Features & Benefits

Whole-Herd Protection

J-VAC® vaccine is the only vaccine of its kind approved for usage in the whole herd. In just two doses, J-VAC vaccine protects against coliform mastitis caused by E. coli and endotoxemia caused by E. coli and Salmonella Typhimurium. The unique TANDEM™ adjuvant in J-VAC vaccine keeps antigens in suspension, releases them over time, and stimulates enhanced immunity.


Flexible Administration

  • J-VAC vaccine is easy to administer with a whole herd, two-dose protocol, and can reduce the incidence of clinical coliform mastitis cases by 81%.* 
  • Labeled for flexible administration, with intramuscular and subcutaneous injection-route options.
