    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.

    World Health Organization [WHO]. Expanded Programme on Immunization [EPI]. European Region on Immunization Activities

    [Unpublished] 1984.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.

    Vaccination against tuberculosis. Report of an ICMR/WHO Scientific Group.

    World Health Organization [WHO]. Scientific Group on Vaccines Against Tuberculosis

    WORLD HEALTH ORGANIZATION TECHNICAL REPORT SERIES. 1980; (651):1-19.

    This document reports the discussions of a Scientific Group on Vaccination Against Tuberculosis, cosponsored by the Indian Council of Medical Research and the World Health Organization (WHO), that met in 1980. The objectives of the meeting were to review research on Bacillus Calmete-Guerin (BCG) vaccination, assess the present state of knowledge, and determine how to advance this knowledge. Particular emphasis is placed in this document on the trial of BCG vaccines in South India. In this trial, the tuberculin sensitivity induced by BCG vaccination was highly satisfactory at 2 1/2 months but had waned sharply by 2 1/2 years and the 7 1/2-year follow up revealed a high incidence of tuberculous infection in the study population. It is suggested that the protective effect of BCG may depend on epidemiologic, environmental, and immunologic factors affecting both the host and the infective agent. Studies to test certain hypotheses (e.g., the immune response of the study population was unusual, the vaccines were inadequate, the south Indian variant of M tuberculosis acted as an attenuating immunizing agent, and mycobacteria other than M tuberculosis may have partially immunized the study population) are recommended. A detailed analysis should be made when results from the 10-year follow up of the south Indian study population are available.

    WHO Expert Committee on Tuberculosis: ninth report.

    World Health Organization [WHO]. Expert Committee on Tuberculosis

    WORLD HEALTH ORGANIZATION TECHNICAL REPORT SERIES. 1974; (552):1-40.

    This document represents the work of a World Health Organization (WHO) Expert Committee on Tuberculosis, which met in Geneva in 1973. Chapters in this volume focus on epidemiology, Bacillus Calmette-Guerin (BCG) vaccination, case finding and treatment, national tuberculosis programs, research, WHO activities in this field, and the activities of the International Union against Tuberculosis and voluntary groups. The Committee emphasized that tuberculosis still ranks among the world's major health problems, particularly in developing countries. Even in many developed countries, tuberculosis and its sequelae are a more important cause of death than all the other notifiable infectious diseases combined. The previous WHO report, issued in 1964, set forth the concept of a comprehensive tuberculosis control program on a national scale. The implementation of this approach has encountered many problems, including deficiencies in the health infrastructure of many countries (shortages of financial, material, and physical resources and a lack of trained manpower) and resistance to change. However, many countries have instituted comprehensive programs and tuberculosis control has become a widely applied community health activity. A priority will be control of pulmonary tuberculosis. The Committee stressed that national programs must be countrywide, permanent, adapted to the expressed demands of the population, and integrated in the community health structure. Steps involved in setting up such programs include planning and programming, selection of technical policies, implementation, and evaluation. Research priority areas identified by the Committee include epidemiology, bacteriology and immunology, immunization, chemotherpy, the systems analysis approach to tuberculosis control, and training methods and instructional materials.

    New developments in vaccinology.

    Andre FE

    ANALES ESPANOLES DE PEDIATRIA. 1992 Jun; 36 Suppl 48:189.

    New vaccine developments will reflect achievements of the World Health Organization's (WHO) Expanded Programme on Immunization (EPI), as well as resistance from the public toward increasing numbers of vaccines. WHO's EPI program has concentrated on tuberculosis, diphtheria, tetanus, whooping cough, polio, and measles. 35 countries are attempting to control hepatitis B with universal vaccination. Now some countries are also recommending vaccination against Haemophilus influenza, mumps, and rubella. The complexity of multiple injections has prompted new research on acellular vaccines for pertussis, hepatitis A and B, varicella, and malaria. Combined vaccines and new adjuvants are also targets of intense research. Vaccines are a priority, because they are among the most cost-effective of medical interventions.

    Some clinical aspects of HIV infection in Africa.

    Harries A

    AFRICA HEALTH. 1992 Jul; 14(5):10-1.

    An update on clinical aspects of HIV in africa highlights new proposed clinical definitions of adult AIDS and of tuberculosis in HIV+ adults, and staging of adult HIV infection. The 1986 WHO clinical definition of AIDS has been widely used in Africa, but now research suggests that this definition has several limitations: the definition will pick up several unrelated diseases such as diabetes mellitus and renal failure. It does not ascertain cases of AIDS marked by nonopportunistic infections. Most persons with pulmonary tuberculosis may be wrongly diagnosed with AIDS by this definition. The study showed that the WHO clinical definition has good specificity and positive predictive value for HIV+ people, but its positive predictive value fell to 30% in identifying people with AIDS in Africa. New definitions should take into account any serious morbidity, tuberculosis, neurological disease, both endemic localized Kaposi's, and aggressive typical Kaposi's sarcoma, and HIV serological testing. Tuberculosis is a problem because few HIV+ people suspected of having pulmonary TB (sputum-negative TB) actually have it based on bronchoscopy, while HIV+ persons with TB experience high mortality, often from pyogenic bacteremia. HIV+ persons with TB suffer high rates of relapse, possibly related to insufficient drug treatment or reinfection. 1 study showed that 6 months of isoniazid significantly improved incidence of TB over 30 months of follow-up. Staging of AIDS in Africa based on degree of immunosuppression was proposed as: 1) clinically inapparent HIV infection marked by pulmonary TB, soft tissue infections, and community acquired pneumonia; 2) lymphadenopathy, oral thrush, widespread pruritic maculopapular rash, herpes zoster, enteric illness, dysentery, and Kaposi's sarcoma; and 3) HIV wasting syndrome, chronic pulmonary disease, meningitis, and fever of unknown origin.

    EPI target diseases: measles, tetanus, polio, tuberculosis, pertussis, and diphtheria.

    Rodrigues LC

    In: Disease and mortality in Sub-Saharan Africa, edited by Richard G. Feachem, Dean T. Jamison. Oxford, England, Oxford University Press, 1991. 173-89.

    In Sub-Saharan Africa (SSA), 1% of all children die of neonatal tetanus, 9% of measles, 3% of tuberculosis (TB), and 4% of pertussis. Further, .6% acquire paralytic polio. 20% of the .6% who acquire diphtheria die. Even though vaccination can control these diseases, only 20% of children in SSA receive the complete course of vaccination against the 6 diseases targeted by WHO's Expanded Programme on Immunization (EPI). But high vaccine coverage is not always a cure-all. For example, in the Gambia coverage is high but high mortality levels persist. Of the EPI diseases, measles is the greatest threat since it kills 2 million people annually in developing countries. Measles related mortality is highest in the 9 months following the disease. Even though tetanus is a major cause of death in neonates, tetanus also kills adults such as those that work with the land. Further the tetanus vaccination is effective in adults, but no adult program operates in SSA. Trained midwives reduce neonatal tetanus mortality by 76.6% and vaccination of pregnant mothers with 2 doses of tetanus toxoid reduces mortality 93.3%. Lameness surveys in SSA countries show that, contrary to earlier beliefs, paralytic polio is quite common (range 0.7-13.2). Administration of the oral polio vaccine and improved sanitation are responsible for a real fall in polio cases in the Gambia, the Ivory Coast, and Cameroon. TB was introduced into SSA in the 19th century. It mainly occurs in adults. The estimated life long risk of developing smear positive TB in SSA is 63. The case fatality rate of pertussis in the 1st year of life is high (3.2) and infants do no acquire maternal immunity against it, so the best control measures are early vaccination and identifying secondary cases among young siblings. Of the EPI diseases, scientists know the least about diphtheria in SSA. Its case fatality rate is high (11-38%) yet it is treatable. Primary problems of adequate vaccination coverage for the EPI diseases are managerial problems rather than technological.

    Vaccination strategies in developing countries.

    Poore P

    VACCINE. 1988 Oct; 6(5):393-8.

    In developing countries, where economic development is lacking and literacy rates are low, priority must be given to primary health care and to the establishmend of sustainable health care delivery systems. The World Health Organization's Expanded Program of Immunization was designed with the goal of immunizing all children against measles, pertussis, tetanus, poliomyelitis, tuberculosis, and diphtheria by 1990. A second function of the immunization program is to establish a health care delivery system. Today 50% of infants receive 3 doses of diptheria/pertussis/tetanus and polio vaccines, and 70% receive at least 1 dose. Measles kills 2 million children every year. The standard strain of attenuated vaccine is given at 9 months, and 1 dose protects 95% of children for life. Tetanus kills 800,000 infants every year. The vaccine must be refrigerated, and 2 doses are essential. Tuberculosis kills 2 million children under 5 every year. The attenuated BCG vaccine should be given at birth, and a single dose confers some protection. Diphtheria is most common among poor, urban children in termperate climates, and 3 doses of toxoid at monthly intervals are recommended. Poliomyelitis paralyzes 250,000 children a year. 4 doses of live attenuated Sabin vaccine are recommended. The vaccine is very sensitive to heat. Other vaccines in use or being developed include yellow fever, meningococcus, Japanese B encephalitis, rubella, hepatitis B, cholera, rotavirus, pneumonococcus, and Haemophilus influezae. 2 problems that confront the delivery of health services, including immunization, are lack of funds and lack of access to susceptible populations. Approaches to the lack of funds problem include fee for service, taxation, beter management of existing resources, reallocation of health resources, and increased funding from donor nations. Approaches to the problem of access include vaccination whenever children come into contact with a health facility for any reason, channeling by members of the community, involvement of traditional healers and birth attendants, outreach services, mass campaigns, pulse technics, and financial incentives.

    Diarrheal diseases morbidity, mortality and treatment rates in Bahrain (1986).

    Al-Khateeb M

    [Unpublished] 1988. Presented at the 13th World Conference on Health Education, Houston, Texas, August 28 - September 2, 1988. 60 p.

    This study is the report of a 1986 baseline survey, guided by the World Health Organization's "Guidelines for a Sample Survey of Diarrheal Diseases Morbidity, Mortality, and Treatment Rate." The survey method was the Expanded Program on Immunization 30 cluster 2-stage method. Baseline data were also gathered on the status of immunization against diphtheria, tetanus, whooping cough, poliomyelitis, measles, and tuberculosis. Primary health care services in Bahrain are generally good. The archipelago of 670 sq km has a population of 417,210 including 55,000 children under 5. There are 18 health centers and 480 physicians or 1 physician for every 860 people. All inhabitants of a catchment area live within 5 km of a health center, and medical care is free. Diarrhea is due to a number of different organisms, including typhoid, paratyphoid, salmonellosis, Escherichia coli, rotaviruses, and giardiasis, but there has been no cholera in Bahrain since 1979. The national diarrheal diseases control program, drafted by the World Health Organization in 1985, emphasized the use of oral rehydration therapy, breast feeding, and feeding during diarrhea. No vaccinations are compulsory in Bahrain, but immunization coverage has been reported annually since 1981, and vaccinations are in line with the World Health Organization's criteria. Diphtheria-Typhoid-Paratyphoid vaccinations were 1st given in Bahrain in 1957; polio vaccination began in 1958 with Salk vaccine and in 1962 with the Sabin vaccine. Measles vaccination began in 1974. BCG vaccination has been given to children entering school since 1972. All health centers in the country offer vaccination services. Vaccines are stored under refrigeration, and the central supply is at the Public Health Directorate. Adverse effects of vaccinations are monitored. The 1986 diarrheal diseases survey, using the 30 cluster method, looked at a sample of 4114 children under 5 from 2515 households. 378 (9.2%) of the children suffered from diarrhea, and 200 (52.9%) were treated with oral rehydration salts. The under-5 diarrheal mortality rate was .97/1000. The estimated number of episodes of diarrhea per child per year is 2.4, with a high of 8.7 episodes in the Northern Region and a low of 1.2 episodes in the Muharraq Region. Vaccination coverage of children under 2 for other diseases was found to be 96.5% for diphtheria, paratyphoid, and typhoid; 95% for polio; 82.5% for measles; and 59.8% for the trivalent mumps, measles and rubella vaccine. 96.4% of all vaccinations were given in government hospitals. 98.7% of mothers have been examined during pregnancy, and 98.9% of all deliveries are in hospitals. It is recommended that a health education campaign be concentrated on diarrhea, breast feeding, feeding during diarrhea, and hygiene; that both medical staff and mothers be trained in the use of oral rehydration salts; that they should also be informed of the adverse effects of treating diarrhea with antibiotics; that a system for reporting cases of diarrhea be developed; that health education campaigns emphasize the importance of receiving booster doses of vaccines and of vaccination against measles; that staff at health centers adjust their schedules so as to be available for immunizations as needed; and that this survey be repeated every 2 years.

    A perspective on controlling vaccine-preventable diseases among children in Liberia.

    Weeks RM

    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.

    Local Area Monitoring (LAM).

    Kirsch TD

    WORLD HEALTH STATISTICS QUARTERLY. RAPPORT TRIMESTRIEL DE STATISTIQUES SANITAIRES MONDIALES. 1988; 41(1):19-25.

    Routine surveillance of the incidence of vaccine-preventable diseases has not proved sensitive enough to demonstrate the impact of the Expanded Program on Immunization (EPI) in many countries. In order to document progress since the start of the EPI in 1979, data are needed for several years prior to that. In most developing countries these can be found only in major cities or large hospitals. Therefore a system of sentinel surveillance, the Local Area Monitoring Project (LAM), is being set up in selected institutions in the major cities of the developing world. The primary goal of the LAM project is to provide disease-incidence data of sufficient quality to evaluate more fully the global impact of the EPI on the 6 target diseases--diptheria, pertusis, tetanus, poliomyelitis, measles, and tuberculosis. The goal is to include the major city of each of the 25 largest developing countries, with a total population of 115 million. These 25 countries together account for 85% of all births in the developing world. The program and coverage information is used to assess the impact of individual EPI programs on disease trends. Preliminary analysis of the 12 cities with the best data suggests that the impact of the EPI on the incidence of the target diseases has been greater than previously shown by the routine system. The LAM information is useful for global and regional analysis of program impact, but for the countries themselves its utility may be even greater. It is hoped that the project will help to improve a country's surveillance system by encouraging the use of sentinel reporting as a means of supplementing routine data. The information on the impact of the EPI may further increase political and public support for a program. (Summaries in ENG, FRE)
