## Abstract

The present invention provides a method of immunizing a host against disease caused by infection by a strain of Chlamydia, specifically C. pneumoniae. The method involves nucleic acid immunization, including DNA immunization, and employs a vector containing a nucleotide sequence which encodes an ATP/ADP translocase of a strain of Chlamydia pneumoniae. The nucleotide sequence is operably linked to a promoter to effect expression of the ATP/ADP translocase in the host. The host may be a human host. Modifications are possible within the scope of this invention.
