manufacturers and regulators, with a perception that horse and human
welfare were not priorities for these groups (Manyweathers et al.,
2020). Some owners requested HeVD antibody titre testing as an
alternative to HeVD vaccination due to concern about HeVD vaccine
reactions and perceived over-vaccination (Barrett, Wiethoelter, &
Halpin, 2021). In contrast, following a deliberative process, community
juries who were comprised of the general public (not necessarily horse
owners) were confident that vaccination mitigated HeVD risk safely and
effectively, with some jurors agreeing that the promotion of HeVD
vaccination could be implemented immediately and affordably to increase
vaccination uptake (Degeling et al., 2018).
