Poorest 20% population of West and Central Africa

The group with the lowest measles immunization rate is the poorest 20% population of West and Central Africa because the rates of coverage here were lower for each income group, leaving children mostly not vaccinated.

In addition, it is a sad truth that the global health was directly proportional to the income of the population where the better off families have the complete access to immunization.
