Optimal allocation of COVID-19 Vaccines in West Africa | A Shiny success story
summary
A Shiny app using lpSolve linear program allocates four vaccine types across thousands of sites, optimizing batch-by-batch allocation to maximize vaccinated people while minimizing wastage and honoring constraints like expiration, travel time, site cold storage and available staff. The prototype models a 30 day allocation window by default, shows per-site doses (examples: 722 Sinopharm, 916 Pfizer), lets users toggle mobile sites, and exports tabular distributions. Tool awaits country training and handoff but ministry engagement and iterative data collection are already in place.
