PIP: Cuba is about to implement a new plan of action aimed at correcting weaknesses in its immunization program. Components of this plan include: 1) coordination of activities with community organizations to achieve the elimination of measles by 1984; 2) identification of funding sources for the purchase of cold boxes and thermoses to handle vaccines at the local level; 3) coordination with the Ministry of Education to require presentation of a vaccination certificate for entrance into the school system; 4) introduction of rubella and mumps vaccine in the national vaccination schedule; 5) establishment of quarterly program evaluations at the central level to be carried out by the Division of Epidemiology, as well as immunization evaluation at the provincial level as part of the overall effort to decrease infant mortality; and 6) creation of a national multidisciplinary commission to analyze all aspects of the national immunization schedule, including statistical data, control methods, and general program norms. An evaluation of Cuban immunization activities conducted in 1981 concluded that Cuba has made impressive progress in the control of most vaccine-preventable diseases. Factors judged to have contributed to this success include the presence of a single unified health system, active involvement of community organizations, well-staffed statistical services, the high priority accorded immunization activities, a practical system for local health planning, and a system of supervision and evaluation. Most immunizations in Cuba are delivered by local polyclinics, hospitals, or rural health posts. Cuba's epidemiologic surveillance system is among the most reliable in Latin America, and every health care institution telephones reports in daily to the municipality. Only 2 cases of polio have been reported since 1970, and there have been no cases of diphtheria or neonatal tetanus in the last 10 years. Although there has been a marked decrease in measles mortality since immunization began in 1974, morbidity from this disease remains relatively high.
