What impact has vaccination had on deaths from measles in Sub-Saharan Africa?
In 2011, the World Health Organization (WHO) African Region set a measles elimination goal for 2020. Measles elimination is defined as the absence of endemic measles virus transmission in a region or other defined geographical area for more than 12 months in the presence of a well-performing surveillance system. To meet this goal, vaccine coverage needs to be 95% or higher, with two doses administered per person. However, over the past decade completion of the primary series of infant vaccines in sub-Saharan Africa has stalled at approximately 72%. In 2018, the WHO estimated that 52,600 people died from measles in Africa.
