Vaccinating more people against Covid-19 is always going to be a good thing but the benefits vary widely by state, according to a new computer simulation whose results are charted below. New York would get the biggest reduction in cases from getting 70% of its population fully vaccinated vs. 50%, followed closely by Florida and North Carolina, while South Dakota would see the smallest benefit, the simulation says.

The simulation was performed by Epistemix Inc., a Pittsburgh-based company spun out of the University of Pittsburgh Graduate School of Public Health that performs agent-based modeling. To track epidemics, Epistemix simulates the interactions of millions of imaginary people who are statistically similar to the actual U.S. population, taking into account their demographic characteristics and where they live, work, or go to school.
