Zoetis - For vaccination of healthy swine 3 weeks of age or to prevent swine erysipelas disease caused by Erysipelothrix rhusiopathiae.


ER Bac Plus is used for vaccination of healthy swine 3 weeks of age or older and aids in preventing swine erysipelas disease caused by Erysipelothrix rhusiopathiae for a period of 20 weeks following the second dose in the vaccination regimen.


ER Bac Plus is a liquid, serum-free, clarified bacterin that has been chemically inactivated and combined with the adjuvant Amphigen® to enhance the immune response.

SAFETY AND EFFICACY: In laboratory and field safety studies of ER Bac Plus, no serious adverse reactions to vaccination were reported.

Efficacy of ER Bac Plus was demonstrated in 2 host animal studies conducted by Zoetis Inc.; an immunogenicity study and a duration-of-immunity study demonstrating efficacy 20 weeks after second vaccination.

Pigs vaccinated with ER Bac Plus, followed by challenge, had significantly fewer clinical signs of disease, including death, lesions, and fever, than nonvaccinated control pigs in both of the following studies.
