Lancaster County has recorded 268 measles cases and two deaths, the highest case count in Pennsylvania, with the outbreak centered in the Plain community.
100% of diagnosed patients in the county were unvaccinated, prompting the Pennsylvania Department of Health to recommend an additional measles shot for children starting at 6 months, ahead of the standard 12-month dose.
Plain community residents said information has spread largely by word of mouth, and some families with measles stayed home to avoid infecting others.
Community views remain mixed: one vaccinated mother said MMR is a personal choice rather than a religious one, while another resident said he was unconcerned because he had measles as a child.
