To determine the rankings, Stacker examined data from the CDC’s influenza season vaccination coverage dashboard. Researchers looked at coverage estimates for each state during flu seasons from 2010-11 to 2019-20. States were then ranked by average vaccination coverage through those seasons. More information about the methodology is available here.
Five states with the highest flu shot rates over 10 seasons:
1. Rhode Island — 55.9 percent
2. South Dakota — 55.2 percent
3. Massachusetts — 53.8 percent
4. Maryland — 52.2 percent
5. Connecticut — 51.4 percent
