That graph is from the UK, where most of the people spending time in hospital due to Covid are vaccinated. The thing is that as you can see from the graph, there's a huge difference in hospitalisation rates between age groups, and in the UK there's not that many unvaccinated people amongst the high-risk age groups. (Actually, I'd be interested what the error bars on that are because they're subtracting vaccinations from the population estimate to get the denominator of total unvaccinated people and it seems like that'd be very sensitive to errors in their population estimate.) So there is a signficant reduction in the risk of hospitalisation from vaccination right now, but we're seeing close to all the benefit that we're likely to at least from a society-wide perspective. There's no way to stop the hospital system from collapsing just by rounding up the remaining unvaccinated and getting them vaccinated. (Individual unvaccinated people might of course get a lot of personal benefit from getting jabbed, depending on age and health.)
