Every country in the world these days must make smart decisions about how to allocate vaccines and what sort of social distancing to mandate to combat the COVID-19 pandemic.
Scientists from Israel have constructed a model that policymakers can use to simulate their choices and find the optimal one.
“Our model can tell you, for instance, whether it makes more sense to vaccinate the elderly and demand more social distancing from adults or vice versa,” says Dr. Shai Pilosof.
Their model was published recently in the peer-reviewed PLOS Computational Biology.
Every country has different considerations – some have ample supplies of vaccines, while others have only limited supplies.
The new model can help calibrate vaccine deployment and social distancing. For example, according to their model, vaccinating the elderly and imposing social distancing mandates on adults is generally more effective than forcing the elderly to stay home and vaccinating the adults.
Prof. Nadav Davidovitch, says: “the current COVID-19 global situation demands a multi-layered response. Vaccines are an essential component but it is clear that different contexts such as population characteristics and vaccine availability, together with the dynamic changes in disease spread, demand crucial decision-making on strategies and priorities. Our model can be applied by different countries to simulate and optimize responses.”
