A vaccination model for COVID-19 in Gauteng, South Africa [PDF]
Infectious Disease Modelling, 2022 The COVID-19 pandemic provides an opportunity to explore the impact of government mandates on movement restrictions and non-pharmaceutical interventions on a novel infection, and we investigate these strategies in early-stage outbreak dynamics.
