One of the first things they do in an outbreak is try to trace the disease back, to find the point of origin, Patient Zero. In almost every outbreak they can trace it back to an unvaccinated person. In an outbreak in San Diego they traced it back to a kid who was unvaccinated and exposed during a trip to Europe. Vaccines aren't a 100% guarantee against disease, but, at the least they can mitigate the disease if you do manage to catch it.
