• Weekly COVID-19 Vaccination Coverage and Comparison among adults 18 Years and Older by Selected Demographics and by Season

• Weekly estimates of COVID-19 vaccination coverage and intent for vaccination among adults are calculated using data from the National Immunization Surveys (NIS)-Fall Respiratory Virus Module (NIS-FRVM) (https://www.cdc.gov/nis/about/index.html).

• The NIS–FRVM is an ongoing random-digit-dial cellular telephone survey of households with adults 18 years and older. All estimates are based upon self-reported receipt of vaccination and month of that vaccination.

• Weekly comparisons to previous season should take into account differences between seasons in vaccine availability dates. 2023–24 COVID-19 vaccines were first available mid-September 2023, and 2024–25 and 2025–26 COVID-19 vaccines were first available at the end of August 2024 and 2025, respectively.

• The NIS-FRVM data posted on the dashboard below are currently a few days behind the data that are posted on the Respiratory Illnesses Data Channel (https://www.cdc.gov/respiratory-viruses/data/index.html). This lag is due to the time it takes to review data by geographic and sociodemographic characteristics and summarize the findings.
