Vaccine hesitancy (VH) is considered a top-10 global health threat. The concept of VH has been described and applied inconsistently. This systematic review aims to clarify VH by analysing how it is operationalized. We searched PubMed, Embase and PsycINFO databases on 14 January 2022. We selected 422 studies containing operationalizations of VH for inclusion. One limitation is that studies of lower quality were not excluded. Our qualitative analysis reveals that VH is conceptualized as involving (1) cognitions or affect, (2) behaviour and (3) decision making. A wide variety of methods have been used to measure VH. Our findings indicate the varied and confusing use of the term VH, leading to an impracticable concept. We propose that VH should be defined as a state of indecisiveness regarding a vaccination decision.

A systematic literature review to clarify the concept of vaccine hesitancy.

To contain the COVID‐19 pandemic, higher vaccination rates are essential. However, as vaccine hesitancy is a reality, it is important to understand what drives health professionals to refuse getting vaccinated against COVID‐19, who have been in the frontline of this pandemic since its beginning and may be key actors to improve vaccine coverage among their patients.

What determines health professionals’ COVID‐19 vaccine hesitancy? A nationwide study

To investigate Covid-19 vaccine hesitancy among Iraqi healthcare workers-HCWs.Cross-sectional survey.In February 2021, an anonymous questionnaire on the willingness of receiving Covid-19 vaccination was submitted to a sample of HWCs in the Dohuk Governorate, Iraqi Kurdistan Region. Overall, 1704 questionnaires were analysed by means of univariate and multivariate statistics.The sample included 978 males and 726 females (Mean age: 36.9 ± 10.1), working in Primary Health Centres (65.8%) or in Public Hospitals (34.2%). Professions ranged from being physician/paramedics (39.3%) to administrative/laboratory staff (31.7%); 17.0% had attended up to secondary school, the rest had a higher education. Considering health conditions, 1.8% reported a poor health status and 11.5% a chronic disease.Overall, 475 people (27.9%) reported Covid-19 vaccine hesitancy, with fear of side-effects (41.4%) and lack of confidence in using the vaccine (23.5%) being the most common perceived barriers. Midwifes (61.1%) and assistant nurses (45.5%) were the most hesitant; physicians the less (12.3%). According to a binary logistic model, holding lower educational level (adjOR = 2.158; 95% CI:1.654-2.815), being female (adjOR = 1.622; 95% CI:1.289-2.040), having pre-existing chronic disease (adjOR = 1.954; 95% CI:1.280-2.983), and self-perceiving a poor health status (adjOR = 3.673; 95% CI:1.610-8.379) were independent predictors of higher odds of hesitancy.Covid-19 vaccine hesitancy among HCWs represents an important public health concern, since they play a paramount role for a successful vaccination campaign within the community. Our results show the need in Iraq to implement educational interventions for strengthening the confidence of HWCs towards the Covid-19 vaccine, therefore positively influencing the general public's attitude.

COVID-19 vaccine hesitancy and intent in California registered nurses

Vaccinations of healthcare workers (HCWs) aim to directly protect them from occupational diseases, and indirectly protect their patients and communities. However, studies increasingly highlight that HCWs can be vaccine hesitant. This review aims to analyze HCWs’ and public health professionals’ sentiments toward COVID-19 (Coronavirus Disease 2019) vaccination and determinants across different countries. A search strategy was conducted in PubMed using keywords such as “COVID-19”, “sentiment/acceptance”, “healthcare workers”, “vaccine hesitancy”, and “influenza”. A total of 56 articles were selected for in-depth analyses. The highest COVID-19 vaccination uptake was found in an Italian study (98.9%), and the lowest in Cyprus (30%). Older age, male gender, the medical profession, higher education level, presence of comorbidities, and previous influenza vaccination were associated with vaccine acceptance. Factors for low acceptance were perceived side effects of the vaccine, perceived lack of effectiveness and efficacy, and lack of information and knowledge. Factors for acceptance were knowledge, confidence in the vaccine, government, and health authorities, and increased perception of fear and susceptibility. All studies focused on healthcare providers; no studies focusing on public health professionals’ sentiments could be found, indicating a gap in research that needs to be addressed. Interventions must be implemented with vaccination campaigns to improve COVID-19 vaccine acceptance.

Determinants of Acceptance of COVID-19 Vaccination in Healthcare and Public Health Professionals: A Review

Correlates of COVID-19 Vaccine Acceptance, Hesitancy and Refusal among Employees of a Safety Net California County Health System with an Early and Aggressive Vaccination Program: Results from a Cross-Sectional Survey.

Information on vaccine acceptance among healthcare workers is needed as health professionals provide front line care to COVID-19 patients. We developed and implemented an anonymous internet-based cross-sectional survey with direct solicitation among employees of a safety net health system. Items queried demographic and health-related characteristics, experience with and knowledge of COVID-19, and determinants of decisions to vaccinate. COVID-19 vaccine acceptance groups (acceptors, hesitant, refusers) were defined; an adapted version of the WHO vaccine hesitancy scale was included. The survey demonstrated good reliability (Cronbachs alpha = 0.92 for vaccine hesitancy scale; 0.93 for determinants). General linear and logistic regression methods examined factors which were univariately associated with vaccine hesitancy and vaccine acceptance, respectively. Multivariable models were constructed with stepwise model-building procedures. Race/ethnicity, marital status, job classification, immunocompromised status, flu vaccination and childhood vaccination opinions independently predicted hesitancy scale scores. Gender, education, job classification and BMI independently predicted acceptance, hesitancy and refusal groups. Among hesitant employees, uncertainty was reflected in reports of motivating factors influencing their indecision. Despite a strong employee-support environment and job protection, respondents reported physical and mental health effects. Appreciation of varied reasons for refusing vaccination should lead to culturally sensitive interventions to increase vaccination rates in healthcare workers.
