Studies by Aden and Birk demonstrated very high rates of Neonatal Tetanus, Further studies by McElroy failed to confirm neonatal tetanus as a major cause of mortality. Systematic studies of neonatal tetanus are a high program priority. -5- VI Program Management: Somalia will require direct Effective implementation of EPI in all levels of activity.
