As a historic measles outbreak continues to impact Pennsylvania Amish country, health officials report that members of the state’s Plain communities are showing a newfound openness to immunizations. The surge, centered primarily in Lancaster County, forms the core of the nation’s worst measles resurgence in decades, driven by a combination of falling vaccination rates and high transmissibility.
State figures indicate that Pennsylvania has recorded more than 1,350 measles cases this year, with more than a third in Lancaster County alone. State health department updates show active hospitalizations and ongoing transmission across the region, while community leaders emphasize that the true count is likely higher because many infected individuals never seek medical care.
Interconnected Communities and Public Health Outreach
Although the Amish and conservative Mennonites often avoid civic participation for religious reasons, healthcare providers stress that these groups are deeply integrated with the wider public through commerce, schools, and shared public spaces.
Historical Context and Evolving Vaccine Attitudes
Vaccination rates, and attitudes about vaccines, range widely among the Plain communities.

State Data and Broader Vaccination Declines
Public health experts emphasize that declining herd immunity is a statewide and national concern rather than an issue isolated to religious communities. According to the Centers for Disease Control and Prevention, national kindergarten MMR coverage fell to 92.4% for the 2025–26 school year, down from 95.2% in 2019–20.
In Pennsylvania, kindergarten vaccination rates dropped to 93.2% last year, with Lancaster County recording an 88% rate and higher rates of religious or philosophical exemptions. As winter approaches and indoor gatherings increase, medical professionals continue monitoring transmission trends while urging communities to prioritize vaccination to protect vulnerable populations.
