Is that less lethal than Influenza in people who’ve also been vaccinated against Flu? If that makes sense… or is it just across society as a whole?
And if so (the latter), what percentage of the population are Influenza vaccinated vs what percentage are Coronavirus vaccinated?
Sorry for all the questions.
They're population level stats. If you go to the linked article they go deeper into how the pattern looks in different age groups. Broadly, some combination of infection and vaccination has moved us from a position where the IFR was worse than flu in every age group (and much worse for anyone over 40) to a position where the IFR is lower than for flu, even amongst the oldest.
The flu IFR is based on data from a study in New Zealand, where flu booster jab takeup is typically around 70% in the 65+ group. Keep in mind though, that's annual booster takeup - the number that have had a flu jab sometime will be higher, and almost all of them will have had flu multiple times as well. Covid vaccine takeup in the UK in the 65+ group is more than 95% and close to 100% in the over 70s.
What that means, looking at the UK whole population:

"For every 100,000 Omicron infections, 35 will result in death, while the equivalent number of flu infections will lead to 40 fatalities, the data showed. Even among the over-80s, where about one-in-200 Omicron infections still results in death, this figure is now lower than the equivalent for flu."
They are using "infections" in their analysis (rather than cases), and they base their infection numbers on the weekly ONS random survey, which means they pick up asymptomatic and unnoticed infections, as well as the recorded kind.
Keep in mind, we're talking about rates - if you've got lots of infections, you still get lots of deaths. That's where we're at now. Covid infection rates are currently much higher than the flu infections we see in a typical flu season and overall respiratory disease deaths are higher as well - despite the fact that we aren't really "back to normal" in terms of mixing and behaviour etc. As it happens, flu cases are low at the moment, presumably because we aren't actually back to normal.
