[The therapeutic efficacy of a gonococcal vaccine]

The therapeutic efficacies of 2 gonococcal vaccines are compared. One of them is made from gonococcal strains selected for their antigenic characteristics, the other is a commercial vaccine prepared from a random sample of gonococcal strains. The studies have demonstrated a higher therapeutic efficacy of the former vaccine. This fact calls for the creation at production centers of permanent collections of antigenically full-value gonococcal cultures; such collections will help improve the gonococcal vaccine, standardize it, and enhance its biological activity.
