Safe, Comprehensive Coverage
Veterinarians choose Vira Shield® for convenient, one-bottle vaccination against reproductive and respiratory viruses for many reasons:
- 12-month duration of immunity (DOI) label claim for Lepto hardjo-bovis (LHB), the most common cause of leptospirosis in the U.S.1
- Up to 13 disease-fighting antigens in one ready-to-use bottle
- Safe for use on all cattle, even pregnant cows and heifers
- The only vaccine to feature 3-way BVD coverage including cytopathic (CP) Type 1, noncytopathic (NCP) Type 1 and Type 2
- Demonstrated to deliver enhanced IBR fetal protection eight months postvaccination2
- Provides both humoral and cell-mediated immunity
- Powerful, long-lasting control with state-of-the-art adjuvant, Xtend® SP

Protect Against the Most Threatening Diseases
Vira Shield offers proven protection against common diseases that can threaten your herd and your profitability.
BVD Protection Unlike Any Other
|Most Common BVD Coverage|
As the only vaccine to feature three-way BVD coverage, Vira Shield HB eliminates the hassle of using multiple products for complete respiratory and reproductive control. Research shows that 98 to 99 percent of field samples diagnosed are NCP BVD1
Protect Against IBR Abortion
Veterinary diagnostic labs are reporting a significant increase in the number of IBR abortions in pregnant heifers and cows. In a fetal protection study, animals vaccinated with Vira Shield 6 and nonvaccinated animals in the control group were challenged with virulent IBR at approximately six months of gestation and almost eight months postvaccination2.
Providing a Cell-Mediated Immune (CMI) Response
To deliver the most effective immune response against viral diseases like BVD, IBR and BRSV a vaccine needs to produce two distinct types of immunity—humoral and cell-mediated.
- Research shows Vira Shield stimulates a highly effective CMI response to BVD through the production of antigen-specific interferon gamma3.
- Additional research found that an adjuvanted, inactivated vaccine provided a much stronger CMI response to BRSV than MLVs4.
