Vaccine hesitancy, especially in the setting of an ongoing COVID-19 pandemic and upcoming flu season, may pose a significant burden on US healthcare systems. The objective of this study was to evaluate the intentions of US adults to receive the influenza vaccine this flu season (2020–2021). A cross-sectional, population-based survey study of US adults age 18 years and older was distributed in early September 2020. The primary outcome was the intention to receive the flu vaccine assessed with a survey instrument based on the Theory of Planned Behavior. Three-hundred sixty-four adults (59.1% female, 66.5% white), completed the survey. Twenty percent of participants had already received the flu vaccine, 54.3% indicated high probability of getting the flu vaccine this flu season, and 49% would get it at a doctor’s office. Concerns regarding adverse effects from the flu vaccine was a major barrier to vaccination and family (58.1%) was the primary influencer in participants’ decision to get vaccinated. Participants who indicated that getting the vaccine was beneficial to them and that their doctor thinks they should get the flu vaccine were significantly more likely to have the intent of getting vaccinated. Approximately half of US adults believed that the flu vaccine was beneficial to them and indicated intent to receive the vaccine this flu season. Doctors can help educate patients regarding the limited adverse effects of flu vaccines, and include patients and their families in vaccination discussions – because families are influential in the decision-making process – to increase flu vaccination uptake.
