The race to get people vaccinated against Covid-19 is well underway and the United States has administered 5 million doses since it started its rollout on December 14, equating to 1.5 doses per 100 of its inhabitants. That falls considerably short of the 20 million dose goal the CDC states officials set for the end of December, however. Last Thursday, they said that 17 million doses were distributed to states and they acknowledged that the pace of the rollout has proven slow, though they could not explain why. What is certain is that some states have managed to get their doses administered much faster than others, as can be seen on this map which utilizes data from Bloomberg.
Every state was granted a vaccine allocation roughly proportional to its population. Bloomberg's data shows that South Dakota and West Virginia have administered the most doses per capita, with both seeing rates higher than 3 jabs per 100 of their inhabitants up to January 06, 2021. Currently, Georgia, Alabama, Mississippi and Kansas have proven the states where the effort is slowest and all of them have a current vaccination rate of less than one dose per 100 inhabitants.
