Starting off, Alex Eggen, head technical services at the animal health company's global swine business unit, painted a worldwide picture of PCVD and put this in a historical perspective.

  • 4. Dr Artur Summerfield, of the Institute of Virology and Immunoprophylaxis, Switzerland, explained how PCV2 can become so dangerous: it interacts with dendritic cells, which play a vital role in the initiation of immune responses in pigs.

  • 5. In essence, Summerfield indicated, PCV2 is not a very complicated virus, as it has a very small genome, with only three proteins; it is badly equipped with genes - and it is slow. Compare that to Foot-and-Mouth Disease (FMD) or African Swine Fever (ASF).

  • 9. Fort introduced the concept of a 'window of vaccination' for piglets (the zone in green). Vaccinating too early would not be necessary as the animals are still protected by maternally derived antibodies (MDA's) from sows. Vaccinating too late might constitute a risk as the period between 7-12 weeks is critical with high numbers of PCV2 viraemia.

  • 11. Dr Peter Irgang, of the veterinary practice Die Tierarzte, Austria, presented results from Austrian farms. He demonstrated the effect of subclinical PCV2 infections by presenting farm results obtained with a farm strategy before the availability of a PCV2 vaccine. Feed quality improvements, disinfection, several other vaccinations, use of antibiotics and increased biosecurity still could not prevent many pathogens being present in the pigs.

  • 14. An image showing the background of the PCV2 vaccine. In general, it is built of 'the right quantity of antigen', combined with a potent adjuvant of Diluvac Forte and Microsol. According to the animal health company, the new vaccine's characteristics are protection until at least 25 weeks of age and the fact that it can break through MDA's. One-shot vaccination at three weeks is recommended.
