Useful to review the stats on this, particularly in view of the way it chimes in with the reduced Ambulance times story above
So far, more than 52 million people have had a first vaccine dose - some 92% of over-12s. More than 49 million - 85% of over-12s - have had both doses.
While uptake of first and second doses dropped off late last year, there was a steep rise in people having boosters. However, booster numbers dipped over the Christmas holiday period and remain low.
More than 38 million booster doses have been administered across the UK so far.
