If the vaccine really works, it should be enough that those who want it and think it is useful, get it. No intelligent reason to force it for people who don't want it.
That is not actually the case. In order for a vaccination to be truly affective, enough people have to receive it in order to get herd immunity. Thus, it requires the cooperation of the whole community, not just some individuals. Also, vaccinations are only effective for the majority of people, not for every person. Someone can be vaccinated, and still made sick by someone who refused vaccination.
My daughter was originally vaccinated for whooping cough (pertussis) when she was a baby. It's pretty standard. However, in all cases, vaccines are never 100% effective. There are always a small minority of people who are vaccinated for whom the vaccine does not give them immunity. My daughter was one of those people. Later in her life, she had friends who were anti-vaxxers. They came down with whooping cough because they were unvaccinated, and then gave this disease to my daughter who did not have immunity. It was just awful. It ended up permanently damaging her lungs. She now is prone to pneumonia as a result, threatening her life. This is directly the fault of her friends who refused vaccination.
So long story short, it is not a personal private decision. What you do impacts the health of all those around you.
