Households in Tanzania face foot-and-mouth disease (FMD) challenges as 50% own livestock, grazing is open, and 4 of 7 FMD serotypes are present. Vaccination could help but vaccines are not matched to serotypes. The study surveyed 432 households to determine what drives FMD vaccination decisions and how proximity of risk influences those decisions. Results showed higher income levels and experiencing an outbreak near a neighbor increased willingness to pay for emergency vaccination, while using government veterinary services decreased it. Improving vaccine effectiveness and matching serotypes could increase routine vaccination uptake.
