Neisseria Meningitidis Serogroup W-135 Tetanus Toxoid Conjugate Vaccine

Published: July 26, 2026Updated: August 29, 2026

This vaccine protects against Neisseria meningitidis serogroup W-135, a bacterial pathogen that causes meningococcal meningitis and septicemia. It is a conjugate vaccine that links capsular polysaccharides to tetanus toxoid protein, enhancing immune response and providing longer-lasting protection compared to plain polysaccharide vaccines. The vaccine is particularly recommended for travelers to regions where serogroup W-135 is endemic or epidemic, including Hajj pilgrims, and for outbreak control situations.

Prevention of invasive meningococcal disease caused by Neisseria meningitidis serogroup W-135, including meningitis and meningococcemia. Indicated for active immunization of individuals traveling to or residing in areas where W-135 is endemic or epidemic, particularly the African meningitis belt, and for Hajj pilgrims (required by Saudi Arabia). May also be used in outbreak situations involving this serogroup.

This conjugate vaccine works by stimulating the immune system to produce antibodies against the polysaccharide capsule of Neisseria meningitidis serogroup W-135. The tetanus toxoid protein carrier converts the T-cell independent polysaccharide antigen into a T-cell dependent antigen, producing a stronger and more durable immune response with enhanced immunological memory. This conjugation technology makes the vaccine effective even in young children.

Common adverse reactions include injection site pain, redness, and swelling; systemic reactions may include headache, fatigue, and mild fever. Contraindicated in individuals with known hypersensitivity to any vaccine component. Safety during pregnancy should be evaluated by a healthcare provider. Vaccination does not provide protection against other meningococcal serogroups. Booster recommendations vary by country and risk factors.
