KFF COVID-19 Vaccine Monitor: September 2021
Findings
Differences in estimates of the number of people vaccinated between surveys and administrative data may be due to multiple factors, including survey timing, sampling error, lags in state data reporting, and missing data on race/ethnicity.
The item asking about full FDA approval was only asked of those who were vaccinated in August or September. Results are reported based on those vaccinated since June 1 since the sample size of those vaccinated in August and September is too small for analysis.
Case rates per 100,000 and death rates per 100,000 are based on 7-day average in each U.S. county as of September 13, 2021. Data access from the New York Times.
