Explore Vaccination Progress by U.S. State


This table lays out the key metrics for understanding vaccination progress by U.S. state: doses administered, people fully vaccinated, and percentage of people fully vaccinated by population. The website relies upon publicly available data from multiple sources. Discrepancies may result from various issues, such as the frequency of updating compared with other sources.

Doses administered is the cumulative total of doses given. This includes first and second dose for vaccines that require two doses.

People fully vaccinated is the number of people who have received the required number of shots to achieve the highest immunity a particular vaccine offers. In the case of MRNA vaccines from Pfizer/BioNTech and Moderna, this means two doses. Other vaccines that will become available in the future may only require one dose before full immunity.

Percentage of people fully vaccinated per population helps us understand how close a particular state is to achieving a level of immunity that would slow or stop transmission of the virus. This data, when taken into consideration along with percentage of positive cases per population, gives us a better sense of overall immunity by state.
