Vaccine delivery management.
During the typical 12- to 18-month voyage of a vaccine from manufacturer to immunization site, many situations arise in which the cold chain may be interrupted. Extensive efforts have been made in the 1980s to ensure an uninterrupted cold chain through the use of improved equipment and better training of personnel. One important advance is the vaccine cold-chain monitor, which identifies weak spots in the cold chain and prevents the use of heat-damaged vaccine. Further improvements will require efforts by the recipient countries (e.g., better use of the private sector for transport and equipment management), by donor agencies (e.g., greater consideration of the operational and maintenance costs of the equipment selected and resolution of fuel shortages), and by industry (e.g., more appropriate packaging and pricing of vaccine, extension of the expiration period, and increased heat stability.
