Belief in misinformation and acceptance of COVID-19 vaccine boosters: A survey analysis.

Objective: This study examines the impact of misinformation belief on the willingness of American adults to receive ongoing COVID-19 vaccine boosters. Methods: A representative survey of 600 adults in the state of Florida was fielded in August of 2023. For this study, responses were analyzed for the 443 previously vaccinated respondents in that sample using both descriptive and inferential statistical methods. Results: Among previously vaccinated individuals, belief in misinformation remained relatively high. 49% of respondents believe that COVID-19 vaccines contain a live strain of the virus, and roughly 40% believe that vaccines can cause you to "get sick" with COVID-19. Belief in misinformation was associated with a statistically significant decrease in the likelihood of receiving ongoing vaccine boosters, ceteris paribus. Conclusion: While confidence in public health guidelines is the most compelling determinant of vaccine acceptance, misinformation continues to undermine vaccination efforts. Addressing common myths about COVID-19 vaccines may help to improve booster shot acceptance among previously vaccinated Americans. Innovation: Throughout the COVID-19 pandemic, health professionals and public health agencies have been forced to innovate in real-time, as digital platforms have fueled the spread of viral misinformation. This study aims to inform these efforts by exploring and deepening our understanding of the impact that belief in misinformation has on vaccination behaviors.

Breakthrough COVID-19 infections and perceived vaccine effectiveness.

INTRODUCTION: While SARS-CoV-2 vaccines provide significant protection against severe COVID-19 illness, breakthrough infections have sparked confusion among patients about the effectiveness of vaccination. It's unclear if (or to what extent) breakthrough infection experiences impact public perceptions of COVID-vaccine effectiveness, though the answer may have significant implications for public health communications and ongoing vaccine acceptance. METHODS: We conducted a survey of 2,500 adults in the United States (February 27 - March 9, 2023) in order to better understand the relationship between breakthrough COVID-19 infections and perceived vaccine effectiveness. Survey respondents were selected using a stratified, quota sampling approach to ensure representativeness; analysis was conducted on responses from 1,928 participants who received a COVID-19 vaccine. FINDINGS: Among those who tested positive for COVID-19 after being vaccinated, 21.18 % said that COVID-19 vaccines had been "less effective" than they initially expected, compared with 10.0 % of those who did not experience any breakthrough infections (X2 = 75.551; φ = 0.198; p ≤ 0.001). Those who experienced their own breakthrough infection were 1.37 times less likely to report perceived vaccine efficacy, while those whose family members experienced a breakthrough infection were 1.64 times less likely to report the same, ceteris paribus. The largest effect was observed among those who experienced both a personal and familial breakthrough infection. This group was almost two times less likely to describe COVID-19 vaccines as "very effective". DISCUSSION: Breakthrough infections correlated with lower overall levels of perceived vaccine effectiveness, even after accounting for demographic and political considerations. Moving forward, public officials and health professionals should work proactively to ensure that breakthrough infections are understood in the broader context of overall vaccine effectiveness.

Breakthrough infections and acceptance of COVID-19 vaccine boosters: A survey analysis.

Objective: This Short Communication explores the effect of COVID-19 breakthrough infections (defined as a COVID-19 diagnosis after vaccination) on the willingness of previously vaccinated individuals to receive ongoing vaccine boosters. Specifically, we examine unique effects for three different breakthrough infection experiences, including the participant themselves, a close member of their family, and a friend/coworker. Methods: A representative, web-based survey of 600 adults in the state of Florida was fielded in March/April of 2022. Among the respondents, 455 had been vaccinated against COVID-19. Their responses were analyzed for this study using both descriptive and inferential statistical methods. Results: Individuals who have experienced a personal breakthrough infection are two times less likely to receive annual vaccine boosters, ceteris paribus. However, there is not a statistically significant relationship between vaccine acceptance and breakthrough infections among close family members or friends/coworkers. We also found a very strong relationship between vaccine decisions and confidence in public health guidance. Conclusion: Our findings show that confidence in public health guidelines is the most compelling determinant of vaccine acceptance, but breakthrough infections also have a significant impact on individual decision making when it comes to ongoing vaccination. Going forward, public health messaging should directly account for this correlation in order to effectively maintain vaccination levels. Innovation: The COVID-19 pandemic marked a turning point in the development and deployment of mRNA vaccines. This study contributes to innovation in health communication research by examining how breakthrough infections in these vaccinated individuals impacts ongoing booster shot acceptance. The findings of this study contribute to the nascent and ongoing development of baseline research in this area.

Receptiveness of American adults to COVID-19 vaccine boosters: A survey analysis.

Objective: This Short Communication report summarizes results from a recent survey on the willingness of American adults to accept COVID-19 vaccine boosters. We seek to identify evolving hesitancies and objections to booster shots among those who previously accepted vaccination. Methods: A representative, web-based survey of 600 adults in the State of Florida was fielded, and the results are analyzed using both descriptive and inferential statistical methods. Results: The survey responses show that while booster shot hesitancy is relatively low among vaccinated Americans, nearly a third (30.4%) say that they are only somewhat likely or less to receive a vaccine booster shot. Statistical analysis shows that trust in public health guidance is the driving factor behind booster shot hesitancy, while significant differences also exist based on race and level of education. The most frequently cited objections to booster shots include concerns over the necessity of additional shots and adverse reactions to the initial vaccination. Conclusion: Objections to booster shots highlight emerging communications challenges that health professional will need to consider and address as vaccine guidance continues to evolve. Innovation: This study contributes to innovation in health communications by identifying emerging challenges and barriers in the ongoing effort to promote COVID-19 vaccination.

Vaccine Hesitancy and Exposure to Misinformation: a Survey Analysis.

INTRODUCTION: Despite the widespread availability of SARS-CoV-2 vaccines in the USA, vaccine hesitancy continues to represent a significant impediment to the attainment of herd immunity and the end of the COVID-19 pandemic. This survey analysis provides an update for clinical healthcare providers and public health officials regarding current trends in misinformation exposure, as well as common objections to COVID-19 vaccination. METHODS: We conducted a web-based survey of 600 adults in the state of Florida between June 3 and June 14, 2021. Access to the sample was purchased through an industry-leading market research provider (Prodege MR), and survey respondents were selected using a stratified, quota sampling approach to ensure representativeness. Balanced quotas were determined (by region of the state) for gender, age, race, education, and ethnicity. The survey responses were analyzed using basic descriptive statistics, as well as chi-square testing and a logit regression model. FINDINGS: High levels of misinformation exposure were observed among participants, with 73% reporting some exposure to misinformation about COVID-19 vaccines in the past 6 months. Exposure to misinformation was directly correlated with vaccine hesitancy. Among those who did not report any exposure to misinformation, 73.8% of respondents were vaccinated. That number fell to 62.9% with exposure to just one misinformation theme and 52.2% for six or more (χ2 = 11.349; φ = 0.138; p ≤ 0.05). Politicization was also found to be a major factor in vaccine hesitancy, with 73.4% of self-identified Democrats being vaccinated, compared to only 58.5% of Republicans and 56.5% of Independents (χ2 = 16.334; φ = 0.165; p ≤ 0.001). Both misinformation exposure and political affiliation were strong predictors of vaccination even after accounting for other demographic predictors. DISCUSSION: The survey results add to previous research on misinformation and vaccine hesitancy by quantifying exposure to specific misinformation themes and identifying its relationship to vaccine hesitancy. Overcoming these impediments to vaccination will require strategic and targeted messaging on the part of public health professionals, which may be aided by collaboration with political thought leaders. Understanding the volume and nature of misinformation themes the public is exposed to regarding COVID-19 vaccines may aid public health officials in targeting this vaccine messaging to more directly address reasons for vaccine hesitancy.
