The US veterinary vaccines market is projected to reach USD 6.50 billion by 2031, growing from USD 4.67 billion in 2026, at a CAGR of 6.8% during the forecast period.
Growth in the US veterinary vaccines market is stimulated by expansion in the companion animal population, rising pet ownership, increasing incidence of zoonotic diseases, and initiatives by government bodies to promote animal health. This, in turn, enhances the demand for preventive vaccination in companion animals and livestock. However, high costs associated with vaccine development, storage, and administration act as a hindrance to market growth to some extent. Effectively balancing these drivers and constraints will remain paramount for the sustainable development, availability, and adoption of veterinary vaccine solutions in the United States.
Some of the prominent players operating in the US veterinary vaccines market include Zoetis (US), Merck & Co., Inc. (US), Boehringer Ingelheim International GmbH (Germany), Elanco (US), Virbac (France), Ceva (France), Phibro Animal Health Corporation (US), Hester Biosciences Limited (India), Neogen Corporation (US), HIPRA (Spain), and Vaxxinova International B.V.
