The present invention is directed virus-like particles (VLPs) which are useful in immunogenic compositions and vaccines epitopes mediating protection are disclosed. Immunogenic peptides are identified and are displayed on virus-like particles, especially Qbeta, MS2, or AP205 VLPs which provide a potent immunogenic response in a patient or subject and enhanced protection from Ct infection in a patient or subject. Pharmaceutical compositions and vaccines are disclosed as are methods for providing an immunogenic response and/or vaccinating a patient or subject against Chlamydia trachomatis infections.

The present invention describes an efficient vaccine against a Chlamydia trachomatis (Ct). The vaccine is based on recombinant fusion molecules that are capable of generating a high titered neutralizing antibody response that is protective against various Ct serovars. Our invention furthermore describe the combination of these antibody promoting fragments with Ct antigens that are targets for T cells with the aim to provide a vaccine that activate both arms of the immune system.

The present invention relates to methods for the recombinant expression of chlamydia major outer membrane protein (MOMP) comprising transforming a population of E. coli host cells with an expression vector comprising a nucleic acid molecule that encodes chlamydia MOMP and encodes a leader sequence for targeting the MOMP to the outer membrane of the cell, wherein the nucleic acid molecule is operatively linked to a promoter. The method of the invention allows expression of MOMP in the outer membrane of the cell, which leads to protein folding that is more like native MOMP relative to a MOMP protein that is expressed intracellularly. Also provided by the invention are uses of the recombinant MOMP in pharmaceutical compositions and methods for the treatment and/or prophylaxis of chlamydia infection and/or the effects thereof.
