The problem with this thinking on something like vaccines is that vaccines literally rely on a certain percentage of the population having received the vaccine. It's not actually possible to allow a personal choice policy if you want a vaccine to be effective.

I wouldn't necessarily declare that vaccines rely on sufficient population vaccination, but there's always going to be people who cannot take the vaccine (e.g. immune-compromised individuals) and their protection comes from the population having a high percentage of immunity due to the vaccines. Of course, having the majority being immune means that any outbreak tends to finish quickly as the virus runs out of people/vectors to infect.
