Pneumococcus

The pneumococcus bacterium (Streptococcus pneumoniae) kills approximately 500,000 children less than five years of age each year, mainly in the developing world. It is the leading cause of childhood pneumonia, the number one killer of children under five in the developing world, and a cause of meningitis (inflammation of the covering of the brain), ear infections, and bacteremia (blood stream infection). Pneumococcal disease can be treated with antibiotics; however, antibiotic-resistant strains are becoming more common worldwide. Current pneumococcal vaccines approved for use in children are effective against strains common in the industrialized world and some developing countries, but do not cover all 90+ pneumococcal serotypes and they are complex and expensive to manufacture. There are several additional vaccines in development.
