Immunogenicity and protective efficacy of a fucoidan adjuvanted bivalent inactivated vaccine against Aeromonas hydrophila and Edwardsiella tarda infections in Nile tilapia

Puntos clave

• Immunogenicity increases with fucoidan adjuvant for bivalent vaccine against infections.
• Protection against both Aeromonas hydrophila and Edwardsiella tarda enhances with vaccination.
• Assessment using bivalent inactivated vaccine shows robust immune response in tilapia.
• Findings may support improved vaccination strategies for tilapia aquaculture, indicating need for further studies.
