Vaccination Can Help Control PCV2
Studies and field experience now show vaccination can play a key role in helping to control PCV2 and PCVAD.
Suvaxyn® PVC2 One Dose
is the first fully licensed PCV2 vaccine that can help producers and veterinarians stop circovirus in its tracks.
Factors that play a role in PCVAD1,2
Several "building blocks" contribute to PCVAD development. The disease is best managed by controlling as many blocks as possible, which includes reducing and even preventing PCV2 viremia.

Key building blocks to control:
- Porcine circovirus type 2 (can now be controlled with vaccination)
- Differences in virulence between PCV2 isolates (can now be controlled with some vaccines)
- Infectious co-factors (control with vaccines, treatment and management)
- Trigger factors that induce immune stimulation (control with management changes and mycoplasma vaccine timing or selection changes)
- Good production practices to minimize host susceptibility (management changes to reduce pig stress, improve hygiene and reduce overall disease challenge)
