Description

technical field

[0001] The invention relates to vaccines, in particular to a Streptococcus pneumoniae vaccine. Background technique

[0002] Infections caused by pneumococci (pulmonary chain) are a major cause of morbidity and mortality worldwide. Pneumonia, febrile bacteremia, and meningitis are the most common manifestations of invasive pneumococcal disease, while bacterial spread within the respiratory tract can lead to middle ear infection, sinusitis, or recurrent bronchitis. Noninvasive manifestations are usually less severe but more common than invasive disease. The likelihood of pneumococcal disease flares during influenza is further increased by the spread of antibiotic-resistant infectious diseases and the fact that pneumococcal pneumonia often follows influenza infection. Diseases caused by Streptococcus pneumoniae have become an important public health problem worldwide. Pneumococcus has become the number one killer of children worldwide.
