Researchers from Zoetis Inc. Publish New Studies and Findings in the Area of Circovirus [Comparison of predicted T cell epitopes in porcine circovirus type 2 isolates from 2017 to 2021 and selected vaccines (EpiCC analysis) confirms the global...].

A new report from researchers at Zoetis Inc. presents fresh data on circovirus, a globally important pathogen of swine. The study compares the T cell epitope content of four PCV2 vaccines to a larger sample of PCV2 field strains. The results show that a bivalent vaccine approach, combining PCV2a and PCV2b, provides greater T cell epitope coverage and potentially enhances vaccine efficacy. The study also highlights regional differences in PCV2 strains and emphasizes the global relevance of the bivalent approach. [Extracted from the article]
