With a view to improving child health, the Nigerian government has introduced pentavalent vaccine into her routine immunization schedule. Pentavalent vaccine is a combination of five vaccines-in-one that prevents diphtheria, tetanus, whooping cough, hepatitis b and haemophilus influenza type b, all through a single dose.
With this introduction, nearly 400,000 cases of haemophilus influenza type B would be prevented with about 27,000 lives saved annually in Nigeria.
