Nigeria will be the first country in the world to vaccinate residents aged 1 through 29 years with Men5CV, a novel 1-dose vaccine that protects people from 5 major strains of the meningococcus bacteria (Neisseria meningitidis), the World Health Organization (WHO) announced. The news comes amid a 50% surge in meningitis cases in Africa last year, as well as an uptick in the disease worldwide, including in the US.
