Who We Are
ENDOVAC Animal Health is located in Columbia, Missouri, and has been in business since 1983. Founded and owned by the Sprouse family, ENDOVAC Animal Health is a proactive animal health company that is focused on premium science. We maintain a culture that is dedicated to customer-centric integrity and an animals first mentality. Our strong foundation led us to the opening of a new production and manufacturing facility in the summer of 2020.
What We Do
ENDOVAC Animal Health manufactures vaccines for livestock and companion animals to aid in the protection of numerous diseases caused by gram-negative bacteria. Today, our main focus is beef and dairy cattle with developing product lines for equine and swine. Our dynamic team is here to assist veterinarians and producers with any questions about our product portfolio.
IMMVAC was founded to commercialize a novel technology developed by Dr. Ronald F. Sprouse, Professor of Pathology, and Dr. Harold E. Garner, DVM, at the University of Missouri.
The first product from IMMVAC, Endoserum® for equine, was licensed by the USDA.
The flagship product line, ENDOVAC® vaccine, was licensed and began manufacturing.
Dr. Ronald and Dorothy Sprouse purchased all shares of IMMVAC from the Garners.
Facilities expanded to meet production demands and additional office space.
Son of Dr. Ronald and Dorothy Sprouse, Kevin Sprouse, took over as Executive Vice President.
ENDOVAC-Bovi® was rebranded to ENDOVAC-Beef® and ENDOVAC-Dairy®.
IMMVAC, Inc. changed its name to ENDOVAC Animal Health.
ENDOVAC Animal Health saw the need for improvement and continued growth. The most modern vaccine production facility in the United States was completed near the original facilities in Columbia, MO. Construction was started to transition the original production facility into research and development.
Today, ENDOVAC Animal Health is owned by Kevin Sprouse in Columbia, MO, with Steve Knorr serving as Company President. The product portfolio is managed by a team of industry-leading production and animal health experts. Circulation of the vaccine lines is completed through our distribution partners. ENDOVAC Animal Health is looking to the future to maintain status as a stand-alone animal health company.
