Reminders, but not monetary incentives, increase COVID-19 booster uptake.

ABSTRACT: Despite substantially decreasing the risk of hospitalization and death from COVID-19, COVID-19 booster vaccination rates remain low around the world. A key question for public health agencies is how to increase booster vaccination rates, particularly among high-risk groups. We conducted a large preregistered randomized controlled trial (with 57,893 study subjects) in a county health system in northern California to test the impact of personal reminder messages and small financial incentives of $25 on booster vaccination rates. We found that reminders increased booster vaccination rates within 2 wk by 0.86 percentage points (P = 0.000) or nearly 33% off the control mean of 2.65%. Monetary incentives had no additional impact on vaccination rates. The results highlight the potential of low-cost targeted messages, but not small financial incentives, to increase booster vaccination rates.

Project description:ObjectiveDisparities in COVID-19 vaccine and booster uptake persist. This study aimed to obtain perspectives from community and physician stakeholders on COVID-19 vaccine and booster hesitancy and strategies to promote vaccine uptake among Black individuals with rheumatic and musculoskeletal conditions.MethodsWe invited community leaders and physicians in greater Boston and Chicago to participate in semi-structured interviews using a moderator guide developed a priori. Participants were queried about how to best address vaccine hesitancy, strategies to target high-risk populations, and factors to identify future community leaders. Interviews were audio recorded, transcribed verbatim, and analyzed thematically using Dedoose.ResultsA total of 8 physicians and 12 community leaders participated in this study between November 2021 and October 2022. Qualitative analyses revealed misinformation/mixed messaging and mistrust, with subthemes including conspiracy theories, concerns regarding vaccine development and function, racism and historical injustices, and general mistrust of health care systems as the top cited reasons for COVID-19 vaccine hesitancy. Participants also shared demographic-specific differences, such as race, ethnicity, age, and gender that influenced the identified themes, with emphasis on COVID-19 vaccine access and apathy. Strategies for community-based vaccine-related information dissemination included personal storytelling with an iterative and empathetic approach, while recognizing the importance of protecting community leader well-being.ConclusionTo increase vaccine uptake among Black individuals with rheumatic conditions, strategies should acknowledge and respond to racial/ethnic and socioeconomic injustices that engender vaccine hesitancy. Messaging should be compassionate, individually tailored, and recognize heterogeneity in experiences and opinions. Results from these analyses will inform a planned community-based intervention in Boston and Chicago.

Project description:ObjectiveEvidence shows that booster shots offer strong protection against the Omicron variant of COVID-19. However, we know little about why individuals would receive a booster compared to the initial decision to vaccinate. We investigate and assess the factors that affect individuals' reported willingness to receive the COVID-19 vaccine booster. This information can aid in tailoring public health messaging to communicate attributes that are associated with individuals' attitudes toward the COVID-19 booster.RationaleExisting research provides little insight into whether the same factors that affect Americans' likelihood of accepting initial vaccination against COVID-19 also affect booster uptake. Our experiment also examines the influence of contextual information about a novel variant on willingness to receive a booster.MethodsWe administered a conjoint experiment (N = 2740 trials) in a survey of fully vaccinated US adults that had not yet received a COVID-19 booster (N = 548) to assess the impact of varied vaccine attributes on willingness to receive a booster.ResultsThe most important factors associated with higher willingness to receive a booster were efficacy, manufacturer, and the size of a financial incentive. Protection duration and protection against future variants vs. only current variants had modest influence. A contextual prime reporting that some public health experts believe the Omicron variant is more contagious, but less lethal than those previously seen, significantly increased favorability toward boosters. This provides potential motivation and guidance for vaccination campaigns to emphasize these variant-specific traits.ConclusionWith several vaccines with varying degrees of efficacy available to consumers, emphasizing boosters with a high efficacy would likely improve attitudes toward boosters. Financial incentives and predispositions toward manufacturers also matter. Concerns about more contagious variants may spur uptake, even if such variants are less lethal.
