Nigeria is often referred to as the “Giant of Africa” due to its large population and economy. The country is the most populous nation on the continent with over 185 million people.

Nigeria has some of the highest under-five mortality rates and some of the lowest vaccination rates in the world. About 25% of these deaths could be prevented through routine immunization.

Weak cold chain infrastructure and inefficient vaccine distribution systems are some of the key immunization program challenges in Nigeria. The Bill and Melinda Gates Foundation invited Project Last Mile to support Lagos State in improving cold chain equipment maintenance practices to make life-saving vaccines more regularly available.
