Where seniors remain vulnerable to the coronavirus

By the numbers: More than two-thirds of residents 65 and older have received at least one dose of the vaccine in every state. But some states are much closer than others to universal vaccination among seniors. States in the Northeast, including Vermont, Rhode Island and Massachusetts, have the highest vaccination rates among seniors. Southern states — like Alabama, Mississippi and Tennessee — have some of the lowest. Yes, but: Some states have done a worse job vaccinating seniors than their overall populations, and a state's political leaning isn't necessarily an indicator of how many seniors have gotten their shots.
