Conjugates and reverse vaccinology to eliminate bacterial meningitis.

Bacterial meningitis is caused mainly by Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. Haemophilus influenzae type b vaccines have been extremely successful in eradicating the disease from those countries where the vaccine has been introduced. The recent licensure of the conjugated pneumococcal vaccine suggests that this pathogen also will be soon controlled. Consequently, if we succeed in developing effective vaccines against meningococcus, this will enable us to eliminate bacterial meningitis. The global elimination of bacterial meningitis is a goal which, if appropriate resources are applied, can be reached within the first fifteen years of the 21st century.
