Wang X, Liu M, Li Y, Mei X, Liao S, Liang Q, Liu Y. What determinants of COVID-19 vaccine hesitancy among Chinese nursing students? A cross-sectional study. Front Public Health 2024; 12:1432225. [PMID: 39228852 PMCID: PMC11368718 DOI: 10.3389/fpubh.2024.1432225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Accepted: 08/05/2024] [Indexed: 09/05/2024] Open
Abstract
Background The coronavirus disease 2019 (COVID-19) continues to threaten human health, and health professionals, including nursing students, usually work in healthcare frontiers with a high risk of infection. Vaccination is currently one of the most effective preventive measures. This study aimed to explore the determinants of COVID-19 vaccine hesitancy in nursing students. Methods In November 2022, a sample of undergraduate nursing students was recruited from several medical schools in Anhui Province, China, and an online cross-sectional survey was conducted using the questionnaire star platform (Wenjuanxin). A Chi-square test was used to explore vaccine hesitancy among nursing students with different social demographic characteristics and vaccine attitudes. Binary logistic regression analysis was then used to determine the influence factors of vaccine hesitancy among nursing students. Results A total of 1,090 valid samples were collected in this study. Of these, 27.06% (295) of nursing students reported COVID-19 vaccine hesitancy. The results showed "the need to go out of town recently" (OR = 0.670), "very confident that the outbreak could be controlled sustainably" (OR = 0.393), "feeling at risk of infection" (OR = 0.658), "not being worried/being generally worried about the vaccine's safety" (OR = 0.226 and OR = 0.686, respectively), and "not being worried about the vaccine's effectiveness" (OR = 0.411). These five factors are protective factors associated with COVID-19 vaccine hesitancy in nursing students. The factors "considering the country completely safe from an outbreak" (OR = 3.436), "considering themselves safe because others are vaccinated" (OR = 2.239), and "Agreeing that other protective measures can be relaxed after vaccination with the COVID-19 vaccine" (OR = 2.007) are risk factors associated with COVID-19 vaccine hesitancy among nursing students (P < 0.05). Conclusion Overall, relatively few nursing students had COVID-19 vaccine hesitancy. Schools and relevant institutions still need to actively guide them to improve their confidence in the COVID-19 vaccine, strengthen the prevention and control measures of the epidemic, and improve their awareness of the crisis to improve the vaccination rate to reduce the COVID-19 vaccine hesitancy in nursing students.

Abstract
BACKGROUND Vaccination is the most important public health practice for preventing infectious diseases and maintaining health. However, some parents are hesitant to vaccinate their children. DESIGN This study was designed as an instrument development study. METHODS This study aimed to develop a scale to measure the attitudes of parents with children aged 0-5 years towards vaccination and to evaluate the validity and reliability of this scale. The data were collected from 691 participants between November 2020 and January 2021. During the development of the scale, experts provided feedback on its technical, content and language dimensions. The data were analysed using exploratory and confirmatory factor analyses for conceptual validity and Cronbach's α and item-level test-retest analyses for reliability. RESULTS The developed scale is a reliable and valid tool for measuring attitudes towards vaccination among parents (Cronbach's α = 0.97, variance explained by these 28-item two factors = 62.47%). CONCLUSION This scale can be used as a guide in measuring the attitudes of parents towards vaccination and determining the direction of primary health-care services based on the results of the measurement.

Abstract
BACKGROUND African Americans (AAs) are disproportionately affected by structural and social determinants of health, resulting in greater risks of exposure to and deaths from COVID-19. Structural and social determinants of health feed vaccine hesitancy and worsen health disparities. OBJECTIVE The present study aims to explore vaccine attitudes and intentions among program participants, understand the role of an African American faith-based wellness program in COVID-19 awareness and vaccine uptake, and solicit potential solutions for this deep-rooted public health problem. METHODS Data were collected through 21 in-depth interviews among individuals involved within a community-based wellness program. Sixteen phone and five in-person interviews were conducted with church leaders, lifestyle coaches, and program participants. All interviews were audio-recorded, transcribed verbatim, and inductively and thematically analyzed by three researchers. FINDINGS Live Well by Faith (LWBF) acted as a trusted information source for COVID-19 resources for the AA community. Services provided by Live Well by Faith included enrolling community members for vaccines, negotiating vaccine provision to and facilitating the establishment of vaccine clinics at AA churches, and connecting community members to healthcare providers. Despite the role Live Well by Faith played, VH was a significant concern due, in part, to historical mistrust of government and pharmaceutical companies conducting unethical healthcare research among Black populations. Other factors included uncertainty about vaccination (vaccines' safety, efficacy, and necessity), social media misinformation, and political affiliation. Participants expressed the need for government to commit resources towards addressing historical factors and building trust with minority populations. CONCLUSION Resource targeting programs such as Live Well by Faith that engage faith and community leaders in co-designed shared and culturally grounded interventions can help restore and strengthen trust in vaccines and governments and reduce vaccine hesitancy.

Abstract
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.

Abstract
BACKGROUND In 2016-18, a large measles outbreak occurred in Romania identified by pockets of sub-optimally vaccinated population groups in the country. The aim of the current study was to gain insight into barriers and drivers from the experience of measles vaccination from the perspectives of caregivers and their providers. METHODS Data were collected by non-participant observation of vaccination consultations and individual interviews with health workers and caregivers in eight Romanian clinics with high or low measles vaccination uptake. Romanian stakeholders were involved in all steps of the study. The findings of this study were discussed during a workshop with key stakeholders. RESULTS Over 400 h of observation and 161 interviews were conducted. A clear difference was found between clinics with high and low measles vaccination uptake which indicates that being aware of and following recommended practices for both vaccination service delivery and conveying vaccine recommendations to caregivers may have an impact on vaccine uptake. Barriers identified were related to shortcomings in following recommended practices for vaccination consultations by health workers (e.g. correctly assessing contraindications or providing enough information to allow an informed decision). These observations were largely confirmed in interviews with caregivers and revealed significant knowledge gaps. CONCLUSIONS The identification of key barriers provided an opportunity to design specific interventions to improve vaccination service delivery (e.g. mobile vaccination clinics, use of an electronic vaccination registry system for scheduling of appointments) and build capacity among health workers (e.g. guidance and supporting materials and training programmes).

The Multidimensional Vaccine Hesitancy Scale: A Validation Study. Vaccines (Basel) 2022; 10:vaccines10101755.

Abstract
Vaccination hesitancy (VH) is a phenomenon which increases the occurrence of vaccine-preventable diseases. The study tests the validity of the Multidimensional Vaccine Hesitancy Scale (MVHS) in the case of a sample of Romanian adults (n = 528; Meanage = 30.57). The latter filled in an online cross-sectional survey. The construct validity of MVHS was assessed by using confirmatory factor analysis (CFA), the reliability was calculated by using the internal consistency, and the convergent and discriminant validity was assessed by using the composite reliability (CR), and average variance extracted (AVE). The obtained model was invariant across gender. The structural equation model was designed for predictive validity by using the partial least square method (PLS-SEM) which analyses the relation between the MVHS dimensions and the vaccination willingness. The results show support for the 8-factor structure of the scale (χ2/df = 2.48; CFI = 0.95; RMSEA = 0.053). The Cronbach’s coefficients α > 0.70; McDonald’s ω > 0.70 and CR > 0.80 have very good values. The structural equation model shows that there are more dimensions of the scale which predict vaccination hesitancy in various types of vaccines—the main predictors remain the dimensions of health risk and healthy condition. The study’s conclusion led to the idea that the MVHS is suitable for medical practice and for research on the analysis of vaccination behaviours and intentions.

Abstract
This paper is an evaluation of seasonal influenza vaccination hesitancy (IVH) and its determinants among community HCWs in Chongqing, a city in southwest China. Methods: A cross-sectional survey of 1030 community HCWs with direct or indirect patient contact was conducted from July to September 2021 using a self-administered electronic questionnaire. Possible factors for IVH among community HCWs were investigated by multivariable logistic regression to yield adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Results: Overall, 46.2% of community HCWs were vaccinated in the 2020–2021 season, while 65.8% of community HCWs had IVH. “Don’t know the coverage in China” (OR: 1.46, 95% CI: 1.01–2.11; 40-year-old group OR: 3.02, 95% CI: 1.92–4.76), “complacency” (OR: 4.55, 95% CI: 3.14–6.60) were positively related with having IVH. The community HCWs that had a history of influenza vaccination (OR: 0.67 95% CI: 0.48–0.95) and groups with confidence and convenience (OR: 0.08, 95% CI: 0.06–0.12; OR: 0.34, 95% CI: 0.23–0.52, respectively) were more likely to completely accept vaccination. Conclusions: Measures such as improving the awareness and knowledge of influenza and vaccination and expanding the free vaccination policy, combined with improving the convenience of the vaccination service, will promote increased seasonal influenza vaccination-coverage in community HCWs in Chongqing.

Abstract
Background: According to WHO, infectious disease control can be achieved if the vaccine coverage (VC) exceeds 90%. In recent years there has been a declining trend in VC which could lead to the recurrence of infectious diseases. Objectives: The study analyzed the determinants of VC and of parental decisions regarding immunization in children aged 0−1 year monitored during two high-risk epidemiological periods (the measles epidemic and the COVID-19 pandemic period). Methods: A retrospective observational cohort study-data regarding vaccination of children younger than 1 year of age during the periods January 2019−June 2019 (measles epidemic) and January 2020−June 2020 (COVID-19 pandemic) were analyzed. 2.850 children from 2019 and 2.823 children from 2020 were enrolled. Family physicians interacted with 2840 parents or legal guardians in 2019 and with 2800 parents or legal guardians in 2020, during the infants’ consults providing medical information and answer to their questions and worries regarding their immunization. Data on immunization schedules on the determinants of parents’ decisions regarding vaccination were evaluated. Results: During 2019−2020, VC has followed a declining trend for each type of vaccine included in the Romanian National Immunization Program; the most affected were infants aged 9−12 months during both periods: in 9-month aged infants, the MMR vaccine VC was 67.49% in 2019 vs. 59.04% in 2020 (p < 0.004). In the 12 months aged infants, the MMR VC was 64.29% in 2019 vs. 55.88% in 2020 (p < 0.005). For the Hexavalent vaccine administered at the age of 11 months, the VC was 71.59% in 2019 vs. 62.08% in 2020 (p < 0.001). The determinants of parents’ decisions regarding vaccination included parental hesitance 2019—25% vs. 2020—35%, fear on side effects 2019—32% vs. 2020—45%, vaccination denial 2019—7% vs. 2020—10%. Conclusion: We found a declining trend in the VC in Romania during the epidemic and pandemic periods. The decrease in VC for MMR generated a major risk for new measles outbreaks Permanent awareness educational campaigns regarding infectious disease risk are needed, accompanied by the empowerment of primary care and the emergence of an immunization management program based on national regulatory legislation.

Reasons and suggestions for improving low immunization uptake among children living in low socioeconomic status communities in Northern Alberta, Canada - A qualitative study. Vaccine 2022; 40:4464-4472.

Abstract
OBJECTIVE Under-immunization increases the risk of acquiring vaccine-preventable diseases in children and the community. The targeted coverage rate for routine childhood immunization in Alberta, especially in disadvantaged communities in rural and remote geographic areas, has not been achieved for many years. This study was conducted to identify reasons for under-immunization in children in low socioeconomic status (SES) communities and propose suggestions to address issues/concerns identified by low SES parents for improving immunization coverage in their communities. METHODS Fourteen semi-structured phone interviews of low SES parents with under-immunized children living in rural and remote geographic areas in Northern Alberta were conducted. Transcripts were analyzed to identify relevant themes. RESULTS Busy lifestyles of many parents prevented them from taking their children to clinics for immunization, which were exacerbated by long distances to clinics, transportation issues, operating hours of clinics, and lack of reminders. Many disadvantaged parents also exhibited varying levels of vaccine hesitancy due to safety concerns, especially about newer vaccines, thereby causing some parents to delay immunizing their child intentionally. CONCLUSION Implementing procedures to alleviate access issues, such as offering extended operating hours, opening drop-in clinics/satellite clinics in distant areas, nurse visits to their homes, updating contact information of parents, frequent reminder options and addressing safety and effectiveness concerns about vaccines in plain language using evidence-based communication strategies can promote timely immunization among children of low SES parents.

Abstract
Vaccination is one of the most useful medical interventions for controlling certain infectious diseases. The aim of current research is to identify some of the drivers of vaccine hesitancy or acceptance in a rather skeptical European population by addressing parental perception on optional vaccination (OV) perception. Novel tools, delivered by social media, were used in our research attempt. A validated questionnaire was distributed online among parents. Parental knowledge, attitudes and perceptions of OV were analyzed. The majority of parent respondents (55.1%) showed very good knowledge about vaccination and vaccine-preventable diseases, and 76.0% stated that they had given at least one optional vaccine to at least one of their children. The most common optional vaccine administered was the rotavirus vaccine. The level of knowledge appeared to be related to compliance with OV. Concurrently, the rate of vaccine acceptance in the NIP (National Immunization Program) was not correlated with the level of parental knowledge. In total, a high percentage of parents (77.6%) believed that OV can bring an additional health safety benefit to their children. This study shows the need to involve the medical community in a steady dialogue with parents about OV. Raising awareness by presenting clear and understandable information could be a game-changing intervention in mitigating the public health impact of OV-preventable diseases.

Abstract
Developing and implementing new immunization policies in response to shifting epidemiology is a critical public health component. We adopted a mixed-methods approach (via narrative literature review [101 articles] and 9 semi-structured interviews) to evaluate policy development in response to shifting measles epidemiology in six European countries (Italy, Belgium, Germany, Romania, UK, and Ukraine); where policies and strategies have evolved in response to country-specific disease and vaccination patterns. Periodic outbreaks have occurred in all countries against a background of declining measles-containing-vaccine (MCV) uptake and increasing public vaccine hesitancy (with substantial regional or social differences in measles burden and vaccine uptake). Health-care worker (HCW) vaccine skepticism is also seen. While many outbreaks arise or involve specific susceptible populations (e.g., minority/migrant communities), the broader pattern is spread to the wider (and generally older) population; often among incompletely/non-vaccinated individuals as a legacy of previous low uptake. Immunization policy and strategic responses are influenced by political and social factors, where public mistrust contributes to vaccine hesitancy. A strong centralized immunization framework (allied with effective regional implementation and coherent political commitment) can effectively increase uptake. Mandatory vaccination has increased childhood MCV uptake in Italy, and similar benefits could be anticipated for other countries considering vaccine mandates. Although possible elsewhere, socio-political considerations render mandating impractical in other countries, where targeted immunization activities to bolster routine uptake are more important. Addressing HCW skepticism, knowledge gaps, improving access and increasing public/community engagement and education to address vaccine hesitancy/mistrust (especially in communities with specific unmet needs) is critical.

Abstract
Public health measures remain the best available approach to tackle the coronavirus disease 2019 (COVID-19) pandemic. However, little is currently known about the compliance and acceptance of these measures by people in India. The Department of Community Medicine at Vardhman Mahavir Medical College (VMMC), and Safdarjung Hospital, a tertiary care hospital in New Delhi, organized a health education campaign for raising awareness on COVID-19 in the hospital premises over a period of 15 d in May 2021. Educational and interactive sessions were conducted by medical residents, interns, and staff. Data on compliance to public health measures were collected and analyzed using SPSS 21. All quantitative variables were descriptively analyzed while qualitative data were narratively analyzed. A total of 84 (12.57%) of those observed were wearing their mask incorrectly. Social distancing was inadequate at 16 sites. Sixty-nine (10.33%) reported to have received single or both doses of vaccine. Common reasons for not getting vaccinated included doubts about vaccine efficacy, eligibility, adverse events, availability, and accessibility. Mask use was universal, but directives on correct protocol of wearing masks needs to be widely circulated. Credible information about vaccine safety, efficacy, availability, and accessibility needs to be available to the community to build confidence in COVID-19 vaccination.

Universal Predictors of Dental Students' Attitudes towards COVID-19 Vaccination: Machine Learning-Based Approach. Vaccines (Basel) 2021; 9:1158. [PMID: 34696266 PMCID: PMC8539257 DOI: 10.3390/vaccines9101158] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 10/01/2021] [Accepted: 10/08/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND young adults represent a critical target for mass-vaccination strategies of COVID-19 that aim to achieve herd immunity. Healthcare students, including dental students, are perceived as the upper echelon of health literacy; therefore, their health-related beliefs, attitudes and behaviors influence their peers and communities. The main aim of this study was to synthesize a data-driven model for the predictors of COVID-19 vaccine willingness among dental students. METHODS a secondary analysis of data extracted from a recently conducted multi-center and multi-national cross-sectional study of dental students' attitudes towards COVID-19 vaccination in 22 countries was carried out utilizing decision tree and regression analyses. Based on previous literature, a proposed conceptual model was developed and tested through a machine learning approach to elicit factors related to dental students' willingness to get the COVID-19 vaccine. RESULTS machine learning analysis suggested five important predictors of COVID-19 vaccination willingness among dental students globally, i.e., the economic level of the country where the student lives and studies, the individual's trust of the pharmaceutical industry, the individual's misconception of natural immunity, the individual's belief of vaccines risk-benefit-ratio, and the individual's attitudes toward novel vaccines. CONCLUSIONS according to the socio-ecological theory, the country's economic level was the only contextual predictor, while the rest were individual predictors. Future research is recommended to be designed in a longitudinal fashion to facilitate evaluating the proposed model. The interventions of controlling vaccine hesitancy among the youth population may benefit from improving their views of the risk-benefit ratio of COVID-19 vaccines. Moreover, healthcare students, including dental students, will likely benefit from increasing their awareness of immunization and infectious diseases through curricular amendments.

Abstract
Vaccine hesitancy seriously hinders herd immunity. We explored the determinants of parental hesitancy to vaccinate children against Coronavirus Disease 2019 (COVID-19) in China.A population-based self-administered online questionnaire evaluating parental hesitancy in vaccinating their children against COVID-19 was conducted in Taizhou, China. Of the 2463 parents who received the invitation, 1788 (72.6%) responded to the survey.Of the repondents, 52.5% were hesitant. Mothers exhibited a greater proportion of vaccine hesitancy than fathers did (57.5% vs. 41.7%, P < 0.001). Multiple logistic regression analysis indicated that parents with children under 18 years of age (OR = 0.94, 95%CI: 0.90-0.99), lower knowledge scores about COVID-19 vaccination (Q1: OR = 1.92, 95%CI: 1.37-2.69; Q2: OR = 1.51, 95%CI: 1.10-2.08), lower awareness of the permission of vaccinating children (OR = 1.74, 95%CI: 1.36-2.23) and hesitancy to inoculate themselves (OR = 8.18, 95%CI: 6.48-10.33) were associated with parental hesitancy to inoculate their children. Results also revealed the disparity between fathers and mothers regarding associated factors.This study found that a substantial proportion of parents reported being hesitant to vaccinate children against COVID-19, implying the necessity of comprehensive assessment and health education programs for vaccination systems in China.

Abstract
In Romania, the first phase of the COVID-19 vaccination campaign prioritized medical personnel, which included healthcare students. This study aimed to assess their knowledge, attitudes towards, and perception of COVID-19 vaccination. An anonymous, single-answer, 42-item online survey was conducted from 12 January until 3 March 2021, in the country’s largest University of Medicine and Pharmacy. Among the 1581 respondents (14.9% response rate), 88.5% were pro-vaccination, 7.8% were undecided, and 3.7% were vaccine resistant. The main reason for vaccine rejection was the perceived speed of vaccine development (strong agreement among the vaccine resistant, moderate agreement among the undecided, p < 0.001). Concern over long-term adverse reaction was present in only 11.5% of the respondents, significantly more frequent in the undecided and vaccine resistant. Perceived knowledge on the vaccines’ safety, efficacy, and technology correlated with a pro-vaccine attitude (p < 0.001). Most respondents had a positive stance towards vaccination in general, influencing their behaviour as future parents (99.3% of the pro-vaccination, 95.1% of the undecided, and 89.1% of the vaccine resistant will vaccinate their children, p < 0.001) and as medical professionals (99.7% of the pro-vaccination, 93.5% of those undecided, and 89.8% of the vaccine resistant would advise parents to vaccinate their children, p < 0.001). Healthcare students can thus serve as important vectors for scientifically sound information, influencing vaccine uptake in the community.

Abstract
Aim Relations between penal responsibility and vaccination obligation can be essential for raising the vaccination rate. Social media play a vital role in distributing information. The attitude towards vaccination consists of many factors, including the criminal law situation in the field of vaccination in a given country. The aim of the study was to assess the impact of criminal law liability and other social factors such as age and education on mothers’ desire to vaccinate their children. Methods Survey target: mothers from nine European countries (Poland, Germany, Slovakia, France, Norway, Serbia, Romania, Greece, Italy). Response count: 2205. Questionnaire content: adjusted to country-specific legal regulations concerning vaccinations - considering whether vaccines are mandatory, recommended, additional, and how to cover costs. The way of dissemination of the questionnaire: general parental groups on Facebook. Results The respondents: Poles (30%), Italians, Germans, Slovaks, Greeks (10% each), Norwegians, Frenchwomen, Romanians, Serbians (5% each). The average respondent age: highest: Norway (38.14±10.08) and Italy (37.35±8.12), lowest: Slovakia (30.22±6.19). Respondents with higher, secondary, vocational, primary education represent 58%, 27%, 12%, 3%, respectively, of the group. Countries with above 90% rate of answers that they vaccinate their children: Greece, Norway, Slovakia, France. The lowest rate (55%) recorded for Romania. Sixty-seven percent aware of the existence of anti-vaccination movements. High rates were recorded for Norway (88%), Romania (82%), Poland (78%), Serbia (71%), Greece (67%), Germany (66%). The lowest rate for France (31%). Countries without vaccination at all (Germany, Norway, Romania, Greece), the rest of the countries mentioned above – have some mandatory, recommended and additional vaccinations. Conclusion In countries with mandatory vaccinations parents have their children vaccinated less willingly than in countries with voluntary vaccinations. The rising level of education and providing information about complications following infectious diseases appear to increase the vaccination rate.

A validated modification of the vaccine hesitancy scale for childhood, influenza and HPV vaccines. Vaccine 2021; 39:1831-1839.

Abstract
INTRODUCTION Vaccine hesitancy contributes to outbreaks of preventable disease worldwide. The Vaccine Hesitancy Scale (VHS), developed by the international WHO SAGE Working Group, has been validated previously for measuring hesitancy towards childhood vaccines; some psychometric properties were suboptimal. METHODS We collected data using large, nationally-representative samples of parents in the U.S. We adapted the VHS items, and additional hesitancy items, to assess hesitancy towards influenza and HPV vaccines in addition to routine childhood vaccines. We then used exploratory and confirmatory factor analysis to identify latent constructs and create modified scales for childhood (VHS-child), influenza (VHS-flu) and HPV (VHS-HPV) vaccines with improved psychometric properties. Finally, we compared hesitancy scores on the VHS-child, VHS-flu, and VHS-HPV, to self-reported receipt of each vaccine category, and compared subscale scores to assess whether drivers of hesitancy differed by vaccine category. RESULTS 2052 parents of children <18 years old completed the VHS-child and VHS-flu while 2020 parents of adolescents completed the VHS-HPV. A two-factor structure of 'risks' and a 'lack of confidence' was found for each vaccine category. Slight modifications to the VHS improved psychometric properties. Hesitancy was strongly associated with vaccine receipt: e.g., 76% of parents not hesitant towards influenza vaccine had vaccinated their child the past season, versus 9% of hesitant parents (p < 0.0001). Subscale scores also differed significantly between vaccines: lack of confidence was greater towards influenza (Median (IQR): 2.0 (1.2, 3.3)) and HPV (2.0 (1.3, 3.0)) vaccines than childhood (1.2 (1.0, 1.8), p < 0.0001 for both) vaccines; perceived risks of HPV vaccines (2.7 (1.7, 3.7)) were greater than for childhood vaccines (2.0 (1.3, 3.0), p < 0.0001). CONCLUSIONS Our modified VHS scales perform well psychometrically and allow for consistent measurement of the extent and reasons for hesitancy between vaccine categories. We suggest that future work use these scales to examine hesitancy towards other vaccines and to monitor hesitancy over time.

Abstract
Since the outbreak of COVID-19 in December 2019, no global consensus treatment has been developed and generally accepted for the disease. However, eradicating the disease will require a safe and efficacious vaccine. In order to prepare for the eventual development of a safe and efficacious COVID-19 vaccine and to enhance its uptake, it is imperative to assess vaccine hesitancy in Cameroonians. After obtaining ethical clearance from the Institutional Review Board of the University of Buea, a questionnaire was administered (May–August 2020) to consenting adults either online or in person. A qualitative thematic analysis was done to analyze the participants’ answers to the open questions. A deductive approach was used, that is, the codes and patterns according to the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) Working Group Matrix of Determinants of vaccine hesitancy. The number of consenting adult Cameroonians who completed the questionnaire were 2512 (Two thousand five hundred and twelve). Vaccine hesitancy to a COVID-19 vaccine was 84.6% in Cameroonians. Using the WHO recommended Matrix of Determinant of Vaccine hesitancy, the most prominent determinants observed in this study were: Communication and Media Environment, Perception of pharmaceutical industry, Reliability and/or source of vaccine and cost. Most Cameroonians agree that even though there are benefits of a clinical trial, they will prefer it should be done out of the continent and involving African scientists for eventual acceptance and uptake. The concerns of safety, efficacy and confidence has to be addressed using a Public Engagement approach if a COVID-19 vaccine has to be administered successfully in Africa or Cameroon specifically. Since this study was carried out following WHO standards, its result can be compared to those of other studies carried out in different cultural settings using similar standards.

Abstract
OBJECTIVE To determine the vaccination refusal rate, associated factors and perceptions of parents who refused routine immunization for their children using the World Health Organization (WHO) SAGE Working Group on Vaccine Hesitancy Survey Tool. MATERIALS AND METHODS A cross-sectional survey was conducted using multi-stage cluster sampling in Bannu District, Khyber Pakhtunkhwa Province, Pakistan from March 2019 to July 2019. A WHO validated questionaire was used. The outcome variable was parental refusal of routine immunization of their children. Logistic regression was performed for associations, and multi-regression was applied to identify any confounders. RESULTS Of 610 parents, 170 (27.9%) refused vaccination of their children. Of these, the majority of mothers had no education [n = 145 (85.3%); p = 0.03], and mothers were less likely to own a mobile phone than fathers [24 (14.1%) vs 152 (89.4%); p ≤ 0.001]. The vaccination refusal rate was higher in parents with food security [n = 88 (51.8%)] compared with parents with minimal food insecurity [n = 62 (36.5%)] and high food insecurity [20 (11.8%); p ≤ 0.05)]. On multi-variate logistic regression, fathers who were employed [adjusted odds ratio (OR) 0.59, 95% confidence interval (CI) 0.37-0.94; p = 0.02] and had a high level of education (adjusted OR 0.21, 95% CI 0.08-0.50; p ≤ 0.001) were less likely to refuse vaccination of their children. Parents with high food insecurity were more likely to refuse vaccination of their children (adjusted OR 2.2, 95% CI 1.0-0.50; p = 0.04) compared with parents with minimal food insecurity (adjusted OR 1.6, 95% CI 1.0-2.5; p = 0.02). CONCLUSION The vaccination refusal rate was very high among parents, and this was associated with inability to read or write, no education, owning a mobile phone, unemployment and food security.

Abstract
On 21 January 2019, public health authorities of two neighboring Austrian provinces reported an increase in measles cases. We investigated this occurrence to identify clusters of epidemiologically linked cases and the associated vaccination status in order to generate hypotheses on those factors explaining the size of the measles clusters. Probable cases were residents of the provinces of Styria or Salzburg with clinical presentation of measles after 1 January 2019 who were linked to a confirmed case using RNA virus detection. We collected data on age, rash onset, certificate-based vaccination status and reasons for being unvaccinated. Contact history was used to identify chains of transmission. By 11 March, we identified 47 cases, with 40 (85.1%) in unvaccinated patients. A cluster of 35 cases with a median age of seven years (IQR: 1–11) occurred between 9 January and 20 February in the province of Styria due to one transmission chain with four case generations. Of 31 vaccine-eligible cases, 25 (80.6%) were unvaccinated, of which 13 refused vaccination. Between 10 January and 1 March, we identified 12 cases as part of five unlinked clusters in the province of Salzburg. Each of these five clusters consisted of two generations: the primary case and the successive cases (median age: 22 years, IQR: 11–35). Eleven of 12 cases occurred in unvaccinated patients, with none of the 11 having a vaccination-refusing attitude. An extended measles cluster in a vaccination-refusing community, compared to five short-lived clusters concurrently occurring in the neighboring province, illustrates how vaccine refusal may hamper control of transmission.

Parental Hesitancy About Routine Childhood and Influenza Vaccinations: A National Survey. Pediatrics 2020; 146:e20193852.

Abstract
BACKGROUND AND OBJECTIVES The World Health Organization has designated vaccine hesitancy as 1 of the 10 leading threats to global health, yet there is limited current national data on prevalence of hesitancy among US parents. Among a nationally representative sample of US parents, we aimed to (1) assess and compare prevalence of hesitancy and factors driving hesitancy for routine childhood and influenza vaccination and (2) examine associations between sociodemographic characteristics and hesitancy for routine childhood or influenza vaccination. METHODS In February 2019, we surveyed families with children using the largest online panel generating representative US samples. After weighting, we assessed hesitancy using a modified 5-point Vaccine Hesitancy Scale and labeled parents as hesitant if they scored >3. RESULTS A total of 2176 of 4445 parents sampled completed the survey (response rate 49%). Hesitancy prevalence was 6.1% for routine childhood and 25.8% for influenza vaccines; 12% strongly and 27% somewhat agreed they had concerns about serious side effects of both routine childhood and influenza vaccines. A total of 70% strongly agreed that routine childhood vaccines are effective versus 26% for influenza vaccine (P < .001). In multivariable models, an educational level lower than a bachelor's degree and household income <400% of the federal poverty level predicted hesitancy about both routine childhood and influenza vaccines. CONCLUSIONS Almost 1 in 15 US parents are hesitant about routine childhood vaccines, whereas >1 in 4 are hesitant about influenza vaccine. Furthermore, 1 in 8 parents are concerned about vaccine safety for both routine childhood and influenza vaccines, and only 1 in 4 believe influenza vaccine is effective. Vaccine hesitancy, particularly for influenza vaccine, is prevalent in the United States.

Abstract
This cross-sectional survey determined the vaccine hesitancy related to Human papillomavirus (HPV) and the determinants among parents of adolescents aged 12 and 13 years in Italy. Data was collected through a self-administered questionnaire. Two-thirds of the parents (66.7%) had heard of HPV infection and knew that the vaccination was a preventive measure. Parents who had vaccinated their child against the HPV were more likely to have this knowledge. The vast majority (88%) considered the immunization useful for the prevention of HPV-related cancers with an average value of 8.4. This positive attitude was higher among parents who had heard of HPV infection and knew that vaccination was a preventive measure, who had received information from physicians, who had vaccinated their child against the HPV, who were concerned that their child could contract the HPV infection, and who needed information on HPV vaccination. More than half (57.9%) self-reported that they had vaccinated their child against HPV and only 6.2% had delayed the administration of a dose. One-third (33.3%) were hesitant toward anti-HPV vaccination with a total Parent Attitudes about Childhood Vaccines Survey (PACV) score ≥50. Unmarried respondents, those who had not heard of HPV infection and did not know that the vaccination was a preventive measure, who did not believe that the vaccination was useful for the prevention of HPV-related cancers, and who needed information on HPV vaccination were more likely to be hesitant. Communication and education strategies must be undertaken to ensure that parents are fully informed and health-care professionals should provide materials with details regarding the risk of acquiring a HPV infection and vaccine usefulness.
