The solution is to vaccinate your children and work for high rates of Herd Immunity.
With low rates of Herd Immunity, the probability of even those who are vacciinated contracting measles increases.
As far as vaccination rates for measles is concerned, vaccination rates in Mexico are almost the same as they are in th US.
We can only blame ourselves for the measles outbreak.
