Vaccination rates amongst the plain community.

Reading the LNP today about our lack of a county level health department, measles outbreaks, and county wide vaccination rates it raised a question in my newly transplanted mind. Do we know vaccination rates in the plain community and are they counted in our vaccination rates for MMR declining below herd immunity? Could that be a leading factor in the county’s lots rates? I’d ask this of the county health department IF I HAD ONE.
