The HERMES Logistics Modeling Team, consisting of researchers from Pittsburgh Supercomputing Center (PSC), the University of Pittsburgh Swanson School of Engineering and the Johns Hopkins Bloomberg School of Public Health, have used HERMES, their modeling software, to help the Republic of Benin in West Africa determine how to bring more lifesaving vaccines to its children. The team reports its findings this month in the journal Vaccine (The benefits of redesigning Benin's vaccine supply chain, Vaccine, 9 May 2014). Results from the HERMES model have helped the country enact some initial changes in their vaccine delivery system, which may lead to further changes nationwide.
