Induction of cross-serovar protection against genital chlamydial infection by a targeted multisubunit vaccination approach.

ABSTRACT: An important consideration for antichlamydial vaccine development is the induction of cross-serovar protection, since multiple serovars (D to L) of Chlamydia trachomatis cause genital infections. We have shown previously that vaccination with C. trachomatis-derived recombinant chlamydial protease-like activity factor (rCPAF) induced significant earlier resolution of Chlamydia muridarum infection and reduced oviduct pathology. However, the vaccinated mice continued to shed chlamydiae for up to 2 weeks after challenge. In this study, C. trachomatis serovar D recombinant proteins, such as recombinant major outer membrane protein (rMOMP), recombinant inclusion membrane protein A (rIncA), and rCPAF were administered intranasally, individually or in combinations, with murine interleukin-12 (IL-1
