How can a vaccination be mandated?

Answer 1

You would have to pass a legal bill requiring all Americans to receive the treatment, however even if one could get such a bill passed the idea is absolutely ridiculous because the costs involved to get the vaccine, as well as pay professionals to administer it would be ridiculous. Even if one had such finances, you couldn't guarantee that everyone would receive the vaccine because a lot of people are against them.

In the US, in New York, they did enact a law that certain workers in health care, who had close contact with patients, must be vaccinated against H1N1/09 to continue to do that work. The rationale was that the public legislators made the rights of patients take priority over the rights of licensed workers. It was felt that patients, some of whom may not be conscious, were at high risk to contract and have complications from the co-morbidity of their underlying reason for hospitalization and H1N1/09. In some cases the workers who did not want to be vaccinated could either be reassigned to jobs that were not in direct contact with patients (if the employer allowed), or find other employment. There were some situations where the employer had to reassign those with medical reasons (like allergic reactions) why they could not take the vaccination.
