EBA Vaccine Trials Advance At SFREC

Epizootic bovine abortion (EBA), also referred to as foothill abortion, is one of the most serious cattle diseases in the Western United States. UC researchers, Professor Jeff Stott and Specialist Myra Blanchard from the UC Davis School of Veterinary Medicine have made major headway in developing a vaccine for this disease and currently are mid-way through a multi-year field trial examining vaccine field efficacy. This disease is carried by ticks and is present in many foothill regions making SFREC a natural outdoor lab to evaluate field efficacy.

Last Wednesday researchers checked pregnancy status and condition on heifers assigned to the study. By August, heifers will be moved to irrigated pasture where SFERC staff can monitor animals closely for how the vaccine improves calving success and calf health.
