Vaccines are only effective if people get them, and the COVID-19 pandemic revealed a real geographic disparity in vaccination rates. Some states are more widely vaccinated than others. To determine which states vaccinate the most, WalletHub compared each state by 16 key metrics—from vaccinated children to people without health insurance to reported measles outbreaks—and assigned each a score on a scale of 100. These are the ten states with the most and least vaccinated populations.
