COVID-19 Vaccinations by Town

The dashboard shows COVID-19 vaccination progress in the state of Connecticut. Outlined in orange are towns where social vulnerability index (SVI) in at least one of the census tracts is greater or equal to 0.75. The SVI is an index developed by the CDC to measure potential negative effects on communities caused by external stresses on human health. Such stresses include natural or human-caused disasters, or disease outbreaks.
