Factors to be considered in designing immunization programs in developing countries are summarized. The limiting factors will usually be costs of vaccines, administration equipment and supplies, transport and maintenance of the cold chain. Choices have to be made about the sources of vaccines, whether produced locally or imported, size of vaccine lots and type of package, and quality control of vaccines. Selection of vaccines is treated in a separate appendix, but generally 3 groups are recognized: 1) recommended for general use: smallpox, diphtheria, tetanus, pertussis, BCG, typhoid and measles; 2) recommended for special cases: polio and yellow fever; 3) not recommended for developing countries: rubella, mumps, influenza, cholera; and 4) vaccines in development stage only: arbovirus, rickettsia, trachoma, meningococci, plague and shigella. Schedules for vaccine administration are suggested, such as plans for vaccination every 2 years, plans for 4 courses of vaccinations including 1 at school entry, and special programs such as smallpox campaigns and immunization of adolescent girls and fertile women with tetanus. Finally the importance of recording of vaccinees and assessment of programs is discussed.

The antimicrobial spectrum of azithromycin and clarithromycin suggests a number of further uses for these newer macrolides. Favorable clinical and bacteriologic responses have been reported with both antibiotics in children with community-acquired pneumonia. Response rates were high for overall patient populations and for subgroups with infection caused by Mycoplasma pneumoniae and Chlamydia pneumoniae. Treatment with azithromycin or clarithromycin has resulted in a reduction in mycobacteremia and an improvement in clinical symptoms in adult AIDS patients with disseminated Mycobacterium avium-intracellulare complex. Prophylactic treatment with azithromycin may prevent M. avium-intracellulare complex, especially when combined with rifabutin. Preliminary evidence suggests that both azithromycin and clarithromycin in multidrug combinations may effectively eradicate Helicobacter pylori and that azithromycin may be useful in treating bacterial gastritis caused by Campylobacter species. Trachoma and infections caused by Bordetella pertussis and Ureaplasma urealyticum are other possible future indications for the newer macrolides. Limited clinical evidence also suggests that azithromycin may be effective in the prevention and treatment of malaria.

This article provides background information on bacterial diseases and discusses those that are candidates for elimination or eradication. Only one disease, neonatal tetanus, is a strong candidate for elimination. Others, including Haemophilus influenzae b infection, leprosy, diphtheria, pertussis, tuberculosis, meningococcal disease, congenital syphilis, trachoma and syphilis are important causes of morbidity and mortality in industrialized and developing countries. For all these diseases, eradication/elimination is not likely because of the characteristics of the disease and limitations in the interventions.
