**The presence or absence of superscripted letters denotes whether that estimate was statistically significantly different at P < 0·05 from another row, and denotes which row it differed from (a, b, c, d, or e), based on pair‐wise comparison t‐test. For example, the percentage of Hispanics (a) believing the 2009 H1N1 vaccine was effective (73·5%) was statistically significantly different from the percentage of black, non‐Hispanics (b) with this belief (69·2%).
***Poverty level based on reported income and number of persons in the household and using U.S. poverty thresholds.
†Priority group for 2009 H1N1 defined as age 18–24 years, or high‐risk medical condition, health care worker, close contact with children <6 months, and pregnant women.
