[PMID: 38081754 DOI: 10.1016/j.vaccine.2023.11.051] [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: 08/31/2023] [Revised: 11/07/2023] [Accepted: 11/25/2023] [Indexed: 01/01/2024]
Abstract
BACKGROUND Vaccination is crucial for prevention of infectious diseases, and identification of the impact of vaccine hesitancy on vaccination programs is crucial for early intervention and formulation of policies to alleviate vaccine hesitancy. The aim of this systematic review was to explore the relationship between vaccine hesitancy and negative vaccination behavior globally. METHODS We searched for observational studies in various databases. We conducted a meta-analysis using pooled odds ratios (OR) and 95 % confidence intervals (CI), performed meta regression and subgroup analysis to explore the role factors such as location and individual characteristics on the association between vaccine hesitancy and vaccination behavior. RESULTS A total of 46 articles were included in systematic analysis and 34 articles were included in the meta-analysis. The systematic analysis comprised 162,601 samples, whereas the meta-analysis included 147,554 samples. The meta-analysis showed that a higher rate of vaccine hesitancy was associated with an increased likelihood of adverse vaccination behaviors (all adverse behaviors: OR = 1.50, 95 % CI, 1.33-1.70, P < 0.001; unvaccinated: OR = 1.48, 95 % CI, 1.29-1.70, P < 0.001; vaccine delay: OR = 2.61, 95 % CI, 1.97-3.44, P < 0.001). The meta-regression results indicated that the heterogeneity observed was mainly from sample selection methods, age of vaccinees and the health status of participants. The results showed that parents of minor vaccinees or without high-risk health status had a higher association between vaccine hesitancy and vaccine uptake compared with populations exposed to higher health risks or adult vaccinees. CONCLUSION The findings provide evidence on the association between vaccine hesitancy and adverse vaccination behaviors. The results showed that these population-specific factors should be considered in future research, and during formulation of interventions and implementation of policies to improve vaccination uptake.

Abstract
COVID-19 vaccine uptake in the United States has proved challenging. A deeper characterization extending beyond demographics and political ideologies of those hesitating or resisting is needed to guide ongoing conversations. This study examined associations between US adults' vaccination intentions and mental health history, experience of the COVID-19 pandemic, and mental health outcomes. An online population-based cross-sectional survey was administered nationwide during January 4-7, 2021. Participants were questioned about past and current mental health, and completed the Patient Health Questionnaire 8 (PHQ-8), Generalized Anxiety Disorder 7-item (GAD-7), and Posttraumatic Diagnostic Scale (PDS)-5 (to capture symptoms of depression, anxiety, and traumatic stress, respectively). Experience of the pandemic included cumulative county-level COVID case and death rates, self-reported COVID-19 testing/exposure/diagnosis, and self-reported impact on routines, resources, and relationships. Of 936 respondents, 66% intended to be vaccinated, 14.7% responded "maybe," and 19.6% "no." Past diagnosis of obsessive compulsive disorder, less impact on routines or social supports, not having been screened or tested for COVID-19, not knowing someone who tested positive, and not self-isolating were associated with less intention to vaccinate. After controlling for demographic and pandemic experience factors, symptoms of traumatic stress, but not other mental health outcomes, were associated with less intention to vaccinate. The apparent contradiction between less negative impact of the pandemic and symptoms of traumatic stress being associated with less intention to be vaccinated indicates the complex nature of barriers to vaccine uptake. Results from this study contribute to the evidence base needed to improve ongoing and future communications about, and strategies to increase uptake of, vaccination.

Vaccine 2023; 41:1567-1572. [PMID: 36725432 PMCID: PMC9868364 DOI: 10.1016/j.vaccine.2023.01.044] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 01/18/2023] [Accepted: 01/19/2023] [Indexed: 01/24/2023]
Abstract
BACKGROUND The public's willingness to get vaccinated continues to be a source of concern. In this study we assessed the psychometric properties of the COVID-19 vaccine hesitancy scale (C19-VHS) as well as the association between the scale and self-reported past COVID-19 vaccination, approximately two weeks after the national vaccine distribution plan was launched in Israel. METHODS Participants were recruited via an online survey distributed through social media platforms and mailing lists. A total of 650 individuals completed the C19-VHS, the general vaccine hesitancy scale, and the fear of COVID-19 scale, and reported on demographic and pandemic-related characteristics. Principal component and Cronbach's alpha analyses were performed to assess the factor structure and reliability of the scale. Logistic regressions were employed to assess the scale's convergent and discriminative validity. RESULTS Two factors pertaining to "lack of confidence" (Factor 1) and "risk perception" (Factor 2) emerged. Cronbach's alpha indicated good reliability of Factor 1 (0.93), with lower reliability of Factor 2 (0.72). Younger age was associated with higher risk perception, with women showing less confidence and perceiving greater risks. Lower hesitancy significantly predicted actual COVID-19 vaccine uptake after adjusting for demographic and pandemic-related factors (OR = 1.16, 95%CI 1.11-1.21, p <.001). Older age, being a woman, and receiving the flu vaccine in the past year were also predictive of COVID-19 vaccine uptake. DISCUSSION The C19-VHS measure shows robust psychometric properties and is associated with actual vaccine uptake. Future studies assessing COVID-19 vaccination attitudes may utilize this scale to assess current COVID-19 vaccine hesitancy in different contexts and cultures.

Infection preventionists' experiences during the second year of the COVID-19 pandemic: Findings from focus groups conducted with association for professionals in infection control & epidemiology (APIC) members. Am J Infect Control 2023; 51:121-128. [PMID: 36463974 PMCID: PMC9714080 DOI: 10.1016/j.ajic.2022.11.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 11/23/2022] [Accepted: 11/28/2022] [Indexed: 12/05/2022]
Abstract
INTRODUCTION COVID-19 epidemiology changed dramatically in spring 2021 when vaccine became widely available and the Delta variant emerged. There was a need to identify current infection prevention challenges due to changing pandemic epidemiology. METHODS Six focus groups were conducted via Zoom with APIC members in November and December, 2021 to elicit infection preventionists' (IP) experiences with the COVID-19 pandemic after the Delta variant had emerged. Each focus group was audio recorded then transcribed verbatim. Content analysis was used to identify major themes. RESULTS In total, 90 IPs participated (average of 15 IPs per focus group). Participating IPs described multiple issues they have faced during the second year of the COVID-19 pandemic after the Delta variant emerged, including continuing challenges with personal protective equipment, changes in pandemic restrictions that caused confusion and pushback, the hope when vaccine first became available and then despair when there was more vaccine breakthrough than anticipated, staffing and medical supply shortages, overwhelming workloads, and anger towards health care personnel and IPs. However, IPs felt more valued by leadership, and reported greater internal collaboration and external coordination of care. CONCLUSIONS The second year of the pandemic brought ongoing and new challenges for IPs, but also better coordination of care. Strategic initiatives are needed to address the identified challenges, such as how to prioritize tasks when IPs are overwhelmed.
