Vaccines against sexually transmitted infections: an update

Abstract

Abstract Sexually transmitted infections (STI) constitute a major share of the diseases encountered by physicians. Although science has made considerable progress in terms of diagnosing and treating such infections, development of effective and safe vaccines is still needed. Syphilis, viral warts, gonorrhoea, genital herpes, chlamydia and trichomoniasis are the most common infections that are transmitted sexually. In this review, we have attempted to summarize the current status, lacunae and avenues for future research, with reference to the development of STI vaccines.
