Cost-effectiveness of the expanded programme on immunization in the Ivory Coast: a preliminary assessment.

A preliminary calculation was made of the cost-effectiveness of the measles component of the Expanded Programme on Immunization (EPI) in the Ivory Coast. The calculation is based on existing data (program budgets, coverage surveys, counts of vaccinations provided and subjective estimates) and applies to the first three demonstration and training zones (Abidjan, Abengourou and Korhogo) with a combined population of 1.75 million people.

Control of poliomyelitis in Africa.

In Africa, an estimated 168,000 children are disabled by poliomyelitis every year. With the use of lameness surveys to estimate incidence before immunization, surveys to measure vaccination coverage, and surveillance to monitor disease trends, poliomyelitis control in Yaound é, Cameroon; The Gambia; and Abidjan, Ivory Coast was examined. Three doses of oral poliovirus vaccine have been administered to 50%-70% of the children.

[A broad program of vaccination in the Ivory Coast].

This paper is a description of a vaccination programme against the most frequent communicable diseases among children: measles, tuberculosis, diphtheria, tetanus, whooping-cough and poliomyelitis. The programme is to be carried out in three different climate zones (town, forest and savanna) and over a period of six years. The project is supported by US-AID and UNICEF.

Human poxvirus disease after smallpox eradication.

A 5-year-old boy living in a small camp in the rural Ivory Coast had a disease resembling smallpox. This occurred 4 years after smallpox had been eradicated from the Ivory Coast and 1.5 years after the last case of smallpox was detected in West and Central Africa.

Evaluation of a measles-smallpox vaccination campaign by a sero-epidemiologic method.

An assessment technique has been devised whereby children from 30 randomly chosen sampling sites are visited within three days of measles-smallpox vaccination and one month later. Vaccination coverage is measured at house visits and immunologic status is determined by collection of early and late blood samples on filter papers from substratified children in priority age-groups, and by looking at vaccination scars. The methodology was employed in a rural area of the Ivory Coast during the maintenance phase of a measles-smallpox vaccination program; 1762 children from 0--72 months old were inspected.
