Porcine circovirus type 2 (PCV2) vaccination of conventional pigs prevents viremia against PCV2 isolates of different genotypes and geographic origins.
Vaccine (2008) 26, 1063—1071
The efficacy of recently developed porcine circovirus type 2 (PCV2) vaccines has not been tested yet against PCV2 isolates of the two proposed genotypes. In the present work, the efficacy of a subunit vaccine containing PCV2 capsid protein was evaluated by using a challenge model with four different PCV2 isolates of different genotype and geographic origin. The vaccine prevented the development of viremia in all cases as well as significantly decreased nasal and faecal shedding of the virus. Also, the vaccine elicited PCV2-specific neutralizing antibodies to PCV2 even in the presence of maternally derived immunity. © 2007 Elsevier Ltd. All rights reserved.

New PCV2 vaccine aiming at one-shot approach.

Using a new two-shot vaccination has proven to be efficacious in improving the performance of pig herds in Germany. The first preliminary trials of using the same vaccine in a one-shot regime suggest similar or even better results.
