Safeguarding against chlamydia

Chlamydia trachomatis is a formidable foe. It's the most common sexually transmitted pathogen, infecting more than 100 million people each year. In the developing world, chlamydial infection is the leading cause of preventable blindness. Around the world, it ranks as the number one cause of infertility and ectopic pregnancy. A vaccine that generates two waves of protective immune cells needed to eliminate chlamydial infection has been developed by researchers.
