Protivity™ is a modified-live bacterial vaccine that is effective in protecting healthy beef and dairy calves against respiratory disease caused by Mycoplasma bovis (M. bovis). Calves 1 week of age or older can receive Protivity.
This product has been shown to be effective for the vaccination of healthy cattle 1 week of age or older against respiratory disease caused by Mycoplasma bovis. Duration of immunity has not been established.
A field safety study was conducted to demonstrate the safety of Protivity™ in dairy and beef calves of varying sources, including those raised in high population densities, high-stress situations and intensive calf-raising facilities. Only antimicrobials that had no activity against M. bovis were allowed. In this study, a total of 1,069 calves (355 unvaccinated controls and 714 vaccinated with Protivity) were enrolled at three distinct geographical locations. The age range of the calves enrolled were between 8 days of age and younger and approximately 30 days of age. The calves were administered Protivity (n = 714) by subcutaneous route on Day 0 and Day 21 of the experiment design. The frequency of adverse events (mainly neonatal diarrhea and respiratory infections, which are common in this age of calves) in the control and vaccinated groups were similar. One out of 714 (0.14%) vaccinated calves developed arthritis where the vaccine strain was isolated from the affected joint.3
Protivity™, as the first modified live vaccine for M. bovis, demonstrates effective protection against respiratory disease. Despite different tools available to manage disease challenges, respiratory disease caused by M. bovis continues to be a problem.1
This modified-live M. bovis strain may disseminate into joint synovial fluid and may cause arthritis.
