In 1983, Ron Sprouse, M.D., Ph.D., and Harold Garner, DVM, both working at the University of Missouri-Columbia, researched and developed a vaccine for horses that proved effective against a broad spectrum of bacteria. Along with Dr. Sprouse’s wife, Dorothy, and Dr. Garner’s wife, Patsy, they founded the company, formerly known as IMMVAC, to commercialize the novel technology.
ENDOVAC manufactures vaccines for livestock to aid in the protection of numerous diseases caused by gram-negative bacteria. The first product, Endoserum for Equine, received its USDA license in 1986.
