Eleven states publicly report data on current or cumulative COVID-19 hospitalized based on vaccination status.
In December, the monthly rate of COVID-19-associated hospitalizations was 16 times higher for unvaccinated Americans 18 years and older, compared to fully vaccinated Americans, according to CDC data.
Below is a breakdown of hospitalizations by vaccination status based on data from each state's official COVID-19 dashboard. Discrepancies exist in terms of how each state reports this data. States either sort hospitalizations by vaccinated versus unvaccinated, or vaccinated versus partially vaccinated. Some only offer percentages or rates, instead of hospitalization totals.
Note: Iowa and Louisiana only provide the percentage of unvaccinated or partially vaccinated hospitalizations; Becker's calculated the percentage of vaccinated hospitalizations.
