GUÍAS DE MANEJO CLÍNICO: Consenso de Meningitis

Nowadays, several vaccines have been developed for the prevention of bacterial infections, and also for prophylaxis. In the 80's of the twentieth century came the first vaccine against Haemophilus influenzae type b, which reduced and virtually eliminated invasive disease by this bacterium. In early 2000, there was a dramatic reduction in invasive pneumococcal disease, with the introduction of PCV-7 vaccine against this germ. However, there were serotypes not included in the vaccine, which was developed by the Phido-CV 10 and PCV-13, 10 and 13 serotypes, respectively. Against meningococcus, polysaccharide vaccines have been developed that have demonstrated effectiveness, as well as the conjugate vaccines, which may be monovalent and tetravalent. Chemoprophylaxis is indicated in specific cases that are reviewed in detail in this chapter.
