Its purpose is to strengthen open, distance and flexible learning (ODFL) systems and structures to increase access to education for young people living in high HIV prevalence areas in Malawi and Lesotho. It seeks to achieve this through developing a new, more flexible model of education that uses ODFL to complement and enrich conventional schooling. It also seeks to encourage application of the new knowledge generated through effective communication to development agencies, governments, development professionals, non-governmental organisations and other interested stakeholders. Access to education and learning is being viewed as a 'social vaccine' for HIV but in high prevalence areas orphans and other vulnerable children are frequently unable to go to school regularly and are thus being deprived of the very thing they need to help protect themselves from infection. In this context sustained access is critical to long term improvements in risk and vulnerability and it requires new models of education to be developed and tested.
