Mechanism of action

Synflorix contains polysaccharide antigens from 13 serotypes of Streptococcus pneumoniae conjugated to a protein carrier (protein D from Haemophilus influenzae type b), which enhances immunogenicity and T-cell dependent responses. The vaccine primes both humoral and cellular immunity to reduce the risk of invasive pneumococcal disease, pneumonia, and otitis media caused by vaccine-covered serotypes.
