(CNN)When you compare states with high vaccination rates to states that are lagging, the difference in the number of people getting Covid-19 is staggering. Over the past week, states that have fully vaccinated more than half of their residents have reported an average Covid-19 case rate that is about a third of that in states which have fully vaccinated less than half of their residents, according to a CNN analysis of data from Johns Hopkins University and the Centers for Disease Control and Prevention. Alabama, Mississippi and Arkansas are the only states to have fully vaccinated fewer than 35% of their residents. Average daily case rates in each state were among the 10 worst in the country last week. Vermont leads the nation with about 66% of its population fully vaccinated — and while case rates there increased compared to last week, the state still had the lowest case rate in the country last week, with an average of less than one new case per 100,000 people each day.
