This led to development of a 13-valent S pneumoniae polysaccharide conjugate vaccine which is marketed as Prevnar13. The pneumococcal conjugate vaccine PCV13. Two classes of pneumococcal vaccines are currently available one based on polysaccharides and the other based on polysaccharides conjugated to a carrier protein.
Two Streptococcus pneumoniae vaccines are available. Prevnar13 developed by conjugating CPSs of 1 3 4 5 6A 6B 7F 9V 14 18C 19F 19A and 23F to diphtheria toxoid CRM197 15 provided effective memory responses and increased immunogenicity in children under 2 y of age 16. Both the 23-valent Spn polysaccharide vaccine PPV and 7 10 or 13-valent Spn conjugate vaccines PCV-7 10 -13 are serotype-based vaccines and therefore they elicit only serotype-specific immunity.
Their use can prevent some cases of pneumonia meningitis and sepsis. Streptococcus pneumoniae bacteria also called pneumococcal bacteria pneumococci plural and pneumococcus singular are one of the leading causes of illness in young childrenAt least 90 types of pneumococcal bacteria are known to exist. People with pneumococcal disease can spread the bacteria to others when they cough or sneeze.
