As the nation and individual states prepare to ramp up COVID-19 vaccination rollout campaigns beyond the initial phase of prioritized recipients, understanding the challenges they face in getting vaccines to key resident demographics is important to their success in achieving population-level coronavirus immunity—also commonly known as “herd immunity.”

While states and federal organizations are slowly beginning to collect and disseminate what data they’ve been able to collect regarding COVID vaccination thus far, it is still limited. Adult flu vaccine data, however, can be used as the best available proxy in the meantime for understanding vaccination patterns across states and the nation on a larger scale.

This set of two-page infographics explores state-level estimates on flu vaccination rates for adults (age 18+) using data for all 50 states and the District of Columbia (D.C.) from the Behavioral Risk Factor Surveillance System (BRFSS) survey.

The infographics provide comparisons for individual state flu vaccine rates to the minimum COVID-19 herd immunity target (70%). Each individual state infographic also highlights vaccination rates for individual states as compared to a number of demographic categories, including age, race/ethnicity, household income level, insurance status, chronic conditions, access to care, and educational attainment.
