A Novel, Multiple-Antigen Pneumococcal Vaccine Protects against Lethal Streptococcus pneumoniae Challenge.

abstract：:(DBA/N[female] X CBA/2[male])F1 males have been reported to be deficient in producing antibodies against a number of antigens, including carbohydrates (I. Scher, Adv. Immunol. 35:1-71, 1982). We show that F1 male mice, in contrast to females, made less lipopolysaccharide (LPS)-specific antibodies after immunization wi...
