The Vaccine Impact Modelling Consortium is hosted out of Imperial College and coordinates a number of research groups to model the impact of vaccination programmes worldwide. Within the JHU ID Dynamics group, we contribute to the efforts around cholera, measles and rubella models. Estimates from our models, combined with those from other groups, are used to understand both global and more local level impacts of vaccines and are used regularly to inform policy at organizations like Gavi, the Vaccine Alliance.
