Vaccination and Herd Immunity in Farm Animal Welfare

Vaccination programs prevent disease suffering in farm animals and are a core component of preventive health welfare.

Key Facts

Foot-and-mouth disease outbreaks cause immense suffering before culling controls spread
Bovine viral diarrhoea virus causes significant losses and welfare harm in cattle herds
Vaccination against clostridial diseases prevents sudden death and disease suffering
Herd immunity through vaccination reduces disease pressure on unvaccinated individuals
Vaccination programs have significantly reduced the welfare burden of several major livestock diseases

Welfare Considerations

Vaccination is one of the most welfare-positive preventive health interventions in farm animal medicine. Preventing disease is welfare-superior to treating it — vaccinated animals do not suffer from preventable conditions. Herd immunity through high vaccination uptake protects individuals who cannot be vaccinated and reduces overall disease burden. The welfare case for vaccination programs is clear and complemented by the economic case — healthy animals are productive animals.
