Genocea is developing a new class of human vaccines based on a revolutionary platform for the rapid discovery of antigens that induce T cell immunity. The platform, which dramatically reduces the time to discover vaccine candidates, uniquely employs a proprietary, high-throughput approach that mimics the natural immune response in the laboratory to comprehensively screen for antigens that are protective across diverse human populations. Genocea has demonstrated preclinical proof-of-concept with vaccines for herpes simplex virus type 2 (HSV-2), pneumococcus, and Chlamydia trachomatis, infections that affect hundreds of millions of people worldwide.
