Vaccination strategies for the control of circoviral diseases in pigs.
International Conference on Animal Circoviruses and Associated Diseases, European Society for Veterinary Virology, 2005
Vaccination appears to be the most efficient way of preventing porcine circovirus type 2 (PCV2)-induced diseases in pigs. MERIAL studied the efficacy of a vaccination scheme in sows and their piglets under laboratory conditions. An inactivated oil adjuvanted PCV2 vaccine (CIRCOVAC?) was administered intramuscularly to gilts at 5 and 2 weeks before breeding and 2 weeks before farrowing. It was shown that this vaccine was safe, highly immunogenic and induced a very good protection against PCV2 infection in piglets born to vaccinated sows. These results were confirmed in field conditions in very large numbers of animals. These trials showed that this vaccine reduced PMWS-mortality in pigs. The growth rate appeared to be more homogenous and the global mortality rates were reduced by about 50% in most of the farms involved.
