Abstract
Antibody or antigen containing microparticles for the active or passive immunization of the internal female reproductive organs, comprising: microparticles of an antigen or antibody incorporated in a matrix material which is biocompatible and biologically degradable, said microparticles capable of being transported after deposition in the vagina by the natural transport mechanism of the internal female reproductive organs across the cervix into the uterus.
