Meningokokken
Meningococcal meningitis is a bacterial infection caused by the bacterium "Neisseria meningitidis", also known as meningococcus. The vaccine is made from bacterial capsular polysaccharides through fermentation of each individual serogroup of "Neisseria meningitidis" in bioreactors. After fermentation, the polysaccharides are purified, formulated, and lyophilized using preservatives and stabilizers to make a vaccine product. The vaccine cannot protect from other serogroups of "N. meningitidis" and cannot eliminate the chance of infection by these serogroups.
