When an article in a British medical journal made a link between the MMR vaccine and the rise in autism, it eventually built into a criticism of vaccinations from parents.

And with ignorant spokespeople not bothering to investigate the science of immunization, there maybe a much greater threat: the spread of the diseases the vaccines were designed to stop in the first place.
