From the Wall Street Journal (paywall):

Legions spurned a long-proven vaccine, putting a generation at risk

A measles outbreak infected 1,219 people in southwest Wales between November 2012 and early July, compared with 105 cases in all of Wales in 2011. One of the infected was Ms. Jenkins, whose grandmother, her guardian, hadn't vaccinated her as a young child. "I was afraid of the autism," says the grandmother, Margaret Mugford, 63 years old. "It was in all the papers and on TV."

(I wonder if 'Indigo' and 'Crystal' kids are naturally immune to measles.)
