No, as I said and if you look at the table, the rates are per 100,000 vaccinated and 100,000 unvaccinated so completely comparable.
Oh god, I take a couple of hours off to watch a movie, I come back and find people trying to use the UKHSA/PHE case data for comparative purposes.
First, the issue of how problematic the NIMS denominator is has been incredibly well-trodden, especially for sub-70yo age groups. It significantly over counts the population, and therefore overcounts the unvaccinated population (we have exact numbers for vaccinated obviously.) UKHSA has dug its heels in on using this despite being told off by the stats
Second, they literally say in the reports that this data should not be used for comparative purposes for a range of others issues that have nothing to do with the denominator, including evidence from ONS that one factor in choices not to vaccinate can be recent recovery from Covid (so there may be a disproportionate level of immunity already in that population.)
But the denominator is the main issue here. Here’s some more information - great summary in the FT.
James Ward, Oliver Johnson, John Burns Murdoch et al give good explanations on Twitter if the words of David Norgrove, head of the UK Statistics Authority isn’t enough. (He said ‘Those numbers were misleading and wrong and we’ve made it very clear to UKHSA.’)
So no. They’re not completely comparable. Or comparable at all. Sorry, @Lakes74, but hopefully that’s clarified now and if not do go and look at some of the clever Twitter folk I mentioned, they also have modelling with ONS data (which over represents elderly groups but is much closer on all other age groups and is probably a better overall denominator.)
Next!
