Optimal vaccination in a stochastic epidemic model of two non-interacting populations [PDF]
, 2014 Developing robust, quantitative methods to optimize resource allocations in response to epidemics has the potential to save lives and minimize health care costs. In this paper, we develop and apply a computationally efficient algorithm that enables us to

Herd immunity and epidemic size in networks with vaccination homophily. [PDF]
Physical Review E, 2021 We study how the herd immunity threshold and the expected epidemic size depend on homophily with respect to vaccine adoption. We find that the presence of homophily considerably increases the critical vaccine coverage needed for herd immunity and that ...
