The vaccination drive is lagging far behind in many Amish communities. In Ohio's Holmes County, home to the nation's largest concentration of Amish, just 14% of the county's overall population is fully vaccinated. While their religious beliefs don't forbid them to get vaccines, the Amish are generally less likely to be vaccinated for preventable diseases such as measles and whooping cough. Though vaccine acceptance varies by church district, the Amish often rely on family tradition and advice from church leaders, and a core part of their Christian faith is accepting God's will in times of illness or death. Many think they don't need the COVID-19 vaccine now because they've already gotten sick and believe their communities have reached herd immunity, according to health care providers in Ohio, Pennsylvania and Indiana, home to nearly two-thirds of the estimated 345,000 Amish in the U.S.. "That's the No. 1 reason we hear," said Alice Yoder, executive director of community health at Penn Medicine Lancaster General Health, a network of hospitals and clinics. Experts say the low vaccination rates are a reflection of both the nature of the Amish and the general vaccine hesitancy found in many rural parts of the country. Some health clinics that serve the Amish are hesitant to push the issue for fear of driving them away from getting blood pressure checks and routine exams.
