Abstract
Introduction Monovalent COVID-19 boosters lower the risk of COVID-19 disease, infection, hospitalization, and death. This study examined associations between exposure to a booster public education campaign (the booster campaign) and the increases in booster uptake and reduced length of time until booster uptake among U.S. adults. Methods Data included a national survey panel of U.S. adults and booster campaign paid media (i.e., digital impressions and TV gross rating points) from September 2021 to May 2022. Multilevel logistic regression models examined the association between exposure to the booster campaign and the likelihood of booster uptake. A Cox proportional hazard model evaluated the association between the booster campaign and booster uptake timing. Interaction terms between the booster campaign media variables and first-dose COVID-19 vaccine date examined differential effects of the booster campaign based on when individuals received their first dose. Results Interactions between first-dose vaccination date and the booster campaign were statistically significant for cumulative digital impressions (ß=4.75e-08; 95% CIs=5.93e-09, 8.90e-08) and TV gross rating points (ß = 4.62e-05; 95% CIs=5.09e-06, 8.73e-05), suggesting that booster uptake was strongest among those who received their first-dose COVID-19 vaccine later. Booster campaign cumulative digital impressions and TV gross rating points were associated with accelerated booster uptake among those with later first-dose vaccination dates (digital: ß=9.98e-08; 95% CIs=2.70e-08, 1.73e-07; TV: ß=0.0001; 95% CIs=2.80e-05, 0.0002), relative to those with earlier first-dose vaccination dates. Conclusions The booster campaign may have increased monovalent booster uptake and reduced how long individuals waited until getting their booster. Public education campaigns show promise in stemming the tide of pandemic fatigue and increasing booster confidence.

Vaccine 2023; 41:7560-7572. [PMID: 37977939 DOI: 10.1016/j.vaccine.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 10/05/2023] [Accepted: 11/01/2023] [Indexed: 11/19/2023]
Abstract
INTRODUCTION It is increasingly recognized that regular boosters will be necessary for the continued management of the COVID-19 pandemic. While vaccine hesitancy in the context of the initial COVID-19 vaccinations has been extensively studied, less is known about hesitancy around boosters in the post-pandemic era, where the immediate threat of COVID-19 has diminished. METHODS Using 5,584 survey responses from people who had received at least one COVID-19 vaccine dose based on a four-round survey between May and November 2022, we examined various factors that affect booster vaccine uptake and the willingness to take an additional shot. Ordinary least squares regressions were conducted to confirm the statistical significance of the findings. RESULTS Nearly 99% of vaccinated respondents reported having had two COVID-19 vaccine doses, while 69% of respondents reported having received a booster shot (three or more vaccine doses) and 48% reported being willing to get another shot. Booster uptake was strongly increased along with the degree of trust in the Korean Disease Control Agency (KDCA) and was also significantly associated with older age, gender, political propensity, and household income-level. When examining willingness to get an additional shot, the predictors were similar to booster vaccine uptake. However, the effect of trust in the KDCA became more salient. CONCLUSION The factors associated with booster uptake and willingness to continue to boost are similar to those associated with initial vaccine acceptance in the ROK, namely trust in the public health authority and older age. Despite high initial uptake in the ROK, convincing the public of the continued necessity of routine immunization against COVID-19 may pose challenges in the post-pandemic era.

Hao F. Biden's approval, record inflation, economic recovery, COVID-19 mortality, and vaccination rate among Americans-A longitudinal study of state-level data from April 2021 to January 2022. Prev Med Rep 2023; 36:102454. [PMID: 37869537 PMCID: PMC10589899 DOI: 10.1016/j.pmedr.2023.102454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 09/29/2023] [Accepted: 10/01/2023] [Indexed: 10/24/2023] Open
Abstract
The COVID-19 pandemic has brought an unprecedented impact on Americans for over three years. One effective strategy to mitigate the pandemic's damage lies in the vaccine. This study aims to investigate the effects of state-level predictors that vary month-by-month on changes in vaccination rates. Panel data of state-level indicators are built for all 50 states from April 2021 to January 2022. The dependent variable is the monthly increase in vaccination rate, and the independent variables include measures of Biden's approval, inflation, economic recovery, and COVID-19 mortality for each month of this study period. Fixed-effects regression is adopted for longitudinal statistical estimation. Findings show that over time Biden's approval and COVID-19 death are positively associated with the growth in the vaccination rate, while inflation and economic recovery are negatively associated with the vaccination rate. Significant interactions are identified among these predictors. The findings from analyzing panel indicators at the state level complement the current literature dominated by examining cross-sectional data and provide public health officials with fresh insights to promote the vaccine rollout.

Abstract
OBJECTIVE This study aimed to investigate factors influencing the uptake of first and second COVID-19 booster vaccines among adults in Belgium, particularly age, sex, region of residence and laboratory confirmed COVID-19 infection history. RESULTS A binomial regression model was used with having received the first or second booster as outcome and age, sex, region of residence and infection history as fixed variables. Among adults, there was generally a higher uptake to receive the first booster among older age groups compared to younger ones. Females, individuals residing in Flanders and those with no previous COVID-19 infection were more likely to receive the first booster. For the second booster, the same age trend was seen as for the first booster. Males, individuals residing in Flanders and those who tested positive for COVID-19 once after first booster were more likely to receive the second booster. Individuals with multiple positive COVID-19 tests before and after primary course or first booster were less likely to receive the subsequent booster dose compared to COVID-naïve individuals. This information could be used to guide future vaccination campaigns during a pandemic and can provide valuable insights into booster uptake patterns.

Abstract
The COVID-19 pandemic has posed an unprecedented impact on Americans for over three years. To control the damage, a booster shot becomes increasingly necessary because the efficacy of the initial vaccine is waning and new variants of the virus are emerging. This study aims to understand factors at both individual and state levels that influence one's decision to take the monovalent booster. We merged data from a national survey administered in the Spring of 2022 with state-level indicators of the political climate, income inequality, and public health conditions. Multilevel logistic regression is adopted for statistical estimation. Findings show contrasting effects of the social network. More vaccinated people in one's network promote booster uptake, while more family members and close friends who contracted the virus in one's network inhibit booster uptake. In addition, residents of states with more votes for the Democratic candidate in the 2020 general election are more likely to take the booster. Meanwhile, residents from states with high income inequality are less likely to become boosted. This study identified multilevel determinants of the individual decision to receive the monovalent COVID-19 booster. The results imply the need to leverage the social network, weaken partisanship salience, and reduce income inequality to encourage booster uptake.

Abstract
The pandemic caused by SARS-CoV-2 (COVID-19) has impacted the world for close to three years and led to substantial costs to public well-being. To mitigate the pandemic's damage, the most effective approach lies in the vaccine. This study aims to investigate multilevel predictors of the public decision to become fully vaccinated against COVID-19. Data from a cross-national survey on representative samples are merged with country-level indicators. Multilevel logistic regression models are estimated on populations from 15 countries. Findings show that people who agree the government handles the pandemic well, believe the health officials would provide an effective vaccine, perceive the virus's danger, and are older are more likely to get fully vaccinated than their counterparts. Meanwhile, the national case rate and vaccination rate also affect one's decision to become fully vaccinated. Furthermore, there are significant cross-level interactions as people are more inclined to become fully vaccinated if they agree with the government's performance, perceive the virus's danger, and also reside in countries with higher case and vaccination rates. This study shows cross-national evidence regarding multilevel determinants of public vaccine uptake. Knowing the profiles among populations who have become fully vaccinated or not helps public health experts leverage factors and maximize vaccination.

COVID-19-Related Burnout and Intention of Fully Vaccinated Individuals to Get a Booster Dose: The Mediating Role of Resilience. Vaccines (Basel) 2022; 11:vaccines11010062. [PMID: 36679907 PMCID: PMC9860670 DOI: 10.3390/vaccines11010062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 12/23/2022] [Accepted: 12/24/2022] [Indexed: 12/29/2022] Open
Abstract
Because an annual COVID-19 booster vaccine appears to be required to control the pandemic, identifying the factors that influence individuals' decision to receive a booster dose is critical. Thus, our goal was to quantify the influence of COVID-19-related burnout on vaccination intention and to investigate the role of resilience in mediating the link between burnout and intention. We conducted a cross-sectional study with a convenience sample during October 2022. We used the COVID-19 burnout scale and the Brief Resilience Scale. The study sample included 1256 people who had received their primary COVID-19 vaccination. Among the participants, 34.1% reported being very likely to be vaccinated with a booster dose. COVID-19-related burnout was found to be inversely connected with vaccination intention. Moreover, our results suggested that resilience not only had a positive direct effect on vaccination intention but also mediated the relationship between burnout and vaccination intention. Although our study had limitations, such as a convenience sample and information bias, we demonstrate the critical role of resilience in reducing the impact of COVID-19-related burnout on the vaccination intention. Policymakers should develop and implement initiatives to address the issues of COVID-19-related burnout and enhance booster adoption by strengthening psychosocial resources such as resilience.
