Wayne State University School of Medicine researcher Judith Whittum-Hudson, professor of immunology and microbiology, internal medicine and ophthalmology, has identified three peptides that have demonstrated a vaccine effect to inoculate against Chlamydia successfully in an animal model. This first-ever vaccine for Chlamydia combats the world's most prevalent sexually transmitted disease and the leading cause of new cases of blindness. "There is no vaccine and the disease is widely rampant," Whittum-Hudson said. "Antibiotics, while effective in treatment, offer no protection against re-infection."
