So they know for sure it was caused by people refusing vaccines and not uncontrolled immigration?

[cripplecreek]

That would be my guess.

Those who vaccinate provide a kind of wall to protect the unvaccinated…until enough go unvaccinated.

Herd immunity would protect people, if everyone eligible to be vaccinated were vaccinated. With the minimum of about 90% of the population vaccinated, an occasional infected immigrant would not be able to cause an epidemic. What we are seeing in New York is measles spreading between unvaccinated Americans.

Maybe we should take Jenny McCarthy and the other anti-vax loonies and send them to some hell hole in Africa, so they can see first-hand what disease does to unvaccinated children. There is no reason to bring them back afterwards.
