Acceptability of COVID-19 Vaccine Among Hospital Employees in the Department of Paediatrics, Gynaecology and Obstetrics in the University Hospitals of Geneva, Switzerland

COVID-19 Vaccine Acceptance Among Parents of Children With Multisystem Inflammatory Syndrome in Children

Data on COVID-19 vaccine acceptability among parents of children with multisystem inflammatory syndrome (MIS-C) are limited. In this cohort of children with MIS-C, enrolled in the Swissped RECOVERY trial (NCT04826588), comparing intravenous immunoglobulins or methylprednisolone, who, in accordance with Swiss guidelines, were recommended for SARS-CoV-2 vaccination, 65% (73/112) of parents reported being vaccinated against SARS-CoV-2 before the MIS-C, while 70% were vaccinated after the MIS-C episode of their child. None of the children were vaccinated before the occurrence of the MIS-C, and only 9% (5/56) received the COVID-19 vaccine after the MIS-C. The predominant barriers to COVID-19 vaccination were concerns over potential side effects and insufficient support from their doctors. This emphasizes the crucial role of health care providers in promoting COVID-19 vaccination among children.

COVID-19 vaccine hesitancy: A Systematic review of cognitive determinants

Background: Although mass vaccination is considered one of the most effective public health strategies during the pandemic, in the COVID-19 era, many people considered vaccines unnecessary and, or doubted the effectiveness of the COVID-19 vaccine. This review aimed to tabulate cognitive causes of COVID-19 vaccination hesitancy, which may help public health policymakers overcome the barriers to mass vaccinations in future pandemics. Methods: For this systematic review, studies pertaining to COVID-19 vaccine hesitancy published up to June 2022 were retrieved from six online databases (Cochrane Library, Google Scholar Medline through PubMed, Scopus, and Web of Science). Inclusion criteria were the studies conducted on people who had a delay in accepting or refusing COVID-19 vaccines, reported the impact of cognitive determinants on vaccine hesitancy, and were written in English in the timeframe of 2020-2022. Results: This systematic review initially reviewed 1171 records. From these 91 articles met the inclusion criteria. The vaccination hesitation rate was 29.72% on average. This systematic review identified several cognitive determinants influencing vaccination hesitancy. Lack of confidence and complacency were the most frequent factors that predicted vaccine hesitancy. Conclusion: The identified prevailing cognitive determinants for COVID-19 vaccine hesitancy indicated that using initiative and effective communication strategies would be a determinant factor in building people's trust in vaccines during the pandemic and mass vaccinations.

Healthcare Workers' Attitudes towards Mandatory COVID-19 Vaccination: A Systematic Review and Meta-Analysis

BACKGROUND

COVID-19 vaccine mandates are considered a controversial public health policy both in public debate and among healthcare workers (HCWs). Thus, the objective of this systematic review is to give a deep insight into HCWs' views and attitudes towards COVID-19 vaccination mandates amid the ongoing COVID-19 pandemic.

METHODS

A systematic literature search of five databases (PubMed, Scopus, Embase, CINAHL, and Web of Science) was conducted between July 2022 and November 2022. Original quantitative studies that addressed the attitudes of HCWs regarding COVID-19 vaccine mandates were considered eligible for this systematic review. All the included studies (n = 57) were critically appraised and assessed for risk of systematic bias. Meta-analyses were performed, providing a pooled estimate of HCWs' acceptance towards COVID-19 vaccine mandates for: 1. HCWs and 2. the general population.

RESULTS

In total, 64% (95% CI: 55%, 72%) of HCWs favored COVID-19 vaccine mandates for HCWs, while 50% (95% CI: 38%, 61%) supported mandating COVID-19 vaccines for the general population.

CONCLUSIONS

Our findings indicate that mandatory vaccination against COVID-19 is a highly controversial issue among HCWs. The present study provides stakeholders and policy makers with useful evidence related to the compulsory or non-compulsory nature of COVID-19 vaccinations for HCWs and the general population. Other: The protocol used in this review is registered on PROSPERO with the ID number: CRD42022350275.

Confidence in a Vaccine against COVID-19 among Registered Nurses in Barcelona, Spain across Two Time Periods

OBJECTIVE

To report the vaccine hesitancy (VH) for a vaccine against COVID-19 in registered nurses in Barcelona, with measurements taken at two stages, prior to the vaccination campaign and once 75% vaccination coverage had been reached.

METHODS

A self-completed online survey was administered in December 2020 and again in July 2021 through the College of Nurses of Barcelona. It measured the prevalence of VH against a government-approved vaccine recommended by their employer, their intention to be vaccinated, perceptions of disease risk and vaccine protection, attitudes and beliefs to vaccination and social norm. Bivariate analysis according to VH and application time are presented.

RESULTS

2430 valid responses were obtained in the first measurement and 2027 in the second. At both times, 86% were women and 69% worked mainly in the public sector. Prior to the vaccine availability, VH was 34.2%, decreasing to 17.9%. Risk perceptions were significantly lower in those with VH compared to non-VH, in all groups studied and at both times, while safety and efficacy perceptions increased in all groups, significantly less in VH. The greatest benefit of the COVID-19 vaccine is perceived by pharmaceutical companies. VH nurses perceived a more hesitant social environment.

CONCLUSION

As the vaccination was rolled out, VH in nurses declined, with time improving the confidence in the safety and efficacy of the vaccines. Risk perceptions also decreased over time, except for the perception of severity in HCW where it increased. Trust in institutions impacts trust in vaccines.

The impact of COVID-19 on hospital-based workers influenza vaccination uptake: A two-year retrospective cohort study

OBJECTIVES

This study aimed at exploring 2020/2021 and 2019/2020 seasonal influenza vaccine uptake among healthcare and non-healthcare workers, hereafter hospital-based workers (HBWs); examining attitudes and motivations for uptake in the 2020/2021 season; and exploring the amount, types, and sources of information used by HBWs.

METHODS

A retrospective cohort study. Socio-demographics, working profile, working area, and vaccination status data were collected. Motivations for vaccination uptake in the 2020/2021 season were also explored. Descriptive and inferential statistics were used.

RESULTS

Overall, uptake increased from 14.8% in 2019/2020 to 31.7% in 2020/2021. Male workers show greater vaccination uptake than their female counterparts (20.4% vs. 12.6% in 2019/2020, and 36.5% vs. 29.8% in 2020/2021). Uptake increased for healthcare assistants (+8.9%), administrative/managerial staff (+17%), nurses/midwives (+17.1%), non-medical graduate staff (+22.8%), and physicians (+33.2%), while it decreased slightly for resident physicians despite still being one of the most vaccinated categories (-4.6%). Main reasons for vaccination were the desire to protect patients (33.0%) and relatives (51.1%). Lastly, 60.8% of HBWs relied on institutional sources of information; the remainder relied on non-institutional sources including social media and chatting with colleagues.

CONCLUSIONS

Vaccination uptake increased in the 2020/21 season. Tailored educational interventions are required on the impact of influenza in care settings, vaccine efficacy, and vaccination safety. Investments in improving HBWs' reliance on institutional sources, and their ability to find them, are also needed.
