Immunogenicity of a recombinant Saccharomyces cerevisiae - vectored multi-epitope vaccine targeting the infectious bronchitis virus S1 protein in broiler chickens
Background: The infectious bronchitis virus (IBV) remains a major constraint on poultry production because rapid viral evolution can reduce cross-protection between circulating variants and vaccine strains. A mucosal vaccine platform capable of coordinating antigen-specific humoral, cellular, and local responses may c...
