Mycoplasma hyorhinis (Mhr) is a pathogen of pigs causing polyserositis and polyarthritis. The most susceptible population are nursery pigs of approximately 7 weeks of age, although we have shown that clinical signs can persist into finishing aged animals after a late-nursery infection. We have previously demonstrated the efficacy of a novel inactivated Mhr vaccine for the reduction of lameness and polyserositis in caesarian-derived colostrum-deprived (CDCD) pigs vaccinated at 3 weeks and challenged with Mhr at 6 weeks of age. Here we evaluated the duration of immunity (DOI) of the same vaccine. Vaccine or placebo was administered to CDCD pigs at 3 weeks of age. Pigs were challenged with Mhr at either 10 weeks of age (=7 week DOI) or 13 weeks of age (=10 week DOI). In the 7 week DOI, vaccination provided significant reductions in lameness (p = 0.0018), arthritis (p = 0.0002), and pericarditis (p = 0.0312) versus the placebo control. In the 10 week DOI, a significant reduction in arthritis (p = 0.0320) was observed in the vaccine group as compared to the placebo group. Both vaccine groups showed a significant increase (p
