meningococcal polysaccharide group A, C, Y and W135 conjugate vaccine

The meningococcal ACYW135 conjugate vaccine developed by Shenzhen Mellow Hope Pharm Industrial is a quadrivalent vaccine indicated for the active immunization against invasive meningococcal disease caused by *Neisseria meningitidis* serogroups A, C, Y, and W135. The vaccine consists of purified capsular polysaccharides from each of the four serogroups, which are individually conjugated to a carrier protein. This conjugation process is critical as it transforms the polysaccharides from T-cell independent antigens into T-cell dependent antigens, thereby inducing a more robust immune response, particularly in infants and young children, and promoting the development of long-term immunological memory. This vaccine is part of the developer's portfolio of biological products aimed at preventing life-threatening bacterial meningitis and sepsis.
