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. In rural Alaska, remote villages lack any connection to roads or hospitals, nor do they have access to the ultra-cold freezers needed to preserve doses. Still, Alaska has remained in the lead of America's vaccination efforts.

"Those problems, however, have not thwarted the vaccine's delivery. Instead, bolstered by special shipments for Alaska Native tribes, providers have mobilized a massive effort that's delivering thousands of doses to remote parts of the state," NPR reports. "A fleet of chartered plans has airlifted vials to villages. A water taxi drove doses through choppy seas."

New Mexico follows with 19.3%. South Dakota follows with 18%. Press the play button on the chart below to see how the stats change over time. 

At least 1,000 New Mexico veterans received their COVID vaccinations on Feb 23. The drive-thru clinic comes before they begin sending the vaccine to their outpatient clinics in rural areas.

West Virginia has moved down to sixth fastest state with 16.4%, after racing neck and neck with Alaska over the last few weeks. The state has enacted a centralized state-run system after calling on the National Guard to help with logistics and organization of the vaccine. 

"Once vaccines come to the state health department, they’re shipped to five hospitals, each located in a different geographic region of the state," according to the Washington Post. "These hospitals then serve as a hub for distributing the vaccines to community health centers, clinics, pharmacies, doctor officers and other hospitals. The state tracks the movement of all vaccines with a central registration system."

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.
