Meningococcal A conjugate vaccine: updated guidance

In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. A position paper on meningococcal vaccines was published in 2011 and its recommendations remain valid. This update adds to the previous recommendations specifically concerning routine immunization of infants and young children in the African meningitis belt with meningococcal A conjugate vaccine, following discussions at the October 2014 SAGE meeting.
