You don't have a right to not catch diseases from infected people.
In my state, knowingly spreading disease (e.g. by going to the crowds) if you know that you're infected is against the law.
People do have a right to not submit themselves to injections they don't agree with.
No-one has an absolute right to anything. All rights are ultimately balanced against the good of society. That's why free speech does not preclude libel & slander laws, for example, and why RKBA doesn't mean that you have a right to own a cruise missile.
In this particular case, your right to control your body is overridden by the extreme degree of common good that results from mandatory vaccinations, combined with a very low degree of personal invasion that such a vaccination actually entails.
