Proactive vaccination programmes for cattle are one of the most effective and welfare-positive interventions available to farmers, preventing diseases that cause significant suffering across both beef and dairy herds.
Disease prevention through vaccination is among the most impactful welfare interventions available in cattle farming because the diseases prevented cause severe suffering. BVD infection can cause fatal mucosal disease — a haemorrhagic, painful condition with no effective treatment. Clostridial diseases kill rapidly after a period of acute distress. Respiratory viruses cause painful fever, laboured breathing, and the secondary bacterial pneumonia that causes permanent lung damage. Vaccination prevents these acute welfare emergencies. The act of vaccination itself causes brief, minor discomfort — this is trivially outweighed by the welfare benefit of preventing serious disease. Farms with comprehensive, timely vaccination programmes have measurably lower disease burdens, shorter treatment courses when disease does occur, and lower mortality rates.
