State-level Vaccination Coverage
[1] “RSV vaccination coverage is not shown at this time due to an issue with the availability of state-specific coverage estimates.”

These figures show national and state-level trends in vaccination coverage, representing percentage of the (age-specific) population ‘up-to-date’ for vaccination against COVID-19 or flu based on National Immunization Survey Fall Respiratory Virus Module (NIS-FRVM, previously called the Adult COVID Module or NIS-ACM) data. Data are shown for the 2025-2026 respiratory virus season, beginning October 2025, and for the previous 2024-2025 season (low-opacity, dotted lines). NIS-FRVM estimates are derived from self-report data obtained through phone surveys and may differ from estimates based on other data sources. In addition to random error associated with taking a sample, NIS-FRVM data are subject to errors resulting from incomplete sample frame, selection bias, and errors in self-reported vaccination status. Estimates are weighted to selected sociodemographic characteristics of the U.S. population to reduce possible bias from incomplete sample frame and selection bias.
