Actually, that’s likely to be close to vaccinating all adults (over 16s for vaccine purposes) in England who actually want the vaccine.
There are 55m people in England. Under 16s will not be getting the vaccine, which takes off 11m ish.
Then there’s the assumption, in that report, that only 75% will want to take up the vaccine if offered. That takes off another 13m ish people.
Then we are left with 31m. And 25m being vaccinated. So pretty close!
Someone please correct me if I’m wrong!
