Another data point in favour of vaccination.
This week, the number of cases of measles in LA County went up by one. He was a four-month-old boy whose parents were scrupulously following the vaccination schedule. However, MMR is a twelve-month vaccine, and he was too young for it. Now, he's fine--he's recovering, and I think today is even the day he and his dad (who was vaccinated but is unsure of his immunity, and the test wouldn't have gotten back until today anyway) get out of quarantine. But he very well might not have been. In the four days between when he became contagious and when he started to show symptoms, he might potentially have exposed a lot of other babies too young to vaccinate. Because that's how measles works; you aren't showing signs of it when you first become contagious. Get vaccinated if you haven't; his mother is begging people after having seen what her son went through.
