Wellstat Vaccines

Wellstat Vaccines is a private U.S. vaccine biotechnology company within the Wellstat group that focused on synthetic and semisynthetic conjugate carbohydrate vaccines for infectious diseases. Publicly available company-profile sources describe programs against meningococcal disease, Haemophilus influenzae type b, Group A and B streptococcal infections, pneumococcal disease, candidiasis, and aspergillosis. Patent activity also indicates work in fungal immunology, including antibodies directed to fungal cell wall polysaccharides. The company appears to have operated from Gaithersburg, Maryland and was part of the broader Wellstat Therapeutics organization. Recent business databases characterize Wellstat Vaccines as no longer active, and no evidence of a current operating corporate presence or commercial products was identified.
