ABOUT VIAL

The methodology

Validated inference of adoption likelihood (VIAL) is a methodology pioneered by Dalberg Advisors to better understand country preferences for different health products. VIAL builds on conjoint analysis and specialized survey questionnaires to map and understand country preferences. We then translate country data into scenario forecasts for products, that enable discussion around the potential future market dynamics of a given antigen. The work is done in service of the Bill and Melinda Gates Foundation and Gavi, the vaccine alliance. 

 

The work started in November 2018 focusing on vaccines for human papillomavirus (HPV) and pneumococcal conjugate vaccines (PCV). In May 2019 the work was expanded to rotavirus and and cominations of penta/polio/hexa vaccines.
