Abstract
Background:
Vaccination is one of the most effective public health interventions, preventing millions of deaths globally. However, vaccine hesitancy persists, not only among the public, but also among healthcare professionals (HCPs), who serve as key sources of vaccine information. This study assesses HCPs’ vaccination attitudes and estimates the prevalence and determinants of vaccine hesitancy in the UAE.
Design and methods:
This cross-sectional, descriptive study surveyed HCPs across the UAE from March to October 2024 using a 57-item questionnaire adapted from previous literature. Univariate, bivariate (chi-squared test), and multivariate (logistic regression) analyses were conducted.
Results:
HCPs demonstrated generally positive attitudes towards paediatric vaccinations, with 84.29% expressing confidence in vaccine safety and efficacy. However, significant knowledge gaps were identified, particularly regarding vaccine adjuvants and long-term safety. Hesitancy was highest among mid-level professionals, including nurses, dentists, and pharmacists, with concerns about vaccine safety (47.87%) and adverse effects (57.67%) being major drivers. Additionally, 85.77% exhibited caution towards newly introduced vaccines, preferring to wait for broader community uptake. Time constraints limited vaccine discussions, and 71.9% of HCPs had never received formal training on addressing hesitancy.
Conclusion:
While HCPs generally support paediatric vaccinations, knowledge gaps and hesitancy towards new vaccines persist. Targeted professional education, particularly in vaccine safety and communication strategies, is crucial to strengthening vaccine advocacy. Addressing these gaps through tailored training programmes may enhance HCPs’ ability to effectively counter vaccine hesitancy and sustain high immunization coverage.
Introduction
Vaccination is one of the most consequential public health interventions; global immunization efforts have saved an estimated 154 million lives over the past 50 years. 1 Despite its success, global immunization coverage has declined over the past decade, more so after the COVID-19 pandemic.2,3
The 2022 WHO-UNICEF Estimates of Immunization Coverage (WUENIC) indicated that 25 million children missed out on one or more doses of DTP (Diphtheria, Tetanus, Pertussis) Vaccine through routine immunization services in 2021 alone—2 million more than in 2020 and 6 million more than in 2019. 4 The consequences of insufficient vaccine coverage are well-documented.5–8 A US modelling study estimated that for even a 5% reduction in MMR (Measles, Mumps, Rubella) coverage, a threefold increase in measles would be expected, costing the public sector an additional $2.1 million. 9 This issue is only expected to grow with the 2023 UNICEF State of the World’s Children report finding that perception of the importance childhood vaccination has declined more than 10 percentage points across Europe and Central Asia, with some countries seeing drops as high as 44%. 10
Vaccine hesitancy is a major driver of backslides in immunization rates globally, recently classified by the World Health Organization (WHO) as one of the 10 threats to Global Health. 11 WHO first defined vaccine hesitancy as the delay in acceptance or the refusal of vaccination despite availability of vaccination services. 12 In 2022, the concept has been refined as a motivational state of being conflicted about, or opposed to, getting vaccinated; this includes intentions and willingness. 13
Understanding the underlying factors driving hesitancy is essential for addressing this public health challenge. Evidence suggests that concerns about vaccine safety, efficacy, and novelty play a central role in shaping reluctance. 12 In the United Arab Emirates (UAE), an observational cross-sectional study revealed that 14% exhibited vaccine hesitancy, despite a high degree of trust in the national healthcare system. 14
Vaccine hesitancy is not confined to the general population but has also been observed among healthcare professionals (HCPs), who are conventionally regarded as the most authoritative sources of vaccine-related information. In a study conducted in the UAE, among the 45.8% healthcare workers who did not take the influenza vaccine, nearly half reported that “doubts about efficacy” was their main barrier against vaccination. 15 While this is distinct from paediatric immunization, such reluctance may reflect broader vaccine scepticism, potentially influencing public perception. Despite having vaccine coverage estimates above 95% for most childhood vaccines, vaccine preventable diseases continue to persist in the UAE. 16
Vaccine hesitancy among HCPs has been documented in various international contexts, further underscoring the urgency of this issue. A qualitative investigation conducted by the European Centre for Disease Prevention and Control (ECDC) in Croatia, France, Greece, and Romania identified pervasive scepticism regarding vaccine efficacy, concerns over adverse effects, and underlying distrust in pharmaceutical entities and regulatory institutions. 17 A recent study also reported that 32.1% of paediatric nurses expressed some degree of vaccine hesitancy, with hesitancy rates reaching 21.9% for the HPV vaccine and 17.5% for varicella. 18
Healthcare professionals serve as the primary intermediaries in vaccine advocacy, yet their own reservations regarding immunization may inadvertently contribute to public hesitancy. Previous studies in the UAE have highlighted a widespread deficiency in knowledge among physicians concerning adult vaccines, a lack of confidence in addressing patient concerns, and the influence of misinformation propagated through social media.19,20 Although a significant proportion of physicians acknowledge vaccine hesitancy as a public health concern, some express reluctance in engaging with hesitant parents due to fears of jeopardizing the physician-patient relationship. 16 The implications of this hesitancy extend beyond individual clinical encounters, as unaddressed scepticism may propagate vaccine reluctance within broader communities.
This study aims to comprehensively assess hesitancy towards paediatric vaccines among healthcare professionals in the UAE by exploring key factors influencing their attitudes in current times. Specifically, the research seeks to examine levels of confidence and knowledge regarding paediatric vaccines, quantify the extent of agreement with current vaccination practices, and identify prevailing concerns related to paediatric immunization. Furthermore, the study endeavours to determine predictors of vaccine hesitancy within this population, analysing how demographic, professional, and experiential factors contribute to reluctance or uncertainty. By expounding on these determinants, the study intends to provide evidence-based insights that may contribute to the development of targeted interventions to enhance vaccine confidence among healthcare professionals and, consequently, bolster vaccine uptake within the broader population.
Methodology
Questionnaire development
There is no standardized tool to measure vaccine hesitancy in healthcare professionals that has been widely used. We reviewed the Parental Attitudes towards Childhood Vaccines scale (PACV), 21 the WHO’s Vaccine Hesitancy Scale (VHS), 22 in addition to reviewing previous questionnaires from similar studies14,23 with some adjustments to better fit our objectives. The 57-item questionnaire was split into four main sections: demographics, knowledge of vaccines, recognizing importance of vaccines, and general vaccine hesitancy. Each section utilized a mixture of yes/no questions, single and multi-select questions as well as Likert scales. The questionnaire was developed in English. Pilot testing was conducted, and all feedback was reviewed and incorporated if appropriate. The developed questionnaire was uploaded to Google Forms to facilitate distribution. The tool and research plan were reviewed and approved by the University of Sharjah Research Ethics Committee (Reference Number: REC-24-02-26-02-F) and were conducted in accordance with all relevant guidelines and regulations. The questionnaire can be found in the Supplementary Material section.
Study population and data collection
This UAE cross-sectional study gathered data from healthcare professionals from 19th March 2024 to 12th October 2024, using convenience sampling. To be included, participants had to be healthcare professionals currently working in the UAE. Recruitment occurred though various channels including WhatsApp, emails, and Instagram, as well as in person by approaching professionals at their workplaces with QR codes. Using Cochran’s sample size formula and assuming a confidence level of 95%, sampling error of 5%, and a standard error of 1.96, the minimum required sample size was found to be 385. A total of 541 responses were included after removing those not meeting inclusion criteria. Before answering the questionnaire, participants were shown a Participant Information Sheet detailing the purpose and procedures of the study; only after providing written consent can a participant begin the study. Confidentiality was maintained by not collecting any identifying information and by ensuring the data was securely stored and only accessible to the investigators.
Statistical analysis
Only the researchers had access to the raw data. Data was exported from Google Forms to CSV format and processed in python-3 using the Matplotlib-v3.3.4, pandas-v1.2.4, and statsmodels-v0.12.2 packages for analysis and interpretation. Missing values were dealt with through pairwise deletion.
All baseline and demographic characteristics were used to identify determinants of vaccine hesitancy. Chi-squared tests were used for bivariate analyses and logistic regression was used for multivariate modelling. p-Values less than 0.05 were taken to be significant.
Results
Demographic data
A total of 541 HCPs participated in the study. Most of the participants identified as Arab (63.96%, n = 346), with 88 being Emirati (16.27%). A significant proportion were physicians (69.87%, n = 378), while other HCPs included pharmacists (10.72%, n = 58), dentists (9.98%, n = 54), and nurses (6.65%, n = 36).
Affiliations varied depending on their registration with the three health regulatory authorities in the UAE - Ministry of Health and Prevention (44.36%, n = 240), Dubai Health Authority (31.98%, n = 173) and Department of Health/Health Authority - Abu Dhabi (23.66%, n = 128). The majority of participants worked in government hospitals (61.74%, n = 334). Further demographics can be seen in Table 1.

Confidence and knowledge about paediatric vaccines
A large proportion of participants, 84.29% (n = 456) were confident in their knowledge of vaccine usage and efficacy, with very similar confidence in their knowledge of vaccine safety. However, confidence waned when it came to understanding the role of adjuvants, with 33.27% (n = 180) feeling unconfident.
It is important to highlight that a good proportion of healthcare professionals (HCPs) reported “I don’t know” when asked about the likelihood of vaccine-associated complications, particularly in context of long-term complications of vaccines with adjuvants (31.05%, n = 168). On a positive note, 73.01% (n = 395) consider it unlikely that there is a link between the measles vaccine and autism (Table 2).

Attitudes towards current vaccination practices
The results indicate that the participants exhibit good confidence in paediatric vaccinations. Most HCPs recognize the importance of vaccines in preventive care, with 88.36% (n = 478) either agreeing or strongly agreeing with this statement. There is a high level of confidence (94.82%, n = 513) in vaccines recommended by health authorities. Yet, a substantial proportion (85.77%, n = 464) of HCPs prefer to wait for broad community experience before recommending new vaccines, demonstrating a cautious approach.
Despite this, 86.51% (n = 469) of HCPs acknowledge their responsibility in educating parents about vaccines and recognize that acceptance is significantly impacted by their recommendations (90.94%, n = 492). Unfortunately, a significant proportion of HCPs (68.77%, n = 372) reported a lack of time for advising about vaccines, highlighting a systemic challenge in providing comprehensive vaccine education.
HCPs were asked to what extent they agree that it is very useful to vaccinate children against various illnesses and results are displayed in Figure 1.

Concerns surrounding paediatric vaccinations
Despite good confidence, participants expressed some concerns about vaccines. 37.71% (n = 204) were hesitant and 35.3% (n = 191) were unsure if new vaccines carry more risks than older vaccines. 57.67% (n = 312) expressed concerns about serious adverse effects of vaccines. When recommending vaccines, HCPs prioritized vaccine safety (47.87%, n = 259), vaccine effectiveness (45.84%, n = 248), and disease eradication potential (45.47%, n = 246). The least important factors were personal experience with the disease (13.12%, n = 71) and vaccine cost (11.46%, n = 62; Table 3).
Factors influencing recommendation of paediatric vaccinations.
Participants perceive that their patients’ perception of vaccination has shifted to more negative (30.5%, n = 165) to neutral (46.58%, n = 252) during the COVID-19 pandemic. When asked, how their own perceptions have changed during the pandemic, 37.52% (n = 203) concur that it has become more positive while 51.39% (n = 278) remained neutral.
Predictors of hesitancy towards paediatric vaccines
Bivariate analysis was done using Chi-Square for the demographic variables. Hesitancy towards paediatric vaccines was notably significant with certain professional roles and mid-level experience. Dentists (OR = 5.714, 95% CI = 1.846–17.690, p = 0.003), nurses (OR = 4.571, 95% CI = 1.076–19.434, p = 0.040) and pharmacists (OR = 4.229, 95% CI = 1.315–13.599, p = 0.016) demonstrated higher odds of hesitancy (Table 4).

Training needs to address vaccination concerns
Most of the HCPs (71.9%, n = 389) had not received any training to address vaccine hesitancy among parents. However, most of the HCPs were interested in receiving such training. 35.86% (n = 194) were interested, 20.33% (n = 110) were very interested, and 26.8% (n = 145) were neutral. Only 7.02% (n = 38) were not interested at all. A large majority of the HCPs (73.01%, n = 395) believed that such training should be part of university education (Table 5).

Discussion
This study explored the attitudes of healthcare professionals (HCPs) in the UAE towards paediatric vaccines, confidence in their safety and efficacy, and the factors influencing their recommendations.
Summary of results
This study provides insights into vaccine confidence and hesitancy among HCPs in the UAE. The key findings of this study highlight a generally positive attitude among HCPs towards paediatric vaccinations, coupled with high self-reported confidence in their knowledge of vaccine usage, safety, and efficacy. While confidence in paediatric vaccines was generally high (84.29%), significant knowledge gaps remained, particularly concerning vaccine adjuvants and long-term safety. A notable proportion (85.77%) exhibited caution towards newly introduced vaccines, preferring to wait for broader community uptake before recommending them.
Hesitancy was more pronounced among dentists, nurses, and pharmacists compared to physicians, with mid-level professionals displaying the highest levels of doubt. Concerns about vaccine safety (47.87%) and adverse effects (57.67%) were key drivers of hesitancy, compounded by time constraints limiting vaccine discussions. Despite their pivotal role in vaccine advocacy, 71.9% of professionals have never received formal training in addressing hesitancy, underscoring an urgent need for targeted professional education.
Vaccine hesitancy: Applying the 3C model
Vaccination, widely regarded as one of the most significant public health achievements, has paradoxically become a victim of its own success. As disease transmission declines, public awareness of the severity of these illnesses diminishes, leading some to underestimate the dangers of the disease while overestimating the risks associated with vaccination. 24 Strategic Advisory Group of Experts (SAGE) on Immunization, established by the World Health Organization (WHO), identifies the 3C model as factors associated with vaccine hesitancy—Confidence, Complacency, Convenience. 12
In context of our results, there was broad agreement on the importance of vaccination, with most participants expressing confidence in vaccines recommended by health authorities. However, there was also a noticeable level of complacency, as many preferred to wait for wider community uptake before endorsing newly introduced vaccines. While a cautious approach is understandable, delays in professional endorsement can undermine confidence in immunization programmes, especially for new or rapidly developed vaccines, as the public may perceive the delay as a lack of assurance. When comparing patients’ perceptions of vaccination before and during the pandemic, a third of healthcare professionals in this study observed that their patients’ views had shifted negatively. This is most likely fuelled by the spread of misinformation, contributing to greater complacency and hesitancy among some segments of the population.
In 2018, the model was revised to become the 5C model which encompassed confidence, complacency, constraints, calculation of risk and collective responsibility. 25 Undertaking this research is an attempt to understand the current risk of vaccine hesitancy in our community so we can take actions to mitigate it, as a community.
Is there a need for an urgent call to action?
Vaccines are recognized as having a critical role in preventing deaths and hospitalizations due to infectious diseases; estimates suggest that vaccines could have prevented nearly one-quarter (21.7%) of the 5.3 million deaths among children under the age of 5 years in 2019. 26
In 2023, the WHO reported that worldwide immunization rates for key vaccines, including the diphtheria-tetanus-pertussis (DTP3) series, had dropped to 84% from pre-pandemic rates of 86%. Similarly, the global vaccine coverage of children who received a first dose of measles vaccine was 83% in 2023, compared to pre-pandemic levels of 86% in 2019. 10 Measles is leading the resurgence of vaccine-preventable diseases. In 2024, the European Region saw 127,350 measles cases—double the 2023 count and the highest since 1997. Over 40% of cases were in children under 5, with more than half requiring hospitalization and 38 reported deaths as of March 2025. This highlights the urgent need for improved attitudes to vaccine preventable diseases. 27
Fortunately, the UAE has strong vaccination coverage, with the following rates for key vaccines: BCG at 98%, DTP third dose at 96%, Hep B third dose at 96%, Measles-containing vaccine second dose at 94%, Polio third dose at 94%, Rubella-containing vaccine first dose at 98%, and Rotavirus last dose at 91%. 28 These figures are close to or above the WHO-recommended 95% target for controlling vaccine-preventable diseases, though there are minor gaps in measles, polio, and rotavirus coverage.
Despite meeting WHO vaccination targets, the UAE saw an uptick in vaccine-preventable diseases like measles, mumps, and pertussis in 2024. 28 With expatriates making up 88.5% of the population, 29 global vaccine hesitancy trends could affect vaccination uptake in the UAE. As the population grows, particularly in cities like Dubai, 29 it’s crucial to address potential gaps in vaccine hesitancy to ensure continued public health success.
The findings reveal a paradox in vaccine hesitancy, where parents express confidence in vaccines’ importance and effectiveness but also voice concerns about side effects and necessity. Despite these concerns, most continue to vaccinate their children, indicating a more nuanced form of hesitancy not fully captured by current surveys. For example, in a study conducted in Jordan by Barakat et al. 30 over 85% of participants hesitated about the MMR vaccine, but more than 90% had never refused or delayed vaccinations.30 This suggests a distinction between expressed hesitancy and behavioural hesitancy, highlighting the complexity of modelling vaccine hesitancy in public health research.
Sociodemographic predictors of hesitancy
A qualitative study in the UAE in 2020 identified several attitudes towards vaccinations, the negative ones included pressure from parents and grandparents who discourage immunization by citing their own experiences. Fear of side effects and health concerns were also prevalent. Additionally, the growing influence of social media and influencers negatively impacted vaccine perceptions, while healthcare professionals noted their own lack of engagement on social platforms due to time constraints, job restrictions, and low confidence in their communication skills. 16 This is corroborated by the quantitative data from this study. Despite strong overall support for vaccination, concerns about vaccine safety and adverse effects were noted.
Additionally, hesitancy was more pronounced among non-physician healthcare professionals, including dentists, pharmacists, and nurses. This is consistent with previous research suggesting that HCPs who are less directly involved in vaccine administration may feel less confident in their knowledge, potentially contributing to greater uncertainty. This study also found that mid-level professionals were more likely to express hesitancy compared with those at entry-level or senior positions, suggesting that experience and continuous professional development play a role in shaping vaccine confidence.
Several studies have shown a strong correlation between healthcare profession or education level and vaccine hesitancy. 31 In Finland and Croatia, nurses exhibited higher vaccine hesitancy than physicians,32,33 while in France, hospital nurses were more hesitant than community nurses. 34 A European study found that medical students’ trust in vaccines grew with the duration of their studies. 35 Karlsson et al. 32 in Finland found that doctors had the highest confidence in vaccine safety and efficacy, with nurses’ confidence increasing with their education level. 32 These variations in hesitancy among healthcare professionals can also be linked to their involvement in vaccination efforts.
Ensuring that all HCPs, regardless of their professional background, have access to up-to-date immunization education may help to reduce variability in vaccine-related attitudes.
Developing tools for healthcare professionals to address vaccine hesitancy
Our study found that many HCPs rely primarily on medical experience and international guidelines as their sources of information about vaccines. A systematic review identified that vaccination-related training across medical, nursing, and pharmacy programmes is inconsistent, with only 21% of participants feeling adequately educated on the topic. 36 While content generally focuses on vaccination principles, a consistent gap exists in teaching communication strategies and practical skills necessary for addressing vaccine hesitancy. Additionally, there is no clear guidance on how to select and implement the most appropriate interventions to address vaccine hesitancy in different clinical contexts, as comparative studies evaluating interventions are scarce. 36
Given the significant influence healthcare professionals have on vaccine attitudes, enhancing both knowledge and communication skills is essential. Many HCPs expressed interest in further education, yet formal training on addressing vaccine hesitancy remains limited. Internationally, structured training programmes have demonstrated effectiveness in improving healthcare professionals’ ability to address vaccine concerns. 37 Tailored interventions targeting both knowledge sharing and communication skills are necessary to improve vaccine confidence. However, it remains difficult to quantify the impact of these interventions in terms of actual behavioural change in parents. Strengthening local guidelines and fostering multidisciplinary collaboration could further support vaccine advocacy practices and reduce hesitancy.
Further recommendations
This study highlights the need for healthcare professionals in the UAE to remain vigilant and avoid complacency regarding the success of current vaccination programmes. Despite positive outcomes, global trends indicate rising vaccine hesitancy, necessitating continued efforts to maintain trust in the system. Future research should focus on developing a validated scale to quantify vaccine hesitancy among healthcare professionals. Additionally, stronger tracking systems for vaccine-preventable diseases are essential to detect outbreaks and disease resurgence early, especially considering potential declines in vaccination rates. Lastly, intervention studies could be used to assess training models and evaluate their impact on healthcare professionals’ and parents’ attitudes and confidence in vaccines. By addressing these areas, future research can contribute to sustaining vaccine success and public health in the UAE and around the world.
Limitations of the study
While this study provides valuable insights, it is not without limitations. Firstly, the cross-sectional design restricts causal inferences, providing only a snapshot of attitudes at a specific point in time. Secondly, the reliance on self-reported data introduces a risk of social desirability bias, where participants might underreport hesitancy due to perceived professional expectations. The sample’s demographic composition, with most participants being physicians and those working in government hospitals, may also limit the generalizability of findings to other HCPs or private sector practitioners.
Additionally, while the study identifies significant associations between certain professions and vaccine hesitancy, it does not explore the underlying factors driving these differences, such as variations in training or exposure to vaccine-related information.
Conclusion
In conclusion, this study reveals generally positive attitudes among healthcare professionals towards paediatric vaccinations, with high confidence in vaccine safety and efficacy. However, significant knowledge gaps remain, especially regarding vaccine adjuvants and long-term safety. Additionally, a large proportion of HCPs expressed caution towards newly introduced vaccines, preferring to wait for broader community uptake. These findings highlight the need for tailored training programmes addressing knowledge gaps and communication skills.
