Report of the European Region on Immunization Activities. (Global Advisory Group EPI, Alexandria, October 1984). WHO/Expanded Immunization Programme and the European Immunization Targets in the Framework of HFA 2000.
[Unpublished] 1984. Presented at the EPI Global Advisory Group Meeting, Alexandria, Egypt, 21-25 October 1984. 3 p. (EPI/GAG/84/WP.4)Current reported levels of morbidity and mortality from measles, poliomyelitis, diphtheria, tetanus, and tuberculosis in most countries in the European Region are at or near record low levels. However, several factors threaten successful achievement of the Expanded Program on Immunization (EPI) goal of making immunization services available to all the world's children by the year 2000, including changes in public attitudes as diseases pose less of a visible threat, declining acceptance rates for certain immunizations, variations in vaccines included in the EPI, and incomplete information on the incidence of diseases preventable by immunization and on vaccination coverage rates. To launch a more coordinated approach to the EPI goals, a 2nd Conference on Immunization Policies in Europe is scheduled to be held in Czechoslovakia. Its objectives are: 1) to review and analyze the current situation, including achievements and gaps, in immunization programs in individual countries and the European Region as a whole; 2) to determine the necessary actions to eliminate indigenous measles, poliomyelitis, neonatal tetanus, congenital rubella, and diphtheria; 3) to consider appropriate policies regarding the control by immunization of other diseases of public health importance; 4) to strengthen existing or establish additional systems for effective monitoring and surveillance; 5) to formulate actions necessary to improve national vaccine programs in order to achieve national and regional targets; 6) to reinforce the commitment of Member Countries to the goals and activities of the EPI; and 7) to define appropriate activities for the Regional Office for Europe of the World Health Organization to achieve coordinated action.
Report of the third meeting of the scientific working group on viral diarrhoeas: microbiology, epidemiology, immunology and vaccine development, [held in] Geneva, 1-3, February 1984.
Geneva, Switzerland, WHO, . 19p.The current status of the Scientific Working Group Program is reviewed, showing an expansion of activities in both its health services component (planning, implementation and evaluation of national diarrheal diseases control programs) and its research component (biomedical and operational). Submission of research proposals is encouraged by the Steering Committee (SC), namely those investigating the etiological role of viral agents in diarrheal disease and the epidemiology of these agents. Recently, the SC has made a particular effort to stimulate research in the area of immunology of viral enteric infections, which has been a generally neglected area. Other important areas of Program activity include site visits to review progress made by its projects, to participate in the initial design or the analysis of studies, or to stimulate general interest among research workers in the activities of the SWG. Workshops have also been initiated and conducted in WHO regions. The SWG notes with satisfaction the progress of the Program and commends the SC's efforts to stimulate and support research activities. SWG recommendations bear on the need for more data on the etiology and epidemiology of diarrhea in the community and the encouragement of further community-based studies. Particular attention should also be given to the preparation of reagents for the serotyping and subgrouping of rotaviruses. Moreover, the Group recommends that research strengthening workshops be continously held. In addition to the review of the meeting and recommendations, this paper includes a report on active and passive immunity to viral diarrheas. Special attention is given to rotavirus diarrhea as it tends to be common and quite severe. Its epidemiology is briefly presented, showing its incidence, seasonality (winter) in temperate climates, age-specific occurrence (most severe in infants and young children) and transmission (fecal-oral, person-to-person). Neonatal ans sequential postneonatal rotavirus infection are addressed ans issues for further investigation clarified; e.g., the relationship between low birth weight and the occurrence and severity of infection. Much remains to be elucidated regarding the serotyping-specific epidemiology of rotaviruses. The Group notes that further immunological studies of rotaviruses are essential to elucidate the role of passive protection. The other area of study in which research activities need to concentrate is vaccine development.
INFECTION CONTROL. 1984 Nov; 5(11):538-41.In 1978 the Ministry of Health and Social Welfare (MHSW) of Liberia launched the Expanded Program on Immunization (EPI) with the 5-year objective of establishing an 80% reduction in child mortality and morbidity from measles, polio, diphtheria, neonatal tetanus, pertussis, and tuberculosis. The program at first adopted a strategy of using 15 mobile units in 11 operational zones to deliver vaccinations throughout the country. However, by 1980, despite support from the Baptist World Alliance, the UN International Children's Emergency Fund (UNICEF), and the World Health Organization (WHO), it became evident that the mobile strategy was neither economically feasible nor practical. Therefore, with support from the US Agency for International Development (USAID), the EPI shifted to a strategy of integrating immunization activities into the existing network of state health facilities. After 5 years, in 1982, the Program was evaluated by a team from the MHSW, WHO, USAID, and the Centers for Disease Control. The evaluating team felt that the EPI's strategy was good, but its goals were not being achieved due to deficiencies in funding, clinic supervision, and rural community outreach, as well as shortages of kerosene and spare parts needs to keep the essential refrigerators in operating condition. Measles remains endemic; in the capital, Monrovia, only 9% of the children have been vaccinated against it. Immunization coverage is particularly low in the capital the countries. Other reasons for low vaccination coverage in Liberia are lack of community awareness of existing facilities and the importance of vaccination and lack of coordination at the community level to use the existing facilities efficiently. International assistance is still needed, especially to develop heat-stable vaccines, so that maintenance of refrigerators will not be necessary.
EPI in the Americas. Report to the Global Advisory Group Meeting, Alexandria, Egypt, 22-26 October 1984.
[Unpublished] 1984. 15 p.This discussion of the Expanded Program on Immunization (EPI) in the Americas covers training, the cold chain, the Pan American Health Organization's (PAHO) Revolving Fund for the purchase of vaccines and related supplies, evaluation, subregional meetings and setting of 1985 targets, progress to date and 1984-85 activities, and information dissemination. All countries in the Region of the Americas are committed to the implementation of the EPI as an essential strategy to achieve health for all by 2000. During 1983, over 2000 health workers were trained in program formulation, implementation, and evaluation through workshops held in Argentina, Brazil, Cuba, El Salvador, and Uruguay. From the time EPI training activities were launched in early 1979 through 3rd quarter 1984, it is estimated that at least 15,000 health workers have attended these workshops. Over 12,000 EPI modules have been distributed in the Region, either directly by the EPI or through the PAHO Textbooks Program. The Regional Focal Point for the EPI cold chain in Cali, Colombia, continues to provide testing services for the identification of suitable equipment for the storage and transport of vaccines. The evaluation of solar refrigeration equipment is being emphasized increasingly. PAHO's Revolving Fund for the purchase of vaccines and related supplies received strong support from the UN International Children's Emergency Fund (UNICEF), which contributed US $500,000, and the government of the US, which contributed $1,686,000 to the fund's capitalization. These contributions raise the capitalization level to US $4,531,112. Most countries are gearing their activities toward the increase of immunization coverage, particularly to the high-risk groups of children under 1 year of age and pregnant women. To evaluate these programs, PAHO has developed and tested a comprehensive multidisciplinary methodology for this purpose. Since November 1980, 18 countries have conducted comprehensive EPI evaluations. 6 countries also have had followup evaluations to assess the extent to which the recommendations from the 1st evaluation were implemented. At each subregional meeting, participants met in small discussion groups to review each other's work plans and discuss appropriate targets for the next 2 years. Immunization coverage has improved considerably in the Americas over the last several years. Figure 2 plots the incidence rates of polio, tetanus, diphtheria, whooping cough, and measles from 1970-83 in the 20 countries which make up the Latin American subregion. If all countries meet their 1985 targets, immunization coverages for DPT and polio will range from 60-100%, with most countries attaining coverages of over 80%. For measles, 1985 targets range from 50-95%, and from 70-99% for BCG. The main vehicle for dissemination of information is the "EPI Newsletter," which publishes information on program development and epidemiology of the EPI diseases.
