Schering-Plough Animal Health introduces MaxiVac-M+, a combination vaccine for the prevention of pneumonia caused by swine influenza virus and Mycoplasmal pneumonia. In addition, MaxiVac-M+ and M+Pac can now be used up to 21 days before slaughter. The expanded label claim from USDA gives veterinarians and producers added flexibility as to when to vaccinate growing pigs for Mycoplasmal pneumonia. Both vaccines contain Emunade, an oil-in-water adjuvant that provides rapid and prolonged immune response.
