Vaccine Volume Calculator

A tool for cold chain logisticians to prepare a preliminary estimate of national cold chain equipment needs and dry store requirements. It can be used to:

• Assess current needs based on the existing vaccine schedule

• Forecast future needs based on up to four alternative vaccine schedules

• Generate vaccine volume data to help with the planning of supplementary immunization activities (SIAs). Up to four alternative SIAs can be evaluated.

• The tool includes a database of WHO pre-qualified vaccines and a range of pre-qualified vaccine refrigerators and freezers, and passive containers commonly used in the field.

The same calculation principles are used in other tools such as the Supply Chain Sizing Tool and EVM Assessment Tool.
