Are you referring to the same ONS data mentioned in [1]? That figure is highly misleading.
Was this one? Mine is similar but released by PHE weekly, with more breakdowns

But even looking at this one you can see the trend shifting from end of September, where vaccinated are now dying more than unvaccinated
Do you think is misleading? Why? It is being used for months
