Pushing the Boundaries of What’s Possible

Despite widespread vaccination with current pneumococcal conjugate vaccines (PCVs), there is an abundance of non-vaccine strains of the Streptococcus pneumoniae bacteria causing significant morbidity and mortality, underscoring the importance of advancing our lead program, VAX-24, a 24-valent PCV candidate. VAX-24 is currently the broadest-spectrum PCV in development and one of the most complex biologics ever created.

Re-Engineering How Vaccines are Made

We strive to overcome the limitations of conventional, cell-based vaccine approaches using advanced chemistry and modern synthetic techniques – including our XpressCF™ cell-free protein synthesis platform – to produce broad-spectrum vaccines that are uniquely capable of breaking down bacteria’s complex defense mechanisms while preserving immunogenicity.

Building a Pipeline of High-Fidelity and Broad-Spectrum Vaccines

Our PCV franchise is intended to improve upon existing pneumococcal vaccines by covering the serotypes responsible for most of the remaining pneumococcal disease currently in circulation. Following VAX-24, we are developing VAX-XP, a PCV candidate with an expanded breadth of coverage of greater than 30 strains of pneumococcal disease. Additional vaccine candidates in preclinical development target Group A Strep bacteria and periodontitis.
