Mechanism of action

PCV7 works by conjugating polysaccharide antigens from seven pneumococcal serotypes to a protein carrier (diphtheria toxoid), which enhances T-cell dependent immune responses. This conjugation strategy allows the vaccine to elicit both antibody and cellular immunity, providing protection against invasive pneumococcal disease caused by the included serotypes. The vaccine is administered intramuscularly and induces opsonophagocytic antibodies that facilitate bacterial clearance.
