Pneumococcal polysaccharide vaccine (PPV)
Pneumococcal is a leading cause of serious illness in children and adults throughout the world. The disease is caused by the pneumococcus, which can attack different parts of the human body.
Pneumococcal polysaccharide vaccine is effective against 23 different pneumococcal capsular types (serotypes 1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19F, 19A, 20, 22F, 23F and 33F) and so covers 90 percent of the types found in pneumococcal bacteraemia. This vaccine is widely used in highrisk adults, and has been important reductions in the incidence, morbidity, and mortality from pneumococcal pneumoniae and invasive pneumococcal disease.
CanSino and the partner are co-developing this vaccine product, and try to provide more choices to the emerging markets.
