A qualitative meta-synthesis on how autonomy promotes vaccine rejection or delay among health care providers

Vaccine hesitancy: a structured review from a behavioral perspective (2015-2022)

Vaccine hesitancy, a complex behavioral phenomenon, poses a significant global health threat and has gained renewed attention amidst the COVID-19 pandemic. This paper scrutinized peer-reviewed literature on vaccine hesitancy published from 2015 to 2022, with a specific focus on behavioral perspectives, utilizing a Theories-Constructs-Variables-Contexts-Methods (TCVCM) framework. The study highlighted prominent theoretical approaches, abstract concepts, research variables, global contexts and academic techniques employed across a selected sample of 138 studies. The result is a consolidated overview of research and schematization of the factors influencing vaccine hesitancy and vaccination behaviors. These include individual-level, contextual, vaccine-specific, organizational, and public-policy-related dynamics. The findings corroborated the complexity of vaccine hesitancy and emphasized the difficulties of pursuing vaccine advocacy. The analysis also identified several directions for future research, and the need to conduct more contextual studies in low- and middle-income nations to bring out the cross-cultural nuances of vaccine hesitancy.

Views about vaccines and how views changed during the COVID-19 pandemic among a national sample of young gay, bisexual, and other men who have sex with men

We examined perceptions of vaccines and changes during the coronavirus disease 2019 (COVID-19) pandemic. From 2019 to 2021, a national sample of young gay, bisexual, and other men who have sex with men completed an open-ended survey item about vaccine perceptions. Analyses identified themes and polarity (negative, neutral, or positive) within responses and determined temporal changes across phases of the pandemic ("pre-pandemic," "pandemic," "initial vaccine availability," or "widespread vaccine availability"). Themes included health benefits of vaccines (53.9%), fear of shots (23.7%), COVID-19 (10.3%), vaccines being safe (5.6%), and vaccine hesitancy/misinformation (5.5%). Temporal changes existed for multiple themes (p < .05). Overall, 53.0% of responses were positive, 31.2% were negative, and 15.8% were neutral. Compared to the pre-pandemic phase, polarity was less positive for the widespread vaccine availability phase (odds ratio = 0.64, 95% confidence interval: 0.42-0.96). The findings provide insight into how vaccine perceptions change in concert with a public health emergency.

A taxonomy of anti-vaccination arguments from a systematic literature review and text modelling

The proliferation of anti-vaccination arguments is a threat to the success of many immunization programmes. Effective rebuttal of contrarian arguments requires an approach that goes beyond addressing flaws in the arguments, by also considering the attitude roots-that is, the underlying psychological attributes driving a person's belief-of opposition to vaccines. Here, through a pre-registered systematic literature review of 152 scientific articles and thematic analysis of anti-vaccination arguments, we developed a hierarchical taxonomy that relates common arguments and themes to 11 attitude roots that explain why an individual might express opposition to vaccination. We further validated our taxonomy on coronavirus disease 2019 anti-vaccination misinformation, through a combination of human coding and machine learning using natural language processing algorithms. Overall, the taxonomy serves as a theoretical framework to link expressed opposition of vaccines to their underlying psychological processes. This enables future work to develop targeted rebuttals and other interventions that address the underlying motives of anti-vaccination arguments.

Vaccine hesitancy and acceptance: an examination of predictive factors in COVID-19 vaccination in Saudi Arabia

Vaccine hesitancy is a global health issue and can be affected by several variables. We explored the predictive factors and causes of vaccine hesitancy among adults in Saudi Arabia. An online survey method with multiple regression analysis was used to identify factors predicting of vaccine hesitancy in 558 adults (46.24% women and 53.76% men). The prevalence of vaccine hesitancy is 20.6%, with higher rates among females, young people and single people. About 70% of the participants believe that vaccine hesitancy is due to concerns about the safety and efficacy of the vaccine, a lack of information about the disease and vaccine or social media. The vaccine acceptance rate is 71.3%; 17.2% are not willing to accept a COVID-19 vaccine and 11.5% are unsure. Males and married people are more accepting of the vaccine. The risk factors that predict vaccine hesitancy include age, gender, belief in conspiracy theories and psychosocial factors. Meanwhile, age, gender, belief in conspiracy theories, concerns about the safety and efficacy of the vaccine and psychosocial factors significantly predict vaccine acceptance. The high rate of vaccine hesitancy could undermine efforts to combat COVID-19. Factors predicting vaccine hesitancy can be used in interventions to address this issue during major epidemics.

Knowledge and attitudes toward vaccination among nurses and midwives in Cyprus: A cross-sectional study

PURPOSE

To assess the level of knowledge and attitudes of nurses and midwives in Cyprus toward vaccinations and provide new insights into the determinants that influence them.

METHODS

An online cross-sectional study was carried out during the period between December 08 and 28 2020. Participants included registered nurses and midwives working in public or private service provision. A self-administered questionnaire was used with questions about sociodemographic characteristics, questions assessing attitudes and beliefs toward vaccination, and participants' general vaccine knowledge.

FINDINGS

A total of 437 responders answered the survey, with 93% being nurses and 7% midwives. Around two-thirds (67.3%) of the participants had a high vaccination knowledge, while the remaining have moderate (30.7%), and low (2.1%), respectively. Most of the participants agreed that by vaccinating they protect themselves and those around them (80.5%) and that when most people are not vaccinated, epidemics can easily initiate (74%). Oppositely, many participants disagreed with vaccination and avoided it due to a fear of injections (95.4%) or the belief that it is better to get sick rather than be vaccinated (69.1%). Neutral attitudes toward vaccine-mediated side effects (43.1%) and vaccination safety (41.7%) were observed. Sociodemographic factors such as age, educational status, and work setting significantly affected the nurses' and midwives' knowledge and attitudes toward vaccination (p < 0.05).

CONCLUSIONS

The findings indicate that the overall vaccination knowledge of participants was high, however, gaps in vaccination knowledge were observed. Individuals who adopted a neutral stance toward vaccination can be prone to changes either toward positive or negative attitudes.

IMPLICATIONS FOR NURSING PRACTICE

The survey findings suggest implementing educational strategies and targeted interventions in clinical settings to enhance nurses' and midwives' vaccination knowledge and awareness.
