A health worker trained through the Uganda Immunization Training Program vaccinates a child.
Although it has long been known that prevention of disease through immunization is one of the most successful and cost-effective public health interventions in history, immunization rates remain low in many parts of the world, particularly sub-Saharan Africa. One major reason for this is limited immunization management capacity in many African countries. In response to this challenge, Merck launched the Merck Vaccine Network-Africa (MVN-A), a ten-year philanthropic initiative that provided customized, hands-on training to immunization managers in Kenya, Mali, Uganda, and Zambia. Between 2003 and 2012, the program trained more than 1,600 vaccine delivery workers.
