No, it was the rates per 100,000 people in each cohort, and the vaccinated were getting more infections per 100,000. It is a rate, not an overall number, and the rates of infection were higher in the vaccinated across almost all age bands. But then the UKHSA stopped publishing the data. Why would they stop doing this?
Most of the vulnerable were vaccinated in December 2020 and very early 2021 and Covid deaths spiked later in February of 2021, before rapidly falling off again, just like any other mostly seasonal virus, and just like the initial wave in 2020 fell away all by itself (without anyone being vaccinated). So very little to do with the vaccines. It did the same in countries that did not lock down as well, rising and falling naturally. Gompertz curve is the technical name for this.
