I agreed with you up to the point where you say that being against the vaccine is a personal decision.

I agree that especially research scientists quickly lose sight of humans and human interaction. I agree that it's impossible to know everything and that it's important to look outside of science and at humans.

But I don't agree that the refusal of a vaccine is something I should just accept.

I can accept it for tetanus - you're not infecting anyone else with it, so go ahead and refuse the vaccine. You're the only one who suffers. But when it comes to infectious disease? You're not just endangering yourself, but those who are not (yet) vaccinated. And the more people refuse the vaccine, the greater is the danger due to lack of herd immunity.

I think the vaccine needs to be properly tested for safety and effectivity. But beyond that? It's necessary to protect people, especially those who are unable to protect themselves.
