Multiple antigen vaccine strategies in developing countries.

Abstract
Immunization programs constitute one of the most economical and efficient approaches to preventive medicine in developing countries. Costs can be reduced further by administering several antigens simultaneously. Available evidence suggests it is safe and effective to administer the usual range of antigens utilized in developing countries at one time. Likewise, operational experiences in the past 5 years indicate the delivery of multiple antigens is logistically feasible. Mobile vaccination teams can be expected to reach a high percentage of children and by means of objective screening systems, vaccine wastage and duplication can be avoided without the need for individual immunization records.
