The MLM modules, developed in 2004 by the WHO/AFRO and partners, are used in EPI MLM courses to train national EPI managers, teachers, students and WHO/UNICEF and other key immunization partners at central, provincial and district levels. The problem-solving approach is the basic teaching method used in all the modules.
The modules were updated in 2011 to incorporate new policies and technologies and will be available from 2012 in English, French and Portuguese.
