Why are vaccinations used in farm animals?

• A. They improve coat color
• B. They increase appetite
• C. Vaccinations prevent or reduce disease, protecting animal welfare and food safety
• D. They replace hygiene

Answer: (C)

Vaccinations train the immune system to recognize specific pathogens, so animals are protected from illness or suffer less if exposed. This lowers the spread and severity of disease on farms, which supports animal welfare by keeping animals healthier and reduces public health risks, protecting food safety since healthier animals are less likely to carry pathogens into meat, milk, or eggs. Vaccines work best when used alongside good hygiene and biosecurity measures; they do not replace hygiene. They also do not affect coat color or appetite, which is why those options aren’t relevant.
