Communities with fewer vaccinations seeing significantly higher COVID case rates

A new ABC analysis has found that over the past week, states that have fully vaccinated less than 50% of their total population have reported a weekly average coronavirus case rate that is three times higher than in states that have fully vaccinated more than half of their residents.

States that have fully vaccinated more than half of their residents reported an average of 15.1 new COVID-19 cases per 100,000 people over the last week, compared to an average of 45.1 cases per 100,000 people in states that have vaccinated less than half of their residents.

The 14 states with the highest case rates all have fully vaccinated less than half their total population, and 10 out of the 11 states with the lowest case rates have fully vaccinated more than half of their total population, with the exception being South Dakota.
