Chlamydia trachomatis: quest for an eye-opening vaccine breakthrough.

INTRODUCTION

Chlamydia trachomatis, commonly referred to as chlamydia (a bacterium), is a common sexually transmitted infection, and if attended to early, it can be treatable. However, if left untreated it can lead to serious consequences. C. trachomatis infects both females and males although its occurrence in females is more common, and it can spread to the eyes causing disease and in some case blindness.

AREA COVERED: With ongoing attempts in the most impoverished regions of the country, trachoma will be eradicated as a blinding disease by the year 2022. A prophylactic vaccine candidate with established safety and efficacy is a cogent tool to achieve this goal. This manuscript covers the vaccine development programs for chlamydial infection.

EXPERT OPINION: Currently, the Surgery Antibiotics Facial Environmental (SAFE) program is being implemented in endemic countries in order to reduce transmission and control of the disease. Vaccines have been shown over the years to protect against infectious diseases. Charge variant-based adjuvant can also be used for the successful delivery of chlamydial specific antigen for efficient vaccine delivery through nano delivery platform. Thus, a vaccine against C. trachomatis would be of great public health benefit.
