Can Boris hit his vaccine target?

The government has failed to meet so many Covid-related targets so far that many will be extremely sceptical of the Prime Minister’s pledge on Monday evening to get the over-70s, front-line care workers and vulnerable people of all ages vaccinated by the middle of February. That is around 13 million first doses which will have to be delivered over the next six weeks – compared with just over a million which have been administered since the Pfizer vaccination programme began four weeks ago.
