The Vaccine Presentation Assessment Tool (VPAT) was developed by Andrew Garnett through a project of the PATH Malaria Vaccine Initiative (MVI), with financial support from the Bill & Melinda Gates Foundation.

The VPAT was originally designed for malaria vaccines; it was subsequently extended for use with other new vaccines, with financial support from the GAVI Alliance.

The Vaccine Presentation Assessment Tool is designed to model the logistical and financial impact of adding a new vaccine to an immunization schedule. The output from the tool will provide an analytical basis to support collaborative evidence-based discussions on these impacts, internally within the public sector, and externally with vaccine manufacturers and with target countries.

This post-introduction evaluation (PIE) tool provides a systematic method for evaluating the impact of the introduction of a vaccine on the existing immunization system in a country. The PIE tool is designed for immunization managers in countries that have introduced a new or underutilized vaccine. WHO recommends that all countries which have introduced a new vaccine conduct a PIE. Conducting a PIE is not a new concept, and there are several examples of evaluations of Hepatitis B (HepB) and Haemophilus influenzae type b (Hib) vaccine introductions — those experiences have been incorporated into this tool. The purpose of the current tool is to provide a systematic method of performing the evaluation, that is comparable across countries, to facilitate the sharing of experiences.

The Vaccine Volume Calculator has been designed to estimate the net storage volume of vaccines per child.

It is specifically used to analyze how changes to the national immunization programme schedule (introduction of a new vaccine, changes in vaccine formulation/presentation, etc.) will affect cold chain capacity.

English and French versions, and further information available on:
http://www.who.int/immunization_delivery/systems_policy/logistics/en/index4.html

Features:

• Updated information on all vaccines from all pre-qualified manufacturers (type, presentation, packed volume, VVM, etc.)
• Maximum packed volume per vaccine dose
• Estimating net storage volume for vaccines per child
• Estimating net storage volume of diluents & safe injection equipment per child
• Estimating the weight of safe injection equipment per child
• Estimating the amount of injection waste generated per child
• Graphic illustration of results from analysis of vaccines introduction
• vGraphic illustration of results from analysis

The present tool is designed to guide the process of forecasting the needs for vaccines, safe injections equipment as well as cold chain and ambient storage capacities for national immunization programmes.

It provides two options for analysis: scenarios analysis and multi year forecast of needs.

1. The scenario analysis is conducted when the programme is undertaking changes in selection of the  vaccine product in terms of formulation and/or presentation. 
2. The multi year forecast is conducted once decision is made to define the needs for the coming next years.

Features:

• Plans for Routine Vaccination
• Plans for Supplementary Vaccination
• Planning data for national and intermediate vaccine stores
• Forecast of Imm. Supplies & Storage Capacities for Routine at national level
• Forecast of Immunization Supplies & Storage Capacities for SIAs
• Forecast of Vaccines, Safe Injection Supplies & Storage Capacities
• Forecast of Immunization Supplies & Storage
• Capacities for Routine at Intermediate stores
• Forecast of Vaccines, Safe Injection Supplies & Storage
• Capacities for Supplementary Vaccinations at Intermediate
• Level Summary of additional cold chain & vaccine shipment/transport needs for national & intermediate stores
• Cold chain capacities required at the national/primary vaccine store
• Cold chain capacities required at the sub-national/intermediate vaccine stores
