UNICEF is one of four partners spearheading the Global Polio Eradication Initiative and is the lead for vaccine supply and polio communication and social mobilisation activities. UNICEF’s current communication strategies target individual caregivers with information about Polio and the Oral Polio Vaccine (OPV), and there is a need to expand the strategy to include collective societies (groups and communities) to address perceptions, attitudes and behaviours associated with access to and acceptance of OPV. To engage the ‘hardest to reach’ and tackle the challenges associated with securing support from and within high risk communities, a more granular and nuanced understanding of the socio-cultural realities of these groups is required. Anthrologica is collaborating with UNICEF to provide anthropological insight into two high priority communities: a) Nomadic pastoralist communities in Puntland, Somalia; and b) Pashtun communities in the Federally Administered Tribal Areas, the Central Khyber Pakhtunkhwa, and the South Khyber Pakhtunkhwa. The project will run from March to May 2015.
