Influences on COVID-19 booster uptake among adults intending to receive a booster: a qualitative study

Abstract

Abstract Bivalent COVID-19 vaccine boosters have been recommended for all Americans 12 years of age and older. However, uptake remains suboptimal with only 17% of the United States (US) population boosted as of May 2023. This is a critical public health challenge for mitigating the ongoing effects of COVID-19 infection. COVID-19 booster uptake is not currently well understood, and few studies in the US have explored the vaccination process for booster uptake in a ‘post-pandemic’ context. This study fills gaps in the literature through qualitative analysis of interviews with a racially/ethnically diverse sample of Arkansans who received the COVID-19 vaccine main series and expressed intent to receive a booster (n = 14), but had not yet received the COVID-19 booster at the time we recruited them. All but one did not receive the booster by the time of the interview. Participants described influences on their vaccination behavior and uptake of boosters including reduced feelings of urgency; continued concerns about the side effects; social contagion as a driver of urgency; increasing practical barriers to access and missing provider recommendations. Our findings highlight the importance of considering vaccination as an ongoing, dynamic process drawing on past/current attitudes, prior experience, perceptions of risk and urgency and practical barriers. Based on these findings, healthcare providers should continue to provide strong, consistent recommendations for COVID-19 boosters to patients, even among those with histories of vaccine uptake.
