His claim is wrong ........ look at the WHO data on one of the previous links I posted. I presume that all countries feed their own data into the WHO, so that would presumably be the best source for comparisons.
They also show the data table ....... so I downloaded it, hid a few columns etc, and came up with this easy comparison just for major EU countries.
Germany have more vaccinations than us (understandable given their population).
As I say, we're doing well, but not the leader in anything.
(Definitions are also on the link)
