Vaccine hesitancy and self-vaccination behaviors among nurses in southeastern France

Vaccine-Preventable Disease Outbreaks among Healthcare Workers: A Scoping Review

BACKGROUND

Outbreaks of vaccine preventable diseases (VPDs) in health care workers (HCWs) can result in morbidity and mortality and cause significant disruptions to health care services, patients and visitors as well as an added burden on the health system. This scoping review is aimed to describe the epidemiology of VPD outbreaks in HCW, caused by diseases which are prevented by the ten vaccines recommended by World Health Organization (WHO) for HCWs.

METHODS

In April 2022 CINAHL, MEDLINE, Global Health and EMBASE were searched for all articles reporting on VPD outbreaks in HCWs since the year 2000. Articles were included regardless of language and study type. Clinical and epidemiological characteristics of VPD outbreaks were described.

RESULTS

Our search found 9363 articles, of which 216 met inclusion criteria. Studies describing six of the ten VPDs were found: influenza, measles, varicella, tuberculosis, pertussis and rubella. Most articles (93%) were from high- and upper middle-income countries. While most outbreaks occurred in hospitals, several influenza outbreaks were reported in long term care facilities. Based on available data, vaccination rates amongst HCWs were rarely reported.

CONCLUSION

We describe several VPD outbreaks in HCWs from 2000 to April 2022. The review emphasises the need to understand the factors influencing outbreaks in HCWs and highlight importance of vaccination amongst HCWs.

Effectiveness of interventions to increase healthcare workers' adherence to vaccination against vaccine-preventable diseases: a systematic review and meta-analysis, 1993 to 2022

BackgroundVaccination adherence among healthcare workers (HCWs) is fundamental for the prevention of vaccine-preventable diseases (VPDs) in healthcare. This safeguards HCWs' well-being, prevents transmission of infections to vulnerable patients and contributes to public health.AimThis systematic review and meta-analysis aimed to describe interventions meant to increase HCWs' adherence to vaccination and estimate the effectiveness of these interventions.MethodsWe searched literature in eight databases and performed manual searches in relevant journals and the reference lists of retrieved articles. The study population included any HCW with potential occupational exposure to VPDs. We included experimental and quasi-experimental studies presenting interventions aimed at increasing HCWs' adherence to vaccination against VPDs. The post-intervention vaccination adherence rate was set as the main outcome. We included the effect of interventions in the random-effects and subgroup meta-analyses.ResultsThe systematic review considered 48 studies on influenza and Tdap vaccination from database and manual searches, and 43 were meta-analysed. A statistically significant, positive effect was seen in multi-component interventions in randomised controlled trials (relative risk (RR) = 1.37; 95% CI: 1.13-1.66) and in observational studies (RR = 1.43; 95% CI: 1.29-1.58). Vaccination adherence rate was higher in community care facilities (RR = 1.58; 95% CI: 1.49-1.68) than in hospitals (RR = 1.24; 95% CI: 0.76-2.05).ConclusionInterventions aimed at increasing HCWs' adherence to vaccination against VPDs are effective, especially multi-component ones. Future research should determine the most effective framework of interventions for each setting, using appropriate study design for their evaluation, and should compare intervention components to understand their contribution to the effectiveness.

Attitudes of healthcare workers toward the COVID-19 vaccine and related factors: A systematic review

AIM AND OBJECTIVES

This systematic review aims to examine healthcare professionals' attitudes toward the COVID-19 vaccine and related factors.

BACKGROUND

Healthcare workers have priority among risky groups accepted as candidates for early vaccination. Therefore, it is important to consider health professionals' attitudes toward COVID-19 vaccination to better address barriers to widespread vaccination.

MATERIALS AND METHODS

Six databases were searched for articles published between January 01, 2020, and February 31, 2022, and 1161 studies were reached. As a result of the evaluations, 10 studies were included in the systematic review. Nine studies are cross-sectional, and one is a descriptive study. A 9-item Critical Appraisal Checklist for Analytical Cross Sectional Studies from the Joanna Briggs Institute MAStARI Critical Assessment Tools (JBI-MAStARI) was used for quality assessment. High-quality studies with an average or higher methodological quality score were included in the systematic review. The PRISMA guideline was followed while selecting studies.

RESULTS

Positive attitudes of healthcare professionals toward the COVID-19 vaccine ranged from 10% to 93.7%, and negative attitudes varied between 6.3% and 41.0%. Factors such as the male gender, being a physician, advanced age, previous influenza vaccination history, and presence of chronic disease were found to be associated with vaccine acceptance. Factors such as doubt about the efficacy of the COVID-19 vaccine, safety concerns, and fear of unknown side effects of the vaccine were associated with COVID-19 vaccine hesitancy.

CONCLUSION

There is a need for confidence-building interventions and tailored communication strategies, including personalized training to change the ambiguous attitudes of healthcare professionals, increase vaccine uptake, and cope with the multifaceted impact of infection.

Gap between cognitions and behaviors among children's guardians of influenza vaccination: The role of social influence and vaccine-related knowledge

The seasonal influenza vaccine coverage remains suboptimal among children even though guardians expressed high willingness to vaccinate their children. This study aimed to determine the association between vaccine hesitancy and uptake to facilitate vaccination; thus, bridging the gap. A cross-sectional design, using stratified cluster random sampling, was conducted among guardians of 0-59-month-old Chinese children from July to October in 2019. A structural equation model was applied to explore the interrelationships between factors including vaccine hesitancy, vaccination, social influence, and relative knowledge among guardians. Of the 1,404 guardians, 326 were highly hesitant to vaccinate their children, 33.13% (108/326) of whom had vaccinated their children. Moreover, 517 and 561 guardians had moderate and low vaccine hesitancy, with corresponding vaccine coverage of 42.75% (221/517) and 47.95% (269/516). Guardians' gender, age, and education level were demographic variables with significant moderating effects. Social influence considered impact of communities, family members, friends, neighbors, healthcare workers, bad vaccination experience and sense on price. Actual vaccine uptake was negatively significantly associated with hesitancy (β = -0.11, p < .001) with positive association with social influence (β = 0.61, p < .001). Vaccine hesitancy was negatively significantly associated with relative knowledge (β = -2.14, p < .001) and social influence (β = -1.09, p < .001). A gap is noted between cognitions and behaviors among children's guardians regarding influenza vaccination. A comprehensive strategy including emphasizing benefits of the influenza vaccination, risk of infection, and ensuring high vaccine confidence among healthcare workers can help transform the willingness to engage in the behavior of vaccination.

Vaccine Hesitancy among Healthcare Workers in Europe: A Systematic Review

This study analyzes vaccine hesitancy (VH) among healthcare workers (HCWs) in 15 European countries. We have undertaken a systematic review by synthesizing data from 46 articles (between 2015 and 2022) encompassing 55,612 subjects. Despite the heterogeneity of the methods in the various studies, we found that physicians had consistently higher vaccination rates than nurses across different countries and different vaccines. Physicians' average vaccination rate was 79% across a selection of vaccines, while that of nurses was 62%. Concerns regarding vaccine safety, information gaps, and the responsibility of healthcare authorities in managing VH are highlighted by qualitative insights. This research contributes to our comprehension of the ways in which VH among HCWs is impacted by healthcare roles, vaccine types, and regional disparities. The insights gleaned from this analysis can serve as a guide for targeted interventions aimed at increasing vaccine acceptance and coverage in Europe, ultimately strengthening public health.

Influenza vaccine coverage among healthcare workers: A cluster analysis from a cross-sectional survey

OBJECTIVES

Influenza vaccination is recommended for healthcare workers (HCWs). However, in a 1500-bed tertiary care university hospital in France, influenza vaccine coverage among HCWs was 23% in 2017.

PATIENTS AND METHODS

We performed a cross-sectional study between 05/09/2018 and 25/09/2018 among HCWs, randomly selected independent of their vaccination status, to estimate influenza vaccination coverage rate during the 2017-2018 season, and explore factors influencing vaccination, using a questionnaire. Multivariable regression analysis to assess factors associated with vaccine uptake and hierarchical clustering on principal components to identify HCW profiles regarding factors influencing vaccine uptake, were performed after multiple imputation.

RESULTS

977 HCWs were included (68% participation rate), primarily females (84%), nurses (38%) of 18-39 years old. Influenza vaccination coverage rate reached 33[30-36]%. Frequent vaccination (aOR 39.27[21.52-74.51]) and personal/family medical history of influenza (aOR 3.33[1.16-10.02]) were independently associated with vaccination. In HCWs' patterns of influenza vaccination status, three clusters were identified: 1) (n = 438) mostly vaccinated (70%); 2) (n = 507) most unvaccinated (97%); and 3) (n = 32) unvaccinated HCWs lacking knowledge on influenza and influenza vaccine. Among the 148 (15%) HCWs reluctant to receive the vaccine the following year, 23 (16%) received it for the 2017-2018 season, while 125 (84%) did not, mostly stating they had doubts about the vaccine (82%).

CONCLUSION

This work identifies determinants of vaccine uptake and highlights HCWs profiles associated with factors influencing vaccination and a subgroup of HCWs flexible about having the vaccine during the upcoming seasonal campaign. This result opens up perspectives toward improved vaccination coverage among HCWs.

Predictors of second COVID-19 booster dose or new COVID-19 vaccine hesitancy among nurses: A cross-sectional study

AIMS AND OBJECTIVES

To assess the levels of second COVID-19 booster dose/new COVID-19 vaccine hesitancy among nurses and explore the potential predictors of vaccine hesitancy.

BACKGROUND

COVID-19 full vaccination seems to be highly effective against highly contagious variants of SARS-CoV-2. Healthcare workers are at high-risk group since they have experienced high levels of COVID-19-associated morbidity and mortality.

DESIGN

An on-line cross-sectional study was carried out in Greece in May 2022, using a self-administered questionnaire.

METHODS

The study population included nurses in healthcare services who were fully vaccinated against COVID-19 at the time of study. We considered socio-demographic characteristics, COVID-19-related variables, and attitudes toward COVID-19 vaccination and pandemic as potential predictors of vaccine hesitancy. We applied the STROBE checklist in our study.

RESULTS

Among 795 nurses, 30.9% were hesitant toward a second booster dose or a new COVID-19 vaccine. Independent predictors of hesitancy included lower educational level, absence of a chronic condition, good/very good self-perceived physical health, lack of flu vaccination during 2021, front-line nurses that provided healthcare to COVID-19 patients, nurses that had not been diagnosed with COVID-19 and nurses that had at least one relative/friend that has died from COVID-19. Moreover, increased compliance with hygiene measures, increased fear of a second booster dose/new COVID-19 vaccine and decreased trust in COVID-19 vaccination were associated with increased hesitancy.

CONCLUSIONS

Our study shows that a significant percentage of nurses are hesitant toward a second booster dose/new COVID-19 vaccine. This initial hesitancy could be a barrier to efforts to control the COVID-19 pandemic.

RELEVANCE TO CLINICAL PRACTICE

Nurses' role during the COVID-19 pandemic is essential since they are the front-line healthcare workers empowering the public with their passion and empathy. There is a need to communicate COVID-19 vaccine science in a way that is accessible to nurses in order to decrease COVID-19 vaccine hesitancy.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution.

Healthcare workers' (HCWs) attitudes and related factors towards COVID-19 vaccination: a rapid systematic review

Herd immunity through vaccination is a key measure to control COVID-19 pandemic. However, vaccine hesitancy remains a public health threat, which is still common among healthcare workers (HCWs). This systematic review aimed to synthesise evidence on HCWs' attitudes towards COVID-19 vaccination and analyse associated factors to provide information for vaccine policy development and practice. We searched PubMed, Embase, ScienceDirect, Web of Science and three Chinese databases for literature published on 12 February 2021. Two researchers screened the literature independently, and 13 studies were included in the systematic review. Vaccine acceptance varied widely and ranged from 27.7% to 77.3%. HCWs had positive attitudes towards future COVID-19 vaccines, while vaccine hesitancy was still common. Demographic variables such as men, older age and physicians were positive predictive factors. Women and nurses had more vaccine hesitancy. Previous influenza vaccination and self-perceived risk were facilitators. Concerns for safety, efficacy and effectiveness and distrust of the government were barriers. Influences of direct (COVID-19) patient care towards vaccination intention were less conclusive. Tailored communication strategies were needed to increase the uptake rate of COVID-19 vaccines among HCWs. More importantly, more data and information on the safety and efficacy of vaccines should be provided with transparency.

Narrative versus statistical messages: The interplay of perceived susceptibility and misperceptions on vaccine intention

Although there is enough scientific evidence to show the benefits and safety of vaccines, vaccine rates are low, while misperceptions about vaccines are on the rise. The main purposes of the current study are to 1) examine the effects of narrative vs. statistical messages on vaccine intention, 2) test the mediating role of perceived expectancies, and 3) examine the moderating roles of perceived susceptibility and misperceptions on vaccine intention. Data were collected with an online experiment through Amazon Mturk. The online experiment was conducted via Qualtrics once the study was considered exempt by the Institutional Research Board of a large University in the U.S. A total of 300 participants aged 18 and above completed the survey. Findings show that perceived expectancies mediate the relationship between message manipulation and vaccine intention. Our findings also show a three-way interaction which indicates that among individuals with high misperceptions, statistical messages are more persuasive for individuals with high perceived susceptibility, while narrative messages are more influential for individuals with low perceived susceptibility.

Promoting HPV vaccination at school: a mixed methods study exploring knowledge, beliefs and attitudes of French school staff

BACKGROUND

HPV vaccine coverage in France remained lower than in most other high-income countries. Within the diagnostic phase of the national PrevHPV program, we carried out a mixed methods study among school staff to assess their knowledge, beliefs and attitudes regarding HPV, HPV vaccine and vaccination in general, and regarding schools' role in promoting HPV vaccination.

METHODS

Middle school nurses, teachers and support staff from four French regions participated between January 2020 and May 2021. We combined: (i) quantitative data from self-administered online questionnaires (n = 301), analysed using descriptive statistics; and (ii) qualitative data from three focus groups (n = 14), thematically analysed.

RESULTS

Less than half of respondents knew that HPV can cause genital warts or oral cancers and only 18% that no antiviral treatment exists. Almost 90% of the respondents knew the existence of the HPV vaccine but some misunderstood why it is recommended before the first sexual relationships and for boys; 56% doubted about its safety, especially because they think there is not enough information on this topic. Schools nurses had greater knowledge than other professionals and claimed that educating pupils about HPV was fully part of their job roles; however, they rarely address this topic due to a lack of knowledge/tools. Professionals (school nurses, teachers and support staff) who participated in the focus groups were unfavourable to offering vaccination at school because of parents' negative reactions, lack of resources, and perceived uselessness.

CONCLUSIONS

These results highlight the need to improve school staff knowledge on HPV. Parents should be involved in intervention promoting HPV vaccination to prevent their potential negative reactions, as feared by school staff. Several barriers should also be addressed before organizing school vaccination programs in France.

Relation of Personal Characteristics with Human Papillomavirus Vaccination Outcomes: Assessing the Mediating Role of Vaccine Hesitancy Dimensions

Recent findings suggest that the rate of certain cancers can be reduced by increasing human papillomavirus (HPV) vaccination coverage, resulting in considerable research interest on the antecedents of HPV vaccine receipt to identify avenues to promote vaccination. The current article continues this stream of research by (1) studying the three HPV vaccination outcomes of willingness, receipt, and word-of-mouth, (2) investigating the antecedent effects of sociodemographic characteristics, health insurance status, provider conversation, and political orientation, and (3) testing the mediating role of vaccine hesitancy dimensions using a recently developed conceptualization. We achieve these goals by conducting a cross-sectional study with 404 participants (Agemean = 37.64; AgeSD = 14.91; 57% female; 72% white; 100% located in U.S.). Our results show that provider conversations and political orientation had the most consistent and strong effects of the personal characteristics, whereas perceptions that vaccines pose health risks and perceptions that vaccines are not needed for healthy individuals produced the most consistent and strong effects of the vaccine hesitancy dimensions. Other personal characteristics and vaccine hesitancy dimensions also produced intermittent significant effects, including age, education, and race. Together, these results support that personal characteristics and vaccine hesitancy dimensions relate to a broader range of outcomes associated with HPV vaccination than previously known, and these results also support that the recently developed conceptualization of vaccine hesitancy is apt for understanding HPV vaccine perceptions. Our discussion concludes with highlighting avenues for future research and practice that can leverage our discovered relations to improve HPV vaccination outcomes.

Perceptions and Cues to Action as Predictors of Nurses' Vaccination Intentions at Two Primary Health Care Facilities in Ghana

Uptake of hepatitis B vaccination by health care providers remains suboptimal in Ghana, although it is considered an effective strategy against the hepatitis B virus. This study aimed to identify the predictors of nurses' hepatitis B vaccination intentions at two municipal health care facilities in Ghana. A descriptive cross-sectional survey was adopted. A section of the health belief model-based questionnaire was administered to 181 nurses conveniently sampled from the two facilities. Data analysis was done using Statistical Product and Service Solutions software version 23.0. Frequencies and percentages were used to assess the demographic characteristics of participants. Pearson r coefficients were used to assess the intercorrelations between individual perceptions, and the cues to action on vaccination intentions. Simple and multiple regression was used to estimate the prediction of individual perceptions, and the cues to action on hepatitis B vaccination intentions of nurses. The findings showed that nurse-perceived benefits and cues to action were positive and significantly related to hepatitis B vaccination intentions of nurses (r = 0.14, P < 0.05; r = 0.17, P < 0.05). Perceived susceptibility and perceived barrier were negative and significantly related to vaccine intentions (r = -0.13, P < 0.05; r = -0.24, P < 0.01). Notably, perceived barrier predicted hepatitis B vaccination intentions (β = -0.22, t = -2.48, P = 0.01). Nurses' vaccination behavioral intentions were positive. It was recommended that perceived barriers to hepatitis B vaccination such as vaccination ineffectiveness, time constraints, high costs, and side effects should be addressed to increase nurses' vaccination uptake.

International adaptation and validation of the Pro-VC-Be: measuring the psychosocial determinants of vaccine confidence in healthcare professionals in European countries

BACKGROUND

Healthcare professionals (HCPs) play an important role in vaccination; those with low confidence in vaccines are less likely to recommend them to their patients and to be vaccinated themselves. The study's purpose was to adapt and validate long- and short-form versions of the International Professionals' Vaccine Confidence and Behaviors (I-Pro-VC-Be) questionnaire to measure psychosocial determinants of HCPs' vaccine confidence and their associations with vaccination behaviors in European countries.

RESEARCH DESIGN AND METHODS

After the original French-language Pro-VC-Be was culturally adapted and translated, HCPs involved in vaccination (mainly GPs and pediatricians) across Germany, Finland, France, and Portugal completed a cross-sectional online survey in 2022. A 10-factor multigroup confirmatory factor analysis (MG-CFA) of the long-form (10 factors comprising 34 items) tested for measurement invariance across countries. Modified multiple Poisson regressions tested the criterion validity of both versions.

RESULTS

2,748 HCPs participated. The 10-factor structure fit was acceptable to good everywhere. The final MG-CFA model confirmed strong factorial invariance and showed very good fit. The long- and short-form I-Pro-VC-Be had good criterion validity with vaccination behaviors.

CONCLUSION

This study validates the I-Pro-VC-Be among HCPs in four European countries; including long- and short-form tools for use in research and public health.

Impact of COVID-19 pandemic on flu vaccine uptake in healthcare workers in Europe: a systematic review and meta-analysis

INTRODUCTION

Influenza immunization policies in Europe primarily target at-risk and vulnerable subjects. Healthcare workers (HCWs) are a key focus of vaccination campaigns. Our systematic review and meta-analysis aim to evaluate the role of the COVID-19 pandemic on influenza vaccine uptake among HCWs since the 2020/21 influenza season.

AREAS COVERED

Fourteen studies were included in the meta-analysis and systematic review, selected from scientific articles available in MEDLINE/PubMed, ISI Web of Knowledge, and Scopus databases between 1 January 2021 and 15 January 2023 The analysis revealed a significant relationship between influenza vaccine uptake and COVID-19 related determinants, such as willingness to receive COVID-19 vaccination, fear of COVID-19, and differentiating between influenza and COVID-19 symptoms (OR = 5.70; 95%CI = 2.08-15.60). Several studies reported higher vaccination coverages in the 2020/21 season compared to previous seasons, with VC values ranging from + 17% to + 38% compared to the 2019/20 season. The included studies identified a shift in HCWs' attitudes toward influenza vaccination, attributed to increased awareness due to the COVID-19 pandemic.

EXPERT OPINION

Vaccine hesitancy is common among HCWs in Europe, necessitating mutual strategies across all European countries. So far, mandatory vaccination policies have shown the most potential in achieving high and sustainable influenza vaccination rates among HCWs.

Factors influencing healthcare professionals' confidence in vaccination in Europe: a literature review

Health-care professionals (HCPs) have a fundamental role in vaccination, their own beliefs and attitudes affecting both their uptake and recommendation of vaccines. This literature review (n = 89) summarises evidence on HCPs’ perceptions of the risks and benefits of vaccination, trust, and perceptions of mandatory vaccination in Europe. HCPs across studies believed that vaccination is important to protect themselves and their patients. However, beliefs that some diseases such as influenza are less risky were reported by some HCPs as a reason for not getting vaccinated. Concerns about both short- and long-term side effects were identified among HCPs in most studies, such as those affecting the immune or neurological system. Mistrust toward health authorities and pharmaceutical industry was reported in some studies. The question of mandatory vaccination revealed mixed opinions, with some favoring self-determination and others viewing vaccination as a duty. This review highlights key factors influencing HCPs’ confidence in vaccination in Europe.

Vaccine or Garlic-Is It a Choice? Awareness of Medical Personnel on Prevention of Influenza Infections

BACKGROUND

Preventing the spread of the influenza virus is one of the primary health policy challenges of many countries worldwide. One of the more effective ways to prevent infection is influenza vaccination, and the people who enjoy the most public confidence in preventive health care are health workers (HWs). For this reason, it is crucial to study the attitudes of HWs toward influenza vaccination.

METHODS

The survey was conducted among 950 medical (physicians and nurses) and administrative staff in three academic hospitals. Respondents to the survey were selected on a random-target basis to represent hospital employees in the study best. The survey was conducted using the PAPI method between August and September 2020.

RESULTS

Respondents considered hand washing (52.8%) and avoiding contact with sick people (49.3%) the most effective ways to prevent influenza infection. Three in ten respondents considered wearing a protective mask (30.1%) and getting vaccinated against influenza (29.9%) is fully effective in preventing influenza. Influenza vaccination as effective in preventing influenza virus infection was chosen more often by those who worked in a pediatric hospital. Nurses were twice less likely than physicians to declare that influenza vaccination prevents infection (42.4% for nurses vs. 84.0% for physicians). At the same time, 20.4% of nurses believed that eating garlic effectively prevented influenza infection, and 28.1% declared daily vitamin C helpful.

CONCLUSIONS

The study pointed to significant educational gaps regarding the role and effectiveness of influenza vaccination in the process of influenza virus infection and indicated a firm belief in medical myths, especially in the nursing community, related to protection against influenza virus infection.

Perception of COVID-19 and Vaccine Acceptance among Healthcare Workers

Background

COVID-19 infection is more likely to be acquired and transmitted by healthcare workers (HCWs). Furthermore, they serve as role models for communities in terms of COVID-19 vaccination attitudes. As a result, HCWs' reluctance to vaccinate could have a significant impact on pandemic containment efforts.

Aim

To characterize the current COVID-19 vaccine approval situation among healthcare workers and to determine the most likely reason for agreement or disagreement with COVID-19 vaccination.

Methods

This cross-sectional design included 451 HCWs from COVID-19 treatment institutions, with COVID-19 exposure risk changing depending on job function and working location.

Results

The study recruited 156 physicians and 295 nurses, of whom 58.1% were female and 41.9% were male. Physicians had a significantly higher rate of participation in COVID-19 pandemic prevention and control, with a rate of 69.9% versus 55.3% of nurses. Acceptance of COVID-19 vaccination was reported by 40.8% of HCWs. The rate of acceptance was significantly higher among physicians (55.1%) than among nurses (33.2%) (p < 0.001). Most HCWs (67.8%) believed the vaccine was not effective. Physicians showed more significant trust in the effectiveness of the vaccine than nurses (41% and 27.5, respectively) (p=0.003). Concerning vaccine safety, only 32.8% of HCWs believed it was safe. This was significantly higher in physicians (41.7%) than in nurses (28.1%) (p=0.004).

Conclusion

Vaccination uncertainty is common among healthcare personnel in Egypt, and this could be a significant barrier to vaccine uptake among the public. Campaigns to raise vaccine knowledge are critically needed.

A systematic literature review to clarify the concept of vaccine hesitancy

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.

Beliefs and Sociodemographic and Occupational Factors Associated with Vaccine Hesitancy among Health Workers

Introduction: Vaccine hesitancy has been implicated in the low-vaccination coverage in several countries. Knowledge about vaccine hesitancy predictors in health workers is essential because they play a central role in communication about the importance and safety of vaccines. This study aimed to assess beliefs and sociodemographic and occupational factors associated with vaccine hesitancy in health workers. Methods: This was a cross-sectional study among 453 health workers in primary and medium complexity services in a municipality in the state of Bahia, Brazil. The variable vaccine hesitancy was operationalized based on the answers related to incomplete vaccination against hepatitis B, measles, mumps and rubella, and diphtheria and tetanus. Associations between variables were expressed as prevalence ratios (PR) and their respective 95% confidence intervals (CI). Results: Endemic disease combat agents, administrative service workers, and support staff had the highest levels of vaccine hesitancy. Among the analyzed variables, the following were associated with vaccine hesitancy: working in secondary health care services (PR: 1.21; CI: 1.07-1.36), working as an endemic disease combat agent (PR = 1.42; 95% CI: 1.165-1.75), not sharing information about vaccines on social media (PR = 1.16; 95% CI: 1.05-1.28), distrusting information about vaccinations (PR: 0.86; CI: 0.75-0.99), and not feeling safe receiving new vaccines (PR = 1.16; 95% CI: 1.06-1.28). Conclusions: Strategies to enhance confidence in vaccination among health workers should consider differences in occupations and their working settings. Improving vaccination-related content in training and continuing education activities and facilitating access to onsite vaccinations at the workplace are crucial elements to reduce vaccine hesitancy among health workers.

Measuring psychosocial determinants of vaccination behavior in healthcare professionals: validation of the Pro-VC-Be short-form questionnaire

BACKGROUND

Vaccine confidence among health care professionals (HCPs) is a key determinant of vaccination behaviors. We validate a short-form version of the 31-item Pro-VC-Be (Health Professionals Vaccine Confidence and Behaviors) questionnaire that measures HCPs' confidence in and commitment to vaccination.

RESEARCH DESIGN AND METHODS

A cross-sectional survey among 2,696 HCPs established a long-form tool to measure 10 dimensions of psychosocial determinants of vaccination behaviors. Confirmatory factor analysis (CFA) models tested the construct validity of 69,984 combinations of items in a 10-item short form tool. The criterion validity of this tool was tested with four behavioral and attitudinal outcomes using weighted modified Poisson regressions. An immunization resource score was constructed from summing the responses of the dimensions that can influence HCPs' pro-vaccination behaviors: vaccine confidence, proactive efficacy, and trust in authorities.

RESULTS

The short-form tool showed good construct validity in CFA analyses (RMSEA = 0.035 [0.024; 0.045]; CFI = 0.956; TLI = 0.918; SRMR 0.027) and comparable criterion validity to the long-form tool. The immunization resource score showed excellent criterion validity.

CONCLUSIONS

The Pro-VC-Be short-form showed good construct validity and criterion validity similar to the long-form and can therefore be used to measure determinants of vaccination behaviors among HCPs.

COVID-19 vaccine hesitancy and intent in California registered nurses

Despite a national vaccination effort prioritizing frontline healthcare workers, COVID-19 vaccination rates among nurses have been lower than necessary to protect workforce and patient health. Historically, nurses have been more vaccine hesitant than other healthcare workers. To assess the vaccine attitudes and COVID-19 vaccine intent of California's registered nurses, we conducted a statewide cross-sectional survey among 603 licensed RNs working in direct patient care. Of 167 respondents (27.7%), 111 met inclusion criteria. Their mean score of 3.01 on a 6-point rating scale on the Vaccine Attitudes Examination scale measuring general vaccine hesitancy was comparable to previous findings among U.S. West Coast adults. Greater vaccine hesitancy was significantly associated with lower COVID-19 vaccine intent, after controlling for relevant confounders. Since nurses make up the largest portion of the healthcare workforce, it is crucial to specifically address this group's vaccine hesitancy.

Pilot Study of Evaluating Attitudes toward Childhood Immunization among Healthcare Workers in Japan

Providing appropriate immunization information during the perinatal period is important for improving immunization rates among infants and children; however, the distribution of immunization information by healthcare workers (HCWs) is not standardized in Japan. We investigated HCWs’ attitudes toward childhood immunization and factors related to vaccine hesitancy. We conducted a cross-sectional descriptive survey of HCWs involved in childhood immunization in Niigata City, Japan, from November 2017 to January 2018. We assessed contextual, individual and group, and vaccine/vaccination-specific influences. Of 290 HCWs, 139 (47.9%) returned completed questionnaires. Most HCWs (87/139, 64.9%) reported providing immunization information verbally to parents; 51/87 (58.6%) spent fewer than five minutes doing so. Pediatricians provided vaccines based on the parents’ best interest, whereas public health nurses and midwives emphasized government policy. Nurses had greater hesitancy related to personal perceptions and social/peer factors than pediatricians (p < 0.001). Nurses were significantly more likely than pediatricians to suggest that children receive more shots than necessary (p < 0.01). Nurses tended to have more negative attitudes toward vaccination and little awareness of immunization promotion compared to pediatricians. Thus, all HCWs involved in childhood immunization should receive sufficient information to provide timely and appropriate immunization to infants and children.

Nurses’ Influenza Vaccination and Hesitancy: A Systematic Review of Qualitative Literature

Vaccine hesitancy (VH) is defined as “delaying or refusing a secure vaccine despite its availability”. This hesitancy affects caregivers and more specifically nurses. The purpose of this study is to assess determinants of influenza VH in the nurse’s community. We conducted a systematic review of qualitative literature according to criteria of Preferred Reporting Items for Systematic Review and Meta-Analysis and Enhancing Transparency in Reporting the synthesis of Qualitative Research from 2009 until October 2020. Eleven qualitative studies analysed (ten thematic content analyses and one grounded theory method) found three main factors in VH. The first determinant was the benefit–risk equation considered as unfavourable due to an ineffective vaccine and fears about adverse effects as the pain of the injection. Wrong immunological beliefs brought into hesitancy. Disease barriers (hand washing and masks) and personal immunity were regarded as more effective than the vaccine. Lastly, dehumanised vaccination and the difficulties of access to healthcare were institutional determinants. Nurses ask for a vaccine promotion by hierarchy and doctors with transparent information and respect for autonomy. The availability of vaccines and methods of pain control seem to be some tracks to reduce nurses’ VH.

Willingness and Influencing Factors to Receive COVID-19 Vaccination Among Chinese Medical Students

Objectives

The aim of this study is to evaluate the desire of medical students in China to get vaccinated or not get vaccinated and the reasons for either decision.

Methods

A cross-sectional survey was conducted from 11 March and 12 March 2021, by administering an online questionnaire to the Chinese medical students. Data entry and analysis were conducted using IBM SPSS ver. 26.0.

Results

Of 3,047 students who completed the survey, 37.9% (1,154) of participants indicated that they would be vaccinated against COVID-19, while 62.1% (1,893) declared that they would not. Attitudes to the COVID-19 vaccine (p = 0.000), levels of eHealth Literacy (p = 0.000), the impact of COVID19 (p = 0.000), concerns about the COVID-19 vaccine (p = 0.000) and gender (p = 0.000) strong associations with willingness to receive the COVID-19 vaccine.

Conclusion

The willingness to receive COVID-19 vaccination was sub-optimal among medical students in China. Educational interventions to improve medical students' perceptions and acceptance toward the COVID-19 vaccine are needed.

Vaccine hesitancy in health-care providers in Western countries: a narrative review

INTRODUCTION

Vaccine hesitancy (VH) is a leading cause of suboptimal vaccine uptake rates worldwide. The interaction between patients and health-care providers (HCPs) is the keystone in addressing VH. However, significant proportions of HCPs, including those who administer vaccines, are personally and professionally vaccine-hesitant.

AREAS COVERED

This narrative review sought to characterize the nature, extent, correlates, and consequences of VH among HCPs. We included 39 quantitative and qualitative studies conducted in Western countries, published since 2015, that assessed VH among HCPs in general, for several vaccines. Studies were reviewed using the WHO 3Cs model - (lack of) confidence, complacency, and (lack of) convenience.

EXPERT OPINION

Despite the lack of validated tools and substantial heterogeneity in the methods used to measure VH among HCPs, this review confirms its presence in this population, at frequencies that vary by country, profession type, setting, and level of medical education. Lack of knowledge and mistrust in health authorities/pharmaceutical industry/experts were among its principal drivers. Improving the content about vaccination in HCPs' training programs, facilitating access to reliable information for use during consultations, and developing and validating instruments to measure HCPs' VH and its determinants are key to addressing VH among HCPs.

Efficacy of a nurse-led patient education intervention in promoting safety skills of patients with inflammatory arthritis treated with biologics: a multicentre randomised clinical trial

Objective

To evaluate the effect of a nurse-led patient education on safety skills of patients with inflammatory arthritis treated with biologic disease-modifying antirheumatic drugs (bDMARDs).

Methods

This is a multicentre, open-labelled, randomised controlled trial comparing an intervention group (face-to-face education by a nurse at baseline and 3 months later) with a control group (usual care) at the introduction of a first subcutaneous bDMARD. The primary outcome was score on the BioSecure questionnaire at 6 months (0–100 scale), a validated questionnaire assessing competencies in dealing with fever, infections, vaccination and daily situations. The secondary outcomes were disease activity, coping, psychological well-being, beliefs about medication, self-efficacy and severe infection rate.

Results

129 patients with rheumatoid arthritis and spondyloarthritis were enrolled in nine rheumatology departments; 122 completed the study; 127 were analysed; and 64 received the intervention (mean duration: 65 min at baseline and 44 min at 3 months). The primary outcome was met: the BioSecure score was 81.2±13.1 and 75.6±13.0 in the education and usual care groups (difference: +6.2, 95% CI 1.3 to 11.1, p=0.015), demonstrating higher safety skills in the education group. Exploratory analyses showed better skills regarding infections, greater willingness for vaccinations and greater adherence-related behaviours in the education group. Coping was significantly more improved by education; other secondary outcomes were improved in both groups, with no difference.

Conclusions

Educating patients was effective in promoting patient behaviours for preventing adverse events with bDMARDs. An education session delivered to patients starting a first bDMARD can be useful to help them self-manage safety issues.

An instrument to measure psychosocial determinants of health care professionals' vaccination behavior: Validation of the Pro-VC-Be questionnaire

OBJECTIVES

The lack of validated instruments assessing vaccine hesitancy/confidence among health care professionals (HCPs) for themselves, and their patients led us to develop and validate the Pro-VC-Be instrument to measure vaccine confidence and other psychosocial determinants of HCPs' vaccination behavior among diverse HCPs in different countries.

METHODS

Cross-sectional survey in October-November 2020 among 1,249 GPs in France, 432 GPs in French-speaking parts of Belgium, and 1,055 nurses in Quebec (Canada), all participating in general population immunization. Exploratory and confirmatory factor analyses evaluated the instrument's construct validity. We used HCPs' self-reported vaccine recommendations to patients, general immunization activity, self-vaccination, and future COVID-19 vaccine acceptance to test criterion validity.

RESULTS

The final results indicated a 6-factor structure with good fit: vaccine confidence (combining complacency, perceived vaccine risks, perceived benefit-risk balance, perceived collective responsibility), trust in authorities, perceived constraints, proactive efficacy (combining commitment to vaccination and self-efficacy), reluctant trust, and openness to patients. The instrument showed good convergent and criterion validity and adequate discriminant validity.

CONCLUSIONS

This study found that the Pro-VC-Be is a valid instrument for measuring psychosocial determinants of HCPs' vaccination behaviors in different settings. Its validation is currently underway in Europe among various HCPs in different languages.

'Blurred boundaries': When nurses and midwives give anti-vaccination advice on Facebook

BACKGROUND

Nurses and midwives have a professional obligation to promote health and prevent disease, and therefore they have an essential role to play in vaccination. Despite this, some nurses and midwives have been found to take an anti-vaccination stance and promulgate misinformation about vaccines, often using Facebook as a platform to do so.

RESEARCH QUESTION

This article reports on one component and dataset from a larger study - 'the positives, perils and pitfalls of Facebook for nurses'. It explores the specific issue of nurses and midwives who take an anti-vaccination stance, deemed to be unprofessional by crossing professional boundaries and by providing medical information on Facebook that is not within their scope of practice.

PARTICIPANTS

Data were collected via an online worldwide survey from nurse and midwife participants, distributed and 'snowballed' through relevant nursing and midwifery groups on Facebook. In total, 1644 Registered Nurses and Midwives, and Enrolled Nurses worldwide attempted the online survey. There were 1100 (66.9%) completed surveys and 54 partially (33.1%) completed surveys. Semi-structured interviews were also conducted online using Skype® with 17 participants in Australia.

ETHICAL CONSIDERATIONS

Ethical processes and procedures have been adhered to relating to privacy, confidentiality and anonymity of the participants.

FINDINGS/RESULTS

A mixed-methods approach was used, including descriptive and content analysis of the quantitative survey data and thematic analysis of the qualitative interview data. The main theme 'blurred boundaries' was generated, which comprised three sub-themes: 'follow the science, 'abuse of power and erosion of trust' and 'the moral and ethical responsibility to safeguard public health'. The results offer an important and unique understanding of how nurses and midwives interpret the conduct of fellow health professionals as unprofessional and crossing the professional boundary if they used Facebook to promulgate anti-vaccination messages and/or give medical advice online.

CONCLUSION

There are many positives and negatives for nurses and midwives associated with using Facebook for personal and professional communication, which is in keeping with the results of the larger study from which this article is taken. Professional behaviour is a key theme in the larger research as is the ethical construct of 'every act has a consequence'; however, in this article, the theme 'blurred boundaries' offers an overall understanding of how nurses and midwives interpret the behaviour of their colleagues who espouse anti-vaccination sentiment and/or give medical advice online that is outside their scope of practice and education.

[Influenza vaccine hesitancy among health workers, Bahia State, Brazil]

The World Health Organization acknowledges vaccine hesitancy as one of the ten most serious global health threats. The study investigated the association between confidence, convenience, and complacency and influenza vaccine hesitancy among male and female health workers. The study included 453 workers in primary and medium-complexity health services in a medium-sized city in the state of Bahia, Brazil. Vaccine-hesitant individuals were defined as those who had not received an influenza vaccine in 2019. Structural equation models were used to assess interrelations between target predictive variables and vaccine hesitancy. One-fourth of the workers (25.4%) hesitated to be vaccinated for influenza. Lower confidence (standardized coefficient - SC = 0.261; p = 0.044) and higher complacency (SC = 0.256; p < 0.001) were significantly associated with vaccine hesitancy. Convenience was not associated with vaccine hesitancy. Workers not involved in patient care, workers in medium-complexity services, and male workers reported less receptiveness from the health professional administering the vaccines. Fear of needles was associated with both lower confidence and greater vaccine hesitancy. History of vaccine reactions was not associated directly with vaccine hesitancy, but it was associated with greater complacency, that is, less perception of risk from vaccine-preventable diseases. Since annual influenza vaccination is recommended, influenza vaccine hesitancy can increase the burden of this disease in the population. The data back the hypothesis that factors related to confidence and complacency produce harms in this vaccine´s acceptance and should be considered in the development of strategies and actions for greater adherence to vaccination.

Profiling vaccine believers and skeptics in nurses: A latent profile analysis

BACKGROUND

A tailored immunization program is deemed more successful in encouraging vaccination. Understanding the profiles of vaccine hesitancy constructs in nurses can help policymakers in devising such programs. Encouraging vaccination in nurses is an important step in building public confidence in the upcoming COVID-19 and influenza vaccination campaigns.

OBJECTIVES

Using a person-centered approach, this study aimed to reveal the profiles of the 5C psychological constructs of vaccine hesitancy (confidence, complacency, constraints, calculation, and collective responsibility) among Hong Kong nurses.

DESIGN

Cross-sectional online survey.

SETTINGS

With the promotion of a professional nursing organization, we invited Hong Kong nurses to complete an online survey between mid-March and late April 2020 during the COVID-19 outbreak.

PARTICIPANTS

1,193 eligible nurses (mean age = 40.82, SD = 10.49; with 90.0% being female) were included in the analyses.

METHODS

In the online survey, we asked the invited nurses to report their demographics, COVID-19-related work demands (including the supply of personal protective equipment, work stress, and attitudes towards workplace infection control policies), the 5C vaccine hesitancy components, seasonal influenza vaccine uptake history, and the COVID-19 vaccine uptake intention. Latent profile analysis was employed to identify distinct vaccine hesitancy antecedent subgroups.

RESULTS

Results revealed five profiles, including "believers" (31%; high confidence, collective responsibility; low complacency, constraint), "skeptics" (11%; opposite to the believers), "outsiders" (14%; low calculation, collective responsibility), "contradictors" (4%; high in all 5C constructs), and "middlers" (40%; middle in all 5C constructs). Believers were less educated, reported more long-term illnesses, greater work stress, higher perceived personal protective equipment sufficiency, and stronger trust in government than skeptics. They were older and had higher perceived personal protective equipment sufficiency than middlers. Also, believers were older and had greater work stress than outsiders. From the highest to the lowest on vaccination uptake and intention were believers and contradictors, then middlers and outsiders, and finally skeptics.

CONCLUSION

Different immunization programs can be devised based on the vaccine hesitancy profiles and their predictors. Despite both profiles being low in vaccination uptake and intention, our results distinguished between outsiders and skeptics regarding their different levels of information-seeking engagement. The profile structure reveals the possibilities in devising tailored interventions based on their 5C characteristics. The current data could serve as the reference for the identification of individual profile membership and future profiling studies. Future endeavor is needed to examine the generalizability of the profile structure in other populations and across different study sites. Tweetable abstract: Covid-19 vaccine hesitancy profiles of Hong Kong nurses (believers, sceptics, outsiders, contradictors and middlers) highlight the importance of tailored vaccine campaigns.

Race/Ethnicity Differences in COVID-19 Vaccine Uptake Among Nurses

INTRODUCTION

There is evidence for relatively lower COVID-19 vaccine uptake among people of color in the United States. The purpose of this study was to investigate associations between race/ethnicity and COVID-19 vaccine uptake among nurses.

METHODS

Nurses in Southern California (N = 1183) completed a one-time, web-based survey to assess COVID-19 vaccine perceptions and uptake.

RESULTS

In all, 82.8% of respondents (N = 979) received at least one COVID-19 vaccine dose. Identifying as East Asian was associated with 14% higher odds of COVID-19 vaccine uptake relative to identifying as White (odds ratio [OR] = 1.14/95% confidence interval [CI] = [1.06, 1.24]); identifying as Filipino was associated with 14% higher odds of uptake (OR = 1.14/95% CI = [1.08, 1.20]); and identifying as Hispanic/Latinx was associated with 6% higher odds of uptake (OR = 1.06/95% CI = [1.00, 1.12]).

DISCUSSION

Although nurses and people of color have been identified as groups with low levels of COVID-19 vaccine uptake, this study found that nurses of color received the vaccine at higher levels than their White counterparts.

Acceptance of COVID-19 vaccine and associated factors among health professionals working in Hospitals of South Gondar Zone, Northwest Ethiopia

BACKGROUND

Health-care professions are among the highly exposed group of population affected by COVID-19 pandemic and identified as the target population to get vaccination against the spread of the infection. However, vaccine reluctance is still high, which may negatively affect the efforts to prevent the spread of the infection. Hence, this study was aimed to assess acceptance of COVID-19 vaccine and associated factors among health professionals working in Hospitals of South Gondar Zone, Northwest Ethiopia.

METHODS

Institutional-based cross-sectional study was performed among 422 health professionals working in Hospitals of South Gondar Zone, Northwest Ethiopia, from March 1 to 30, 2021. Study participants were selected through simple random sampling techniques. Data were collected through a self-administered questionnaire. Multivariable logistic regression analysis was performed to identified factors associated with acceptance of COVID-19 vaccine with a p-value < 0.05 at 95% CI considered as statistically significant.

RESULT

Overall, 45.3% of health professionals accepted COVID-19 vaccine. Age (AOR: 2.55; 95% CI: 1.32-4.92), being male (AOR: 1.729; 95% CI: 1.32-2.34), had higher risk of COVID-19 (AOR: 1.74, 95% CI: 1.00-3.02), and positive attitude (AOR: 3.26, 95% CI: 2.14-4.96) were found to be statistically significant with the acceptance of COVID-19 vaccine.

CONCLUSION

The acceptance of COVID-19 vaccine among health professionals was significantly low. Participant's age, sex, high risk of COVID-19, and attitude toward COVID-19 vaccine were significantly associated with vaccine acceptance. Therefore, the government with respective stakeholders should emphasize addressing the concern of the health professionals and increase attitudes regarding COVID-19 vaccine to scale up vaccine acceptance.

Acceptance of COVID-19 vaccines among medical teams in Egypt

Background

Since the start of COVID-19 outbreak investigators are competing to develop and exam vaccines against COVID-19. It would be valuable to protect the population especially health care employees from COVID-19 infection. The success of COVID-19 vaccination programs will rely heavily on public willingness to accept the vaccine.

Aims

This study aimed to describe the existing COVID-19 vaccine approval landscape among the health care providers and to identify the most probable cause of agreement or disagreement of COVID-19 vaccine.

Methods

A cross-sectional online survey was done.

Results

The present study included 496 health care employees, 55% were at age group from 18-45 years old. History of chronic diseases was recorded in 40.4%, and definite history of drug/food allergy in 10.1%. Only 13.5% totally agree to receive the vaccine, 32.4% somewhat agree and 40.9% disagreed to take the vaccine. Causes of disagreement were none safety, fear of genetic mutation and recent techniques and believe that the vaccine is not effective (57%, 20.2%, 17.7% and 16.6% respectively). The most trusted vaccine was the mRNA based vaccine. The age of health care employees and the presence of comorbidities or chronic diseases were the main factors related to COVID-19 acceptance (P<0.001 and 0.02 respectively).

Conclusion

Vaccine hesitancy is not uncommon in healthcare employees in Egypt and this may be an alarming barrier of vaccine acceptance in the rest of population. There is an urgent need to start campaigns to increase the awareness of the vaccine importance.

The Impact of Social Media Exposure and Interpersonal Discussion on Intention of COVID-19 Vaccination among Nurses

COVID-19 vaccine hesitancy among nurses is a global public health concern and it is imperative to understand associated factors. Information environment plays a critical role in shaping health behaviors, while few studies explored such effects in the context of COVID-19 vaccination. A cross-sectional survey was conducted among 1902 nurses in China. The study investigated the effects of social media exposure/interpersonal discussion on intention of COVID-19 vaccination and tested whether perceived effectiveness of COVID-19 vaccines (perceived vaccine efficacy, perceived duration of protection, and perceived effectiveness in preventing resurgences) mediated such associations. Results showed that about 68.0% and 56.5% of the participants had an intention of free and self-paid COVID-19 vaccinations, respectively. Frequent social media exposure and interpersonal discussion were positively associated with vaccination intentions. Perceived vaccine efficacy significantly mediated the effects of frequent social media exposure and interpersonal discussion, whereas perceived effectiveness in preventing resurgences suppressed the effects of frequent social media exposure. In conclusion, the prevalence of intention of COVID-19 vaccination was relatively low among Chinese nurses and health promotion is needed. Frequent social media exposure and interpersonal discussion potentially enhanced vaccination intentions via increased perceived vaccine efficacy. The findings can help inform the development of relevant health communication interventions.

Exploration of the Experience of Care Home Managers of COVID-19 Vaccination Programme Implementation and Uptake by Residents and Staff in Care Homes in Northern Ireland

The Coronavirus 2019 (COVID-19) pandemic disproportionately affected people living and working in care homes. This study aimed to explore the experience of care home managers on the implementation and uptake of the COVID-19 vaccination programme by residents and staff in care homes in Northern Ireland. An exploratory mixed methods approach was used, i.e., semi-structured interviews to design the cross-sectional survey and content analysis of statements using open ended questions. Care home managers were approached and sixty-seven valid quantitative and forty-nine descriptive responses were analysed. The study identified eight themes which described factors that motivated residents (family visits and relationship with managers and staff), and staff vaccine uptake (return to normal life at work and trust in care home managers). The identified themes also confirmed that vaccine uptake is negatively influenced by perceived side effects. The findings indicated that social media can promote or decelerate the uptake of vaccine despite the accessibility to a successful vaccination programme. The study highlights the important role of managers in handling the challenges through building trust and establishing relationships with staff and residents. The findings identified challenges to the uptake of the COVID-19 vaccine by staff and residents that can inform the implementation of future vaccination programmes.

Quality and Safety of Vaccines Manufacturing: An Online Survey on Attitudes and Perceptions of Italian Internet Users

Background: Vaccination is a worldwide public health practice that requires high uptake levels in order to effectively reduce the incidence of vaccine-preventable diseases. The manufacturing of vaccines is a complex process, and little is known about people’s feelings and opinions on that. Our study aimed at investigating perceptions and attitudes of the general population towards the vaccine production process before the availability of COVID-19 vaccines. Methods: We designed a 15-question online survey in the Italian language which was spread via Facebook and an Italian website "Vaccinarsintoscana" between January and May 2020. We performed a descriptive analysis and applied statistical tests to assess differences in the given answers according to participants’ sociodemographic characteristics. Results: The collected responses (135 participants) about the perceptions on vaccine production process were largely positive: not being concerned about the vaccine production (70.3%); believing the vials did not contain harmful substances (75.6%) and considering the precautionary withdrawal of some batches as highly effective (83.7%). In contrast, a less positive perception was found for the question about the conflict of interest between manufacturing companies and the control systems (48.9%). Moreover, people’s perceptions towards the vaccine components (i.e., microorganism, adjuvants and opinion on batches withdrawal) also showed a good level of confidence and trust. Conclusions: Our study highlighted a generally positive attitude towards the vaccine production process and showed people’s confidence in the control systems, safety and high standards of quality of the vaccine production process.

Prenatal care providers' perceptions of the SARS-Cov-2 vaccine for themselves and for pregnant women

BACKGROUND

Prenatal care providers will play an important role in the acceptance of SARS-Cov-2 vaccination for pregnant women.

OBJECTIVE

To determine the perceptions of French prenatal care providers: midwives, general practitioners (GPs) and obstetricians and gynaecologists (Ob-Gyn) regarding SARS-CoV-2 vaccination during pregnancy.

STUDY DESIGN

An anonymous online survey was sent to members of French professional societies representing prenatal practitioners. The participants were asked to answer questions on their characteristics and give their opinions of the SARS-CoV-2 vaccine for themselves and women who are pregnant or willing to become pregnant.

RESULTS

Access to the survey was opened from January 11th, 2021, to March 1st, 2021. A total of 1,416 responses were collected from 749 Ob-Gyn, 598 midwives and 69 GPs. Most respondents (86.7% overall, 90.4% for Ob-GYN, 81.1% for GPs and 80.1% for midwives) agreed to receive the SARS-CoV-2 vaccine. Vaccination against SARS-CoV-2 would be offered to pregnant women by 49.4% 95%CI [48.1-50.8] of the participants. Midwives were less likely to recommend vaccination than GP and Ob-Gyn (37.5%, 50.7% and 58.8%, respectively). The multinomial logistic regression revealed that being an obstetrician, working in a group, usually offering a flu vaccine and wanting to be vaccinated against SARS-CoV-2 were positively associated with considering pregnant women for SARS-CoV-2 vaccination.

CONCLUSION

Most French prenatal healthcare providers are favourable towards vaccinating pregnant women, but a large minority express reservation. More evidence on safety and involvement by professional organisations will be important to encourage the access of pregnant women to vaccination against SARS-CoV-2.

Factors affecting nurses' intention to accept the COVID-19 vaccine: A cross-sectional study

OBJECTIVE

To measure COVID-19 vaccine acceptance and related factors to undercover nurses' concerns and fears.

DESIGN

A cross-sectional study.

SAMPLE

The study included 639 nurses; 83% were women and 80% under 50 years.

MEASUREMENT

A self-administered questionnaire was used. It included demographic characteristics, COVID-19-related fears and concerns, COVID-19 vaccine perceived benefits, and intention toward getting the vaccine.

RESULTS

Forty percent of the nurses planned to get the vaccine when available, 41% would take it later when adequate protection and safety were presented, and 18% would never take it. Significant factors associated with vaccination intention were as follows: age (adjusted OR 1.42, 95% CI: 1.02-1.99); lack of knowledge about the vaccine (adjusted OR 2.6, 95% CI 1.81-3.8); concern about long-term side effects (adjusted OR 2.0, 95% CI 1.4-2.9); fear of injection (adjusted OR 1.5, 95% CI 1.04-2.13); natural immunity preference (adjusted OR 5.8, 95% CI 4.5-8.3); media misrepresentation (adjusted OR 1.7, 95% CI 1.2-2.4); and getting COVID-19 from the vaccine (adjusted OR 1.5, 95% CI 1.1-2.1).

CONCLUSION

COVID-19 vaccine safety and side-effects concerns impact nurses' intentions to accept the vaccine and may result in low acceptance rates. Urgent action is needed to address these fears and raise confidence, as nurses' vaccine-related decisions can affect the public's vaccine acceptance.

A comparative online survey on the intention to get COVID-19 vaccine between Greek and Cypriot healthcare personnel: is the country a predictor?

Vaccine hesitancy amongst healthcare personnel (HCP) is a critical issue. The aim was to explore the factors that determine the intention to opt for COVID-19 vaccine among HCP from two southern European countries. An anonymous online self-administered survey using Google Forms has been conducted between December 1st to December 15th, 2020 among the HCP in Greece and the Republic of Cyprus. A total of 2,238 HCPs participated in the study (1,220/54.5% from Republic of Cyprus and 1,018 from Greece). Overall 1,082 (48.3%) stressed their intention to get vaccinated (64.4% for Greece and 34.9% for Republic of Cyprus). The main reasons for those who intend to get the COVID-19 vaccine include self (94.2%), family (98.7%), and patients protection (95.2%) as well as mitigation of COVID-19 pandemic (95.4%). The multivariate logistic regression that was performed for the total sample revealed that the following variables were significantly associated with an increased probability to get vaccinated against COVID-19: being a physician, a member of the nursing personnel, paramedical staff, working in Greece, age, the belief that influenza vaccination should be mandatory for HCP, and the rating of the overall management of COVID-19 pandemic in the country and from the public hospitals. Physicians were more likely to get vaccinated against COVID-19 than other HCP. The age was a predictor of COVID-19 uptake intention in the Republic of Cyprus. The belief that there was a successful management of the COVID-19 pandemic contributed to the intention to COVID-19 vaccination uptake.

Non-EPI Vaccine Hesitancy among Chinese Adults: A Cross-Sectional Study

Vaccination against coronavirus disease 2019 (COVID-19) is paramount to curtailing the pandemic. However, the impact of the Non-Expanded Program on Immunization (non-EPI) and COVID-19 vaccine hesitancy on vaccine uptake among Chinese adults remain unclear. This study was an online survey performed in Eastern, Central, and Western China between February 2021 and March 2021 using proportional sampling (n = 7381). Adults aged ≥ 18 years were included, especially younger people (aged < 65). Vaccine hesitancy was assessed using the 3C model and relative scales; logistic regression was used to explore the factors affecting vaccination uptake; structural equation modeling was used to evaluate the correlations between variables. Overall, 67.6% and 24.7% of adults reported vaccine hesitancy toward the non-EPI and COVID-19 vaccines, respectively. Participants (66.3%) reported taking the vaccine mainly based on recommendations from medical staff. Vaccine-hesitant participants (60.5%) reported a fear of side effects as the deciding factor in vaccine rejection. Vaccine hesitancy interacted negatively with confidence (β = −0.349, p < 0.001) and convenience (β = −0.232, p < 0.001), and positively with complacence (β = 0.838, p < 0.001). Nonmedical personnel, adults who had previously received the influenza vaccine, and older people had lower vaccine hesitancy than their counterparts. Most Chinese adults have non-EPI but not COVID-19 vaccine hesitancy. Vaccine safety remains a concern.

COVID-19 vaccination intention in the first year of the pandemic: A systematic review

AIMS AND OBJECTIVES

To synthesise evidence regarding vaccination intention, identify factors contributing to vaccine hesitancy among healthcare professionals and the general populations globally.

BACKGROUND

As COVID-19 vaccine becomes available worldwide, attention is being directed to community vaccine uptake, to achieve population-wide immunity. A number of factors have been reported to influence vaccine intention.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic search of COVID-19 vaccination intention related literature published on or before 31 December 2020 from seven databases was undertaken.

RESULTS

Thirty articles were included in this systematic review. Overall COVID-19 vaccination intention during the first year of the pandemic ranged from 27.7% to 93.3%. Findings highlighted that socio-demographic differences, perceptions of risk and susceptibility to COVID-19 and vaccine attributes influenced vaccination intention. Healthcare professionals particularly, nurses have higher vaccine hesitancy reportedly due to concerns regarding vaccine safety and efficacy and mistrust of health authorities. Negative information about COVID-19 vaccines in the social media and low confidence in the health system were associated with lower acceptability among the community. Interestingly, cumulative increase in COVID-19 caseloads of countries over time was not associated with vaccination intention.

CONCLUSIONS

The significant variability in vaccine intention rates worldwide would hamper efforts to achieve immunity against COVID-19. Nurses' concerns about vaccine safety and efficacy need to be addressed to increase vaccine acceptance and maximise their influence on vaccination decision in the community. As misinformation through social media negatively impacts vaccination uptake, authoritative and reliable information on vaccine attributes, disease risks and vaccination benefits are needed.

RELEVANCE TO CLINICAL PRACTICE

Concerns about vaccine safety and efficacy including misinformation are important contributors to vaccine hesitancy. Addressing these factors, particularly among nurses who are considered trusted influencers of vaccination decisions in the community is an important strategy for pandemic preparedness.

A brief educational intervention can improve nursing students' knowledge of the human papillomavirus vaccine and readiness to counsel

Provider recommendation is a primary reason for patient uptake of the human papillomavirus (HPV) vaccine. Most provider-focused educational interventions are focused on physicians, even though nurses are also important sources of vaccine-related information for their patients. This study examined whether a HPV educational intervention could improve nursing students' HPV knowledge, beliefs, and comfort with counseling. The same lecture on HPV and HPV vaccination was given to both medical and nursing students. To determine the effects of the lecture, students were asked to complete identical pre- and post-lecture tests with questions on demographics, knowledge, attitudes, and comfort with counseling on the HPV vaccine. Pre- and post-lecture test scores were compared between nursing and medical students to assess whether there were differences in pre-lecture test scores and/or changes in post-lecture test scores. On the pre-lecture tests, fewer nursing students responded correctly to knowledge questions, indicated positive attitudes or comfort with counseling about the HPV vaccine compared to medical students. However, similar frequencies of nursing and medical students responded correctly to knowledge questions and indicated a positive attitude, as well as a high comfort level with counseling on the post-lecture tests. Study results show that integrating lectures in a nursing program curriculum could be a feasible way to increase students' HPV knowledge. Having health-care providers with similar levels of knowledge, attitudes, and comfort with counseling on HPV vaccination is ideal, as all share the responsibility of recommending the vaccine to patients.

Vaccine hesitancy among hospital staff physicians: A cross-sectional survey in France in 2019

BACKGROUND

Healthcare professionals, because they recommend vaccines to their patients, answer their questions, and vaccinate them, are the cornerstone of vaccination in France. They can nonetheless be affected by vaccine hesitancy (VH).

AIMS

We sought to study the opinions, practices, and perceptions of French hospital staff physicians (HSPs) toward vaccination and the prevalence and correlates of VH among them.

METHODS

We conducted a cross-sectional survey in 14 public hospitals in France from September 2018 to October 2019. HSPs completed a standardized questionnaire -most of the time face-to-face - about their vaccine-related attitudes and practices. Data were weighted for age and sex. An agglomerative hierarchical cluster analysis of the HSPs' perceptions and opinions toward vaccination allowed us to identify vaccine-hesitant HSPs, and multiple Poisson regression with robust standard errors let us study the factors associated with VH.

RESULTS

The study included 1,795 HSPs (participation rate: 86%). Almost all (93.7%) were strongly favorable to vaccination, even though 42.2% (95CI = 39.8-44.6) showed moderate VH. VH prevalence was lowest among infectious disease specialists (12.3%; 95CI = 6.7-21.3) and pediatricians (27.7%; 95CI = 21.4-35.2). Hesitant HSPs were less trustful of vaccination information sources and doubted the safety of vaccines more often than HSPs with almost no VH. Compared with non-hesitant HSPs, those with higher VH had less often taken a medical course about vaccination and were less likely to be vaccinated against seasonal influenza, to recommend vaccines to their patients and to try to convince vaccine-hesitant patients to be vaccinated.

CONCLUSIONS

Strong favorability to vaccination does not prevent VH, which was observed in most specialties. Interventions are required to help hesitant HSPs to adopt more proactive vaccination practices.

Attitudes and Acceptance of COVID-19 Vaccination Among Nurses and Midwives in Cyprus: A Cross-Sectional Survey

Healthcare workers are at the frontline of the COVID-19 pandemic and have been identified as a priority target group for COVID-19 vaccines. This study aimed to determine the COVID-19 vaccination intention among nurses and midwives in Cyprus and reveal the influential factors that affected their decision. An Internet-based cross-sectional survey was conducted between December 8 and 28, 2020. Data collection was accomplished using a self-administered questionnaire with questions about socio-demographic characteristics, questions assessing general vaccination-related intentions and behaviors, and the intention to accept COVID-19 vaccination. A sample of 437 responders answered the survey, with 93% being nurses and 7% midwives. A small proportion of the participants would accept a vaccine against COVID-19, while 70% could be qualified as "vaccine hesitant." The main reasons for not receiving the COVID-19 vaccine were concerns about the vaccine's expedited development and fear of side effects. More females, individuals with a larger median age, and a higher number of years of working experience, intended to accept the COVID-19 vaccination, compared with those not intended to accept and undecided groups (p < 0.01). Having a seasonal flu vaccination in the last 5 years, receiving the vaccines recommended for health professionals, and working in the private sector were associated with a higher probability of COVID-19 vaccination acceptance. A considerable rate of nurses and midwives in Cyprus reported unwillingness to receive a COVID-19 vaccine due to vaccine-related concerns. Our findings highlight the need for forthcoming vaccination campaigns and programs to tackle coronavirus vaccine hesitancy barriers to achieve the desirable vaccination coverage.

Vaccine Hesitancy: COVID-19 and Influenza Vaccine Willingness among Parents in Wuxi, China-A Cross-Sectional Study

Objectives: We aimed to (1) assess parental hesitancy about category A (Expanded Program on Immunization (EPI)) and B (non-EPI) vaccines, (2) assess parental willingness for COVID-19 and influenza vaccinations, and (3) explore the association of vaccination hesitancy of parents and healthcare workers (HCWs). Methods: The study was performed in Wuxi, eastern China between 21 September 2020 and 17 October 2020. Parents of children aged <18 years and HCWs were recruited from the selected immunization clinics. Vaccine hesitancy was assessed using the Strategic Advisory Group of Experts (SAGE) vaccine hesitancy survey (VHS) by summing the total score for 10 items (maximum 50 points). Results: A total of 3009 parents and 86 HCWs were included in the analysis. The category A VHS scores were significantly higher than the category B VHS scores (p = 0.000). Overall, 59.3% and 52.4% of parents reported willingness to avail COVID-19 and influenza vaccination for their children, respectively; 51.2% of the HCWs wanted to be vaccinated against COVID-19. Parental category B VHS scores were associated with HCW category B VHS scores (r = 0.928, p = 0.008). Conclusions: In China, parents are more hesitant about category B vaccines than category A vaccines. More than 40% of parents showed hesitancy and a refusal to use COVID-19 and influenza vaccines.

Attitudes of hospital physicians toward childhood mandatory vaccines in France: A cross-sectional survey

Background

Due to a decades-long crisis of confidence in vaccination, in 2017 France extended the number of mandatory early childhood vaccines from 3 to 11.

Aims

To describe the opinions of hospital staff physicians (HSPs) regarding this measure, quantify the proportion who would have preferred measures based on education, and study the factors associated with the latter opinion.

Methods

Cross-sectional nationwide survey with a standardized questionnaire in 2018–2019 among HSPs in 14 French public hospitals. The factors associated with HSPs’ preference for education and persuasion over mandatory vaccination were analyzed with simple and multiple Poisson regressions.

Results

The analyses included 1,795 HSPs (participation rate of 86%). Among them, 84% considered the extension of mandatory childhood vaccination essential given the epidemiological context at the time; in a later question, 40% would have preferred education and persuasion. Multiple regressions showed that the latter tended to be younger and less trustful of sources of information about vaccination. They were more likely to think that information on the rationale behind the national vaccination policy lacked clarity and that the extension of mandatory vaccines was not essential, even in the current epidemiologic situation.

Conclusion

Although most HSPs agreed that the extension of mandatory childhood vaccines was essential, some were ambivalent about its coercive philosophy. Further research is necessary to better understand the reasons of this ambivalence. A fraction did not understand the French vaccination strategy well. Efforts to explain its details to HSPs and an overhaul of their initial training on vaccination are still needed.

Vaccine Hesitancy among Italian Patients Recovered from COVID-19 Infection towards Influenza and Sars-Cov-2 Vaccination

We aimed to assess the attitude towards influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations among coronavirus disease 2019 (COVID-19) recovered patients. We performed a cross-sectional study consisting of a standardized telephone interview carried out between September and November 2020 targeting a cohort of adult in- and out-patients that had recovered from COVID-19 after the first wave (March-May 2020) at Udine Hospital (Italy). Overall, 599 people participated (320 female, median age 53 years) and most had experienced an acute COVID-19 with mild illness (409, 68.3%). The majority were hesitant or undecided towards influenza (327, 54.6%) and SARS-CoV-2 (353, 59.2%) vaccines. Older age, public work exposure, and previous 2019 flu shots were the main factors associated with a positive attitude toward both vaccinations (p < 0.05). Being hospitalized during the acute COVID-19 phase was associated with the willingness to get a flu shot (94/272, 34.5%) but not SARS-CoV-2 vaccine (70/244, 28.7%). Vaccine hesitancy is diffuse and multifactorial also among COVID-19 recovered.
