Just 8% of doses set aside for nursing-home residents have been distributed

Across the country, efficiency in distributing the vaccine varies wildly.

The states that have administered their allotments at the highest rate include South Dakota, Connecticut and Montana – though no state has delivered more than half of the distributed doses into arms yet, according to a Bloomberg analysis of CDC data.

West Virginia has vaccinated the highest percentage of its population, with 2.18 percent of all state residents having received the first jab so far.

However, even West Virginia could be doing far better, as the state has so far administered only 38 percent of the doses that it has available.

Meanwhile, the worst-performing states for vaccine administration are Kansas, Georgia and Arizona, none of which have administered even 17 percent of the doses that they have received so far.
