Prevenar 13

Prevenar 13® is a highly advanced, 13-valent pneumococcal conjugate vaccine engineered by Pfizer to defend against invasive diseases caused by Streptococcus pneumoniae. Delivered as a sterile, preservative-free 0.5ml suspension in a pre-filled syringe, it links bacterial capsular polysaccharides from thirteen specific serotypes to a specialized $\text{CRM}_{197}$ carrier protein. This conjugate formulation is crucial because it triggers a robust, T-cell-dependent immune response, ensuring long-lasting memory defense even in infants and young children. Administered via intramuscular injection, Prevenar 13® is clinically essential for protecting vulnerable populations against severe illnesses like pneumonia, meningitis, and acute otitis media.
