A novel nanoparticle vaccine, based on S1-CTD, elicits robust protective immune responses against porcine deltacoronavirus
{{output}}
Porcine deltacoronavirus (PDCoV), an emerging swine pathogen causing severe enteric disease in piglets, poses cross-species transmission risks, including humans. The C-terminal domain (CTD) of its spike protein harbors a key receptor-binding region with antige... ...
