Overview
PG4 is a multivalent pneumococcal conjugate vaccine developed by Pfizer. It is designed to protect against pneumococcal disease, which is caused by the bacterium *Streptococcus pneumoniae*. The vaccine works by presenting specific bacterial polysaccharides, conjugated to a carrier protein, to the immune system, thereby stimulating the production of protective antibodies. Clinical trials are evaluating its safety, tolerability, and immunogenicity in various populations, including adults, toddlers, and infants.
