Results of multivariate regression models showing association between annual influenza vaccination and types of cardiovascular disease among US adults, Behavioral Risk Factor Surveillance System, January 2011–December 2020. Models were adjusted for reported sociodemographic characteristics, health care characteristics, and cardiovascular disease risk factors. Error bars indicate 95% CIs. Except for heart attack/myocardial infarction, odds are significant at P < .05 by 2-sided z test. Abbreviations: CHD, coronary heart disease; CVD, cardiovascular disease; MI, myocardial infarction.

| Yes | 1.18 (1.15–1.22) |
| No | 1 [Reference] |
| Heart attack or myocardial infarction | |
