How many people have had their booster jab?published at 12:12 Greenwich Mean Time 14 December 2021
There are a lot of people awaiting a booster now because the eligibility criteria has dropped from six to three months after a second dose.
Before that, the programme had reached 80% of those eligible, but that has now dropped to 51%, figures show.
If the aim is to give a booster to all those eligible by the end of December, then it would taken more than 61,000 jabs a day – more than three times the current daily average.
If the aim is to give everyone a booster by the end of January, then that could be done with an average of 23,000 boosters a day.
The number eligible only rises by a total of 20,200 over January.
In March, 38,000-40,000 vaccines were given out a day at the peak.
