A vaccine comprising a) an emulsion comprising an oil and one or more emulsifiers, b) a heat treated bacterin comprising a suspension of killed bacteria, wherein the killed bacteria are Leptospira species and wherein the heat treated bacterin has a lipase activity of 50% or less than the lipase activity of the bacterin before the heat treatment, and c) one to nine porcine disease causing viruses selected from the group consisting of Porcine herpes viruses, Pseudorabies virus, Classical swine fever virus, Porcine epidemic diarrhea virus, Porcine hemaglutinating encephalomyelitis virus, Porcine parvovirus, Swine Influenza, Transmissible gastroenteritis virus, and Vesicular stomatitis virus.
2. A vaccine according to claim 1 further comprising a lecithin preparation, and an alum based adjuvant.
3. A vaccine according to claim 2 further comprising a lecithin in oil preparation.
4. A vaccine according to claim 1 further comprising a heat treated bacterin comprising a suspension of killed Erysipelothrix rhusiopathiae.

11. The vaccine of claim 1 wherein the emulsion is stable.
12. The vaccine of claim 8 , wherein the emulsion is stable.
13. A vaccine comprising a) an emulsion comprising an oil and one or more emulsifiers, b) a heat treated bacterin comprising a suspension of killed bacteria, wherein the killed bacteria are Leptospira species and wherein the heat treated bacterin has a lipase activity of 50% or less than the lipase activity of the bacterin before the heat treatment, and c) one to four porcine disease causing viruses selected from the group consisting of Porcine Adenovirus, Porcine Circovirus, Porcine Respiratory Corona virus, Porcine Reproductive and Respiratory Virus.
14. A vaccine comprising a) an emulsion comprising an oil and one or more emulsifiers, b) a heated treated bacterin comprising a suspension of killed Erysipelothrix rhusiopathiae and wherein the heat treated bacterin has a lipase activity of 50% or less than the lipase activity of the bacterin before the heat treatment, and one to four porcine disease causing viruses selected from the group consisting of Porcine Adenovirus, Porcine Circovirus, Porcine Respiratory Corona virus, Porcine Reproductive and Respiratory Virus.
