "We are no longer resting on the mere hope we can return ot normal but rather the sure and certain knowledge that we will succeed and reclaim our lives and all the things about our lives that we love."
Boris said "we have to fight on" and continue with the tougher Tier rules until the vaccine can get to those who need it.
NHS boss Simon Stevens said they were gearing up for the biggest vaccination programme in the history of the health service and they were "raring to go".
Deputy Chief Medical Officer Jonathan Van Tam revealed today he was "quite emotional" at this morning's vaccine news.
But he warned that everyone must be "patient and realistic" about how the jab is rolled out.
