When measles struck, investigators wanted answers. Instead, some parents lied

Across California, health investigators say that anti-vaccine parents are increasingly refusing to cooperate with them as they try to stem outbreaks of diseases such as measles.

As a measles outbreak spread in Northern California last spring, public health workers called the family of a young boy who they feared had been exposed to the disease.

The boy’s mother, however, said her 7-year-old already had his shots, so they need not worry.
