Press Release - In a historic move, Nigeria has become the first country in the world to roll out a new vaccine (called Men5CV) recommended by the World Health Organization (WHO), which protects people against five strains of the meningococcus bacteria. The vaccine and emergency vaccination activities are funded by Gavi, the Vaccine Alliance, which funds the global meningitis vaccine stockpile, and supports lower-income countries with routine vaccination against meningitis.
