Vaccines for the developing world: current status and future directions

Developing country infectious disease problems differ substantially from those in the industrialized world, and a major effort must be made to devote necessary resources to development of vaccines for the bulk of human infectious disease suffering. At the same time, the political will must be mobilized, at international and national levels, to obtain the financial support and backing to provide these vaccines for children. Finally, efforts must be made to take advantage of new technologies now being developed which address many of the logistic and programmatic challenges faced by developing country immunization programme delivery systems.
