As it happened: UK regulator approves Covid vaccine use - BBC News
But Boris Johnson warns it will take time for vaccines to roll out, after Pfizer/BioNTech jab is deemed safe on 2 December.
This is the day we have been waiting for.

But it is clear listening to NHS England chief executive Simon Stevens and deputy chief medical officer Professor Jonathan Van Tam that there are some huge logistical challenges from here on in.

First of all, supply. The UK is expecting 800,000 doses in the next few days. But given there are 15 million people over the age of 65 and working in health and care sectors, and all need two doses, it is clear getting more into the country is essential.

Rollout is also difficult. Through a combination of the need to keep the vaccine at ultra cold storage and the fact that the jab comes in batches of 975 that cannot be split up at the moment, immunisation will only be offered from a network of 50 hospitals to start with.

It is why there is still so much hope pinned to the Oxford University vaccine, that regulators are currently reviewing. That does not need to be kept in ultra cold storage and so can be distributed much more easily. Plus there are already millions of doses in the country.

Then there is vaccine hesitancy. Officials have been at pains to stress that despite the vaccine being developed in record time the full testing and regulatory process has been followed.

But the more people don’t come forward, the longer restrictions have to remain in place.

There is a long way to go yet.
