Vaccination data in the U.S.

Here are the major data sources for vaccination data in the United States. We’ve included government sources, news publications, and independent dashboards.

The page is split into two tables: national sources and state sources. Click on a row to see detailed annotations on that source.

This resource will be updated every other week. The most recent update was November 28, 2021. For more on why we switched from weekly to biweekly updates, see this post.

  • Cash incentives for vaccination have little impact
    While politicians at all levels have praised cash incentives, research has shown that this strategy has little impact on actually convincing Americans to get vaccinated. A recent investigation I worked on (at the Documenting COVID-19 project and the Missouri Independent) provides new evidence for this trend: the state of Missouri allocated $11 million for gift cards that residents could get upon receiving their first or second vaccine dose, but the vast majority of local health departments opted not to participate in the program—and a very small number of gift cards have been distributed thus far.
  • Vaccines aren’t enough: What Biden can do about Omicron
    This past Monday, President Biden said in a speech, “We’re throwing everything we can at this virus, tracking it from every angle.” Which I, personally, found laughable. The U.S.’s anti-COVID strategy basically revolves around vaccines, and it’s not sufficient for stopping new surges.
  • Omicron variant: What we know, what we don’t, and why not to panic (yet)
    On Thanksgiving, my Twitter feed was dominated not by food photos, but by news of a novel coronavirus variant identified in South Africa earlier this week. While the variant—now called Omicron, or B.1.1.529—likely didn’t originate in South Africa, data from the country’s comprehensive surveillance system provided enough evidence to suggest that this variant could be more contagious than Delta, as well as potentially more able to evade human immune systems.
  • COVID source callout: CDC’s breakthrough case data
    The CDC has not updated its breakthrough case data since September. A full two months ago.
  • Boosters for all adults: Why eligibility expanded, and what it means for you
    On Friday morning, the FDA authorized booster shots of Pfizer’s and Moderna’s COVID-19 vaccines for all adults in the U.S., six months after their first two doses. The CDC’s vaccine advisory committee voted to support this expanded booster eligibility that afternoon, and CDC leadership signed off on it a few hours later.
