abstract：:The immunogenicity of capsomeres of human papillomavirus type 33 was evaluated in a dose-response analysis. Capsomeres were obtained free of capsids by expression of L1 carrying the single point mutation C427S. Neutralizing antibodies were detected using an in vitro pseudoinfection assay. Capsomeres induced type-speci...
