Nah, that's a poor argument. The medical industry would make more money if they let the people get sick so they need to be hospitalized for weeks or even, in the case of some polio victims, need to be in an iron lung for the rest of their lives.

(In Ontario, for example, a cost-benefit analysis shows that a universal free influenza inoculation program reduces costs of the medical system; see http://www.plosmedicine.org/article/info%3Adoi%2F10.1371%2Fj... .)

I can turn the argument around: companies don't want people to get vaccinated so they can sell more expensive palliative care. Why would a hospital want to get less business if more people are vaccinated and so don't need their services?

If a given argument predicts X and it predicts not-X, then it's a poor argument. This appeal to the profit motive is a poor argument.
