Improving vaccination coverage: the experience of the Expanded Programme on Immunization in Vanuatu.
This paper looks at the success of measures adopted to improve vaccination coverage of infants in the Republic of Vanuatu. In 1982 the Department of Health introduced an Expanded Programme on Immunization (EPI). Since the republic has over 80 inhabited islands, a scattered population, rough terrain and a lack of transport and communications infrastructure, achieving a high vaccination coverage rate proved difficult. Coverage of infants remained low until 1987. From that year onwards various strategies were employed to increase coverage, including 1) adopting the WHO-recommended diphtheria-pertussis-tetanus (DPT) and oral polio vaccine (OPV) vaccination schedule (6, 10 and 14 weeks) instead of the former schedule (3, 6 and 9 months); 2) improving the training, support and supervision of staff delivering maternal and child health (MCH) services; and 3) improving community involvement through social mobilization activities in areas of low coverage. Data on vaccination coverage of infants for the period 1984 to 1990 were compared. Over this period coverage of infants with 3 doses of DPT rose from 29% to 76%, with 3 doses of OPV from 29% to 78%, and with measles vaccine from 19% to 66%. These dramatic improvements have largely occurred since 1987. The results demonstrate the success of the measures adopted, and the experience of Vanuatu offers lessons in improving vaccination coverage for other countries in the region.
