Covid: PM says England's four-week lockdown will make 'real impact' - BBC News
Boris Johnson stresses the "stay at home" message on 5 November - the first day of England's second lockdown.
In the second question from the public, the PM is asked what consideration has been given to limited vaccine success and how we live with Covid going forward if they don't work.

Johnson says there is a "tripod we are resting our programme on the way ahead", starting with therapeutics and medicines, moving to the testing regime, and then the vaccines.

"That's the way forward, but if you talk to the scientists they believe things will start naturally to improve in the spring for other reasons", such as the improvement in weather conditions.

The PM adds: "I think the real progress we are going to see is with science.

"There isn't a virus that has threatened humanity that we haven't beaten."

Sir Simon says there are six "front runner" vaccines and the ones coming first are the "cleverest", so he remains positive.
