Zoetis Spirovac Leptospira Hardjo Bacterin Cattle Vaccine, 20mL/10 Dose

SPIROVAC is for vaccination of healthy cattle four weeks of age or older, including those pregnant and/or lactating, for the prevention of infection by Leptospira borgpetersenii serovar hardjo-bovis, including reproductive and renal tract colonization, and urinary shedding for up to 12 months. Vaccination with SPIROVAC also aids in the prevention of fetal infection.

Cattle are the primary reservoir for L. borgpetersenii serovar hardjo, resulting in maintenance infections that are often chronic and subclinical in nature but can cause economic loss to cow/calf and dairy operations.¹ SPIROVAC contains chemically inactivated whole cultures of L. borgpetersenii serovar hardjo-bovis.
