The guidance is designed as a resource to assist stakeholders involved in immunization decision making – including RITAG and NITAG members, EPI managers, immunization technical working group members, and technical partners who support immunization policy decision-making – in interpreting and applying model estimates.
This guidance was developed by the Department of Immunization, Vaccines and Biologicals at the World Health Organization (WHO) and the WHO Immunization and Vaccines Related Implementation Research Advisory Committee (IVIR-AC).
