Global dynamics of vaccine effectiveness and genotype shift in porcine circovirus 2: A cross-temporal analysis.

Open veterinary journal - 1 Sept 2025

Orosco Fredmoore L

Abstract excerpt

Background: Porcine circovirus type 2 (PCV2) has caused annual economic losses exceeding US$2 billion to the global swine industry, with mortality rates of 5%-20% in unvaccinated herds. Following the 2006 introduction of PCV2a-based vaccines in 2006, genotype dominance shifted sequentially from PCV2a to PCV2b and from 2010 onward to PCV2d. However, a unified, long-term evaluation of how vaccine uptake influences...
