Vaccine Presentation Assessment Tool: Analytical approach and user guide

The vaccine presentation assessment tool (VPAT) is designed to model the logistical and financial impact of adding a new vaccine to an immunization schedule. The tool can be used in the following ways:

1. To help establish the most suitable format for a novel vaccine by modelling alternative presentations and packaging. Typically this exercise will take place during early discussions between the public sector and the vaccine manufacturer before these critical manufacturing decisions have been finalised.

2. To assess the impact of adding a new vaccine to a schedule, particularly when this vaccine is available on the market in alternative presentations.

3. To analyse the effect of substituting a new vaccine for an existing one—for example, moving from a series of multi-dose single antigen vaccines to a single-dose combination vaccine.

This user guide is to be used with the Vaccine Presentation Assessment Tool (VPAT) Excel model.
