The transfer of vaccine technology to developing countries. The Latin American experience

Technological advances by developed countries are producing safer, more potent vaccines. In addition, the transfer of the technology of vaccine production to some developing countries has been taking place during the past five decades, thereby making possible the participation of developing countries in the production and supply of the essential biologicals that are required for immunization programs. Examples of successful transfers of technology, the decisive elements and factors that contribute to the transfers, and the major obstacles to such transfers are presented.
