Nigeria becomes first country to roll out new meningitis vaccine, WHO says

Nigeria has become the first country in the world to roll out the "revolutionary" new Men5CV vaccine against meningitis, the World Health Organization (WHO) said. Nigeria is one of the hotspots of the deadly disease in Africa. Last year, a 50% rise in annual cases was reported across 26 African countries regarded as meningitis hyperendemic countries, according to the WHO.
