Product Description

Meningococcal meningitis caused by the bacterium Neisseria meningitides, is a serious infection of the fluid in the spinal cord and the fluid that surrounds the brain and can result in brain damage and even death. The bacteria are spread by direct close contact with the discharges from the nose or throat of an infected person. Meningococcal meningitis is most common in infants and children. People who have had close or prolonged contact with a patient with meningococcal meningitis are at increased risk. Bacterial meningitis can be treated with antibiotics, but an early diagnosis and treatment is crucial. To prevent the disease, vaccines are the best choice. The vaccine against meningitis consists of highly purified polysaccharides that originate from the Meningococcal bacteria. Currently vaccines are produced against 4 serotypes, called A, C, Y and W**5. The strains used for production are recommended by WHO/NICPBP and provided by NICPBP Tianyuan produces 3 types of polysaccharide meningitis vaccines: one mono-valent: Men A, one di-valent: Men AC, and one tetra-valent: Men ACYW**5 which are filled into vials and lyophilized in freeze-dryers. Tianyuan also provides the reconstitution solution. This process allows an excellent shelf-life of the product. Finally, the vaccine quality is checked and then marketed after approval by the national regulatory authority (SFDA).
