As part of the global drive to achieve Universal Child Immunisation by l990 (UCI9O), Somalia launched a national immunisation programme for women and children. While access to it improved, actual demand for immunisation remained low. This paper reports the findings of a study to identify the factors influencing acceptance of immunisation in two Somali communities. A retrospective, qualitative approach was adopted to assess individual and community experience both with immunisation and with the immunisation programme.
