It's been a little over a year since COVID-19 hit US soil. Now, we're witnessing the biggest vaccination campaign in history.

Since vaccine distribution began in the US in December, 66.5 million doses have been given. In the last week, an average of 1.3 million doses per day were administered. More Americans have now received at least one dose than have tested positive for the virus since the pandemic began. Across the country, 20 doses have been administered for every 100 people. 75% of the shots delivered to states have been administered.

At the time of writing, Alaska has vaccinated the highest percentage of its state population. The first dose of the vaccine has been administered to 21.1% of Alaskan residents. Still, most of America is unvaccinated.

Currently, Puerto Rico has administered the first dose to the lowest percentage of its population out of all 50 states. 10.1% of its residents have been given the first dose. Utah and Tennessee are moving at the second and third slowest paces, at 11.1% and 11.2%, respectively.

Press the play button on the chart below to see how the stats change over time. 

Out of the eight slowest states, five of them are located in the South. This is a shift from late January, when California, Nevada, Wisconsin, and Illinois were among the states with the most lag. 

On February 24, the Food and Drug Administration shared new analyses proving the one-shot coronavirus vaccine made by Johnson & Johnson provides strong protection against COVID-19. The vaccine had a 72% overall efficacy rate in the US and 64% in South Africa, where a highly contagious variant emerged in the fall and is now driving most cases. The vaccine also showed 86% efficacy against severe forms of COVID-19 in the US, and 82% against severe disease in South Africa, meaning that a vaccinated person has a much lower risk of being hospitalized or dying from the virus. The FDA could authorize the vaccine as early as February 27, depending on a vote of its vaccine advisory panel.

On February 11, President Biden announced the federal government will purchase 600 million vaccine doses from Pfizer and Moderna to be delivered by the summer. The federal government also announced that it is using the Defense Production Act to address other issues like limited supplies of syringes or protective gear.

In late January, the Biden administration promised to provide states with  vaccine supply projections and updates at least three weeks ahead of time, an effort to increase the number of vaccinators and introduce thousands of new government-supported vaccination sites.

About the Data:

Thinknum tracks companies using the information they post online, jobs, social and web traffic, product sales, and app ratings, and creates data sets that measure factors like hiring, revenue, and foot traffic. Data sets may not be fully comprehensive (they only account for what is available on the web), but they can be used to gauge performance factors like staffing and sales.
