Sounds good in theory. In practice, there have been disease outbreaks in communities with 100% vaccination rates against that disease. Most vaccines don't even cover all the known strains, forget the new mutations.
IMO, vaccination is no replacement for promoting a strong natural immunity and preventative medicine. Both of which are virtually thrown out the window in modern medicine.
I'm for any medicine that can be proven to work through the techniques espoused by modern medical science. If you can prove it works in a placebo-controlled double-(or dare-i-dream-triple?)-blind study, then I'm all for it.
Anything less means "controlled study needed."

And the more a vaccinated person is exposed to a disease, the more permutations of that disease get thrown at the vaccinated population. If one takes, then we have the whole problem of the disease all over again. One consequence of the short life of bacteria and the mutation of viruses is that they're basically brute-forcing our immunities of every population they're in contact with.
This is why it's _so important_ that people follow vaccination programs. Eventually we'll have to deal with new diseases, but if we aggressively and correctly vaccinate, we can stave off that day for a lot longer than if we half-ass it.
