OP's point was more 'How would you measure unvaccinated people that lived because vaccinated people weren't filling the ER, so there were beds/staff to spare'?

That unvaxed outcome would need to go in the 'vaxed lives saved' column somehow, or else it looks like 'outcomes were the same either way' because the lives saved from vaccination spill over into the non-vaxed group because the vaccine prevented the healthcare system from melting down.
