Pneumococcal disease is a major cause of morbidity and mortality in infants
and young children worldwide. New pneumococcal conjugate vaccines include
7 to 11 serotypes, which are the most common cause of paediatric disease in
most parts of the world. The efficacy of a 7-valent conjugate vaccine was
97.4% (95% CI, 82.7-99.9) against invasive pneumococcal disease, and 57% (9
5% CI, 44-67) against otitis media, caused by vaccine serotypes. Evidence s
hows that the vaccine has the potential to prevent pneumonia. Pneumococcal
conjugate vaccination has also been shown to reduce nasopharyngeal carriage
of vaccine serotypes (particularly serotypes associated with antibiotic re
sistance). Thus widespread use of pneumococcal conjugate vaccine could subs
tantially reduce the burden of invasive disease and would have the potentia
l to control the global spread of antibiotic resistance in pneumococci.
Conclusion: It is important that these highly effective vaccines should be
made available to children in the developing countries.
