Inoculated into breeding hens, it stimulates high-titre protective IgG antibodies transferred via egg yolk to broiler chicks, providing maternal passive immunity against E. maxima, E. tenella, and E. acervulina.
- Contrasting Vaccines: Paracox, Nobilis COX ATM, and ADVENT are live or live-attenuated coccidiosis vaccines containing live sporulated oocysts.
