Overview PCV20 is a 20-valent pneumococcal conjugate vaccine being developed by AIM Vaccine Co. to prevent invasive pneumococcal disease and pneumonia caused by *Streptococcus pneumoniae*. The vaccine is designed to induce serotype-specific antibody responses by conjugating capsular polysaccharides from 20 different serotypes of the bacteria to a carrier protein. This conjugation converts the polysaccharide into a T-cell dependent antigen, enhancing immunogenicity and inducing immunological memory, which is particularly critical for protection in infants and young children. As of early 2024, the candidate is in the preclinical research stage within AIM Vaccine Co.'s bacterial vaccine platform.
