This has been all over the local Portland news for weeks. Here are a few more details (but from memory so I could be slightly off): About 50 kids in Clark County have come down with measles so far. 49 of kids with measles were unvaccinated. 1 kid with measles received one dose of the vaccine. SOP is for two doses. No kid that received both doses has contracted measles. I haven't seen any reports of adults contracting measles. One vaccine dose is about 93% effective, 2 doses are about 97% effective. In Washington State (not sure if state as a whole or just Clark County) about 22% of kids aren't vaccinated. In Oregon about 11% of kids aren't vaccinated. --- When I was a kid smallpox vaccine was very common and polio vaccine was coming into use. People took vaccination very seriously. Read some history of those two diseases and you will quickly understand why. In various settings (e.g. family doctor, various school nurses, etc) I probably received 2 doses of injected polio vaccine and 5 doses of oral vaccine. At least that I can remember. The number was probably higher. That's how serious the effort was to prevent polio. One high school teacher (polio victim) needed some metal contraption around his leg to help him walk. I.e. there were visible reminders of how serious polio was. Smallpox vaccine was easier to keep track of. It left a slight scar on many peoples upper arm. So if you had the scar, it meant you had the vaccine!
