Every year there are measle outbreaks here.
A couple of years ago 8 people died during an outbreak. 2 others were left blind. They have also had outbreaks of pertussis and diptheria. So we have a large pool of unvaccinated people in the immediate area that can contract the deseases and pass it on to other unvaccinated children. The local schools consider it a big enough health issue to refuse to allow unvaccinated children to attend school during outbreaks because the risk is so high.
