About PriorityVax: A Platform to Support Priority-setting Decisions for Vaccines

PriorityVax is an interactive, online tool to support deliberations and decision-making using evidence-to-recommendation frameworks.

As resources are limited and the costs and range of available vaccines increase, priority setting is needed to help balance the many competing needs within a health system and to equitably and transparently establish how to select appropriate vaccines. PriorityVax has been designed to support decision-making that emphasizes the importance of local context in identifying key criteria for decisions and the evaluation of related evidence.

How it Works

The following videos will introduce the platform, take a quick tour of its background and features, and take you through real-world examples of how the tool has been used by our stakeholders.

Use Case 1: Considering new vaccines for introduction in Uganda

In this use case, we follow the deliberative process of the Uganda National Immunization Technical Advisory Group (NITAG) as they prioritized between new vaccines that were under consideration for introduction to routine immunization. We look at entering evidence gathered through a systematic review and GRADE process and then use PriorityVax to explore opinions within the committee.

Use Case 2: Selection of Pneumococcal Conjugate Vaccine products in Papua New Guinea

In this use case, we compare two Pneumococcal Conjugate Vaccine (PCV) products that were considered for introduction into Papua New Guinea. Comparing different vaccine formulations and profiles is likely an increasing concern for countries that are graduating from Gavi, the vaccine alliance. We additionally review how the tool supports the updating of evidence over time to re-assess prioritization and to explore putative scenarios to reflect future constraints (e.g. costs or storage space requirements).
