    Abstract: Described herein are vaccine compositions and methods of selecting an antigen or fragment thereof for the preparation of a vaccine composition. The methods and vaccine compositions described herein are based, in part, on the discovery that certain polypeptides not previously identified or considered for potential use as antigens from pathogenic microorganisms (e.g., N. gonorrhoeae) can provoke an immune response in a subject. The methods of identifying and selecting the antigens described herein rely, in part, on approaches that identify polypeptides (e.g., hypothetical proteins) predicted to be immunogenic.
