The effect of vaccination beliefs regarding vaccination benefits and COVID-19 fear on the number of vaccination injections

Positive vaccine beliefs linked to reduced mental stress in healthcare professionals during COVID-19: a retrospective study

Background and aim

The COVID-19 pandemic has led to a significant adverse effect on the mental health of healthcare professionals. This study aims to assess the effects of the prolonged pandemic on burnout and mood disorders and to evaluate the influence of positive vaccination beliefs on these factors at a medical center during the extended COVID-19 pandemic.

Methods

This retrospective study analyzed the results of an online questionnaire survey including burnout status and mood disorders from 2020 to 2022. The factors related to mood moderate/severe disorders and the impact of the positive vaccine belief were also explored.

Results

The initial analysis revealed that healthcare professionals continued to experience significant levels of personal and work-related burnout, along with mood disorders. However, the scores and the percentage of moderate to severe burnout gradually decreased. Notably, the percentage of individuals with moderate to severe mood disorders also gradually declined (2020: 13.4%, 2021: 12.3%, 2022: 11.1%). The number of participants who need professional interventions decreased from 56.2% in 2020 to 45.9% in 2021, and 46% in 2022. Multivariate analysis revealed a positive vaccine belief was associated with a lower risk of moderate/severe mood disorders, with odd ratios (OR) and 95% confidence intervals (95% CI) of 0.38 (0.28 - 0.52) and 0.41 (0.30 - 0.52) in the 2021 and 2022 cohorts, respectively. Further investigation revealed that age over 50 was linked to a positive vaccine belief in 2021 and 2022. Within the 2022 cohort, working as nurses was identified as the independent factor associated with a less positive belief, with the OR and 95% CI of 0.49 (0.27 - 0.90).

Conclusion

The findings of the present study suggest burnout and mood disorders are still significant during the pandemic. A positive vaccine belief may mitigate pandemic-related mental distress. Further interventions to enhance the belief combined with other supporting measures are important in a long fight against the pandemic.

Behavioural and social drivers of COVID-19 vaccination in Vietnam: a scoping review

BACKGROUND

Understanding of the behavioural and social drivers (BeSD) of vaccination is key to addressing vaccine hesitancy and accessibility issues. Vietnam's national COVID-19 vaccination programme resulted in high uptake of primary doses among adults, but lower booster doses for adults and primary doses for 5-11 years. This scoping review assessed BeSD influencing COVID-19 vaccine uptake in Vietnam to design interventions on reaching the national vaccination targets.

METHOD

We conducted a scoping review by searching PubMed, MedRxiv, LitCOVID, COVID-19 LOVE platform, WHO's COVID-19 research database and seven dominant Vietnamese language medical journals published in English or Vietnamese between 28 December 2019 and 28 November 2022. Data were narratively synthesised and summarised according to the four components of the WHO BeSD framework. The drivers were then mapped along the timeline of COVID-19 vaccine deployment and the evolution of the pandemic in Vietnam.

RESULTS

We identified 680 records, of which 39 met the inclusion criteria comprising 224 204 participants. Adults' intention to receive COVID-19 vaccines for themselves (23 studies) ranged from 58.0% to 98.1%. Parental intention to vaccinate their under 11-year-old children (six studies) ranged from 32.8% to 79.6%. Key drivers of vaccination uptake were perceived susceptibility and severity of disease, perceived vaccine benefits and safety, healthcare worker recommendation, and positive societal perception. Commonly reported COVID-19 vaccines' information sources (six studies) were social and mainstream media (82%-67%), television (72.7%-51.6%) and healthcare workers (47.5%-17.5%). Key drivers of COVID-19 uptake remained consistent for both adults and children despite changes in community transmission and vaccine deployment.

CONCLUSION

Key enablers of vaccine uptake for adults and children included perceived disease severity, perceived vaccine benefits and safety and healthcare worker recommendations. Future studies should assess vaccine communication targeted to these drivers, national policies and political determinants to optimise vaccine uptake.

Afraid but misinformed: Conspiracist beliefs cancel the positive influence of fear of COVID-19 on vaccination intentions - Findings from a Romanian sample

Understanding the factors that make people more likely to refuse vaccination against COVID-19 is crucial in order to design public health messages efficient in increasing vaccination rates. As COVID-19 creates risks of seriously damaging health effects, fear of this disease is as a significant determinant of vaccination intentions, as indicated by past research. Nevertheless, this positive influence may be limited in people who do not consider vaccines as a solution to protect against COVID-19, especially those who hold conspiracist beliefs about the new coronavirus and, implicitly, about the newly developed vaccines. The present study examined in a cross-sectional design on a convenience sample (N = 564) the joint effect of fear of COVID-19 and conspiracist beliefs on vaccination intentions, advancing past research on their independent influences. Furthermore, we investigated and controlled the effects of perceived risk of catching COVID-19, trust in medical experts, attitude towards vaccination and socio-demographical characteristics (i.e., gender, age, and education), previously found to be associated to COVID-19 vaccination intentions. We also tested the effect of ambivalence towards vaccination, i.e., the degree to which people simultaneously hold positive and negative evaluations of this intervention, as the widespread misinformation on the new coronavirus and its vaccines may induce ambivalence on this latter issue in many people. The results showed that the positive effect of fear of COVID-19 on vaccination intentions emerged only in participants who tend not to endorse conspiracist ideas on the new coronavirus. Moreover, higher vaccine hesitancy was found in participants with higher ambivalence towards vaccination, in those who perceive the risk of being contaminated by the new coronavirus as low, and in those with more negative attitudes towards vaccines in general. Vaccine ambivalence also emerged as a mediator of the negative effects of conspiracist beliefs about COVID-19 on vaccination intentions. This pattern of findings suggests the public messages emphasizing the risks of COVID-19 should also combat misinformation in order to maximize vaccine uptake.

Perception and Acceptance of COVID-19 Vaccine Among Healthcare Workers in Jeddah, Saudi Arabia

Introduction The COVID-19 pandemic has resulted in significant hospitalizations and deaths, particularly among healthcare workers (HCWs). Various therapeutic and preventive measures have been introduced, with vaccination considered the primary preventive measure. This study aims to assess the perceptions and acceptance of COVID-19 vaccination among HCWs. Methods We conducted an analytical cross-sectional study on HCWs in hospitals located in Jeddah, Saudi Arabia. The study included physicians, nurses, pharmacists, lab technicians, and radiologists who work in the Ministry of Health's general hospitals. A total of 394 participants were included in the study. Data were analyzed using SPSS v26, and a p-value less than 0.05 was considered significant. Results A majority of the participants (72.6%) were female, aged between 31-40 years (55.3%), and married (59.6%). More than half of the participants (55.6%) had received training on dealing with COVID-19. The mean scores for COVID-19 vaccine refusal, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and perceived effectiveness of COVID-19 vaccination were 18.36 ± 7.02, 14.48 ± 3.62, 11.51 ± 2.99, 12.39 ± 3.5, 8.25 ± 2.35, and 8.40 ± 2.46, respectively. Age was found to be correlated with the perceived severity of COVID-19 in non-vaccination (p=0.048), while gender was associated with the perceived severity of COVID-19 (p=0.015). Marital status (p=0.001), years of experience (p=0.009), profession (p=0.019), and education (p=0.028) were found to be correlated with perceived susceptibility. Education levels were found to be correlated with the perceived benefits of vaccination (p=0.007), perceived barriers to vaccines (p=0.002), and vaccine views (p=0.002). Years of experience (p=0.017) were found to be correlated with perceived severity of COVID-19, while profession type was significantly associated with perceived severity of COVID-19 (p=0.016) and vaccine view (p=0.008) Conclusion The study found that participants had a positive perception and high acceptance of COVID-19 vaccination. The results also indicated that various sociodemographic factors were associated with the perception and acceptance of COVID-19 vaccines among HCWs. These findings could help in formulating effective strategies to improve vaccination uptake rates among HCWs, thereby reducing transmission and mortality among Health Care Workers due to COVID-19.
