In a completely controlled environment, sure it would be that easy. Unfortunately, we don't live in such an environment.

There are other variables to account for, such as lifestyle differences between people who do or don't get vaccinated. What proves that the same people that would opt to get vaccinated don't have better hygiene habits, contributing to a lower mortality rate?

National Healthcare systems often don't cover highly specialized treatment and research medicine. It's not even that they won't pay for it; they often just straight up don't offer it.
