The first pneumococcal vaccine was developed in the 1980s. They are on the World Health Organization's List of Essential Medicines, the most important medication needed in a basic health system. The wholesale cost in the developing world is about US$17 per dose as of 2014.
A second type of pneumococcal vaccine, known as the pneumococcal polysaccharide vaccine, protects against more types of pneumococcus (23 types), but does not include the harmless protein, so it is mostly used only in older adults or those at higher risk for pneumococcus.he big difference between the pneumococcal vaccine and the Hib vaccine is the number of different types of polysaccharides that need to be included in the vaccine. Whereas, there is really only one strain of Hib that causes disease in children, there are about 90 different strains of pneumococcus.
