May associate vaccination with fewer FMDV carriers; leaves open causality and practice change pending prospective trials.
Does routine 6-monthly vaccination reduce the incidence of foot-and-mouth disease virus carrier cattle in an enzootic area?
Routine 6-monthly vaccination in an enzootic area significantly reduces the incidence of foot-and-mouth disease virus carrier cattle, suggesting eradication is possible through vaccination.
Anderson et al. (1974) studied this question.
