Rates of COVID-19 Cases and Deaths by Vaccination Status

To monitor rates of COVID-19 cases and deaths by vaccination status, data are reported from jurisdictions that link case surveillance data to immunization registries to identify the vaccination status of people who test positive for COVID-19. The participating jurisdictions represent over half of the U.S. population and all regions of the country. This page displays an interactive figure showing overall weekly rates of COVID-19 cases and deaths among fully vaccinated and unvaccinated people ages 12 years and older, according to COVID-19 positive specimen collection date. Another graph displays rates of COVID-19 cases and deaths among fully vaccinated people with and without an additional or booster dose and unvaccinated people ages 18 years and older. Rates by age group and primary series vaccine type are also shown for both graphs. Overall rates are standardized by age. Rates are not adjusted for time since vaccination, underlying conditions, or most demographic factors, aside from age. Monitoring COVID-19 rates by vaccination status can indicate changes in vaccine effectiveness that can be confirmed through robust, controlled studies.

These data will be updated monthly.

  • People who were unvaccinated had a greater risk of testing positive for COVID-19 and a greater risk of dying from COVID-19 than people who were fully vaccinated (see below for the most recent rates).
  • Unvaccinated people in all age groups had higher case and death rates than fully vaccinated people in the same age groups.
  • Case and death rates for people fully vaccinated with any of the three vaccine types (Moderna, Pfizer-BioNTech, Johnson & Johnson’s Janssen) were much lower than for unvaccinated people.
  • People who were fully vaccinated with an additional or booster dose had lower case rates compared with those without an additional or booster dose. Both of these groups had much lower risk of testing positive for COVID-19 and a lower risk of dying from COVID-19 compared with people who were unvaccinated.
    • People ages 65 and older had a larger overall benefit from receiving an additional or booster dose, compared with younger age groups.
