Clusters of unvaccinated people in the US

Analyzing county vaccination data from the CDC and state health departments, researchers at Georgetown University found 30 clusters of counties that have lower-than-average vaccination rates, leaving them vulnerable to outbreaks and making them potential breeding grounds for new variants. The five clusters likeliest to have larger populations with low vaccination rates were largely in the Southeastern states.
