Vaxcyte is a biotechnology company focused on developing vaccines to prevent bacterial infections. Its pipeline includes VAX-31, a 31-serotype pneumococcal conjugate vaccine candidate that is in Phase 3 for adults and Phase 2 for infants to address invasive disease and pneumonia, and VAX-24, a 24-serotype candidate intended to broaden protection for infants, with VAX-XL in earlier-stage development to extend coverage. The company relies on XpressCF, its cell-free protein synthesis platform licensed from Sutro Biopharma, to accelerate production of complex vaccine antigens. The company operates from San Carlos, California. Its portfolio also includes VAX-A1 for prevention of Group A Streptococcus infections and VAX-GI for Shigella. In June 2026, Vaxcyte dosed its first participant in a Phase 1 study of VAX-A1 in healthy adults.
