Protecting the Most Vulnerable by Vaccinating the Most Active   [open html - 0B]

From the Webpage: "In this Perspective, the authors used a network simulation model to illustrate five different vaccination strategies for coronavirus disease 2019 (COVID-19), showing that vaccinating the most-active members of the population might be the best way to save lives overall and still protect the vulnerable. Recent models of COVID-19 vaccination have tended not to take into account the person-to-person contact structure that results in the disease's spread. The authors used a model based on a realistic contact network (derived from a data set of 2.2 billion mobile device location points) to run five different vaccination models. What varied between each case was the number of contacts of the people who were vaccinated. [...] The authors found that the high-contact imperfect strategy is at least as effective (and probably more effective) at protecting the vulnerable than direct vaccination and indicates that the United States might be able to provide more protection for vulnerable people by vaccinating people with many contacts than by vaccinating vulnerable people directly."
