Background: Vaccine hesitancy (VH) represents a growing concern among healthcare professionals and students, potentially undermining public health efforts. Nursing, pediatric nursing, and midwifery students are future vaccinators and educators, making it essential to understand their attitudes, knowledge, and confidence toward vaccination. This study aims to assess vaccine-related perceptions and behaviors among these student populations in an Italian university. Methods: A cross-sectional survey was conducted between November 2022 and February 2024 at the University of Rome “Tor Vergata”. A structured, anonymous questionnaire, including the Vaccination Attitudes Examination (VAX) scale, vaccine knowledge items, and sources of information, was administered to students in nursing (n = 205), pediatric nursing (n = 46), and midwifery (n = 21). Statistical analyses included descriptive statistics, ANOVA, post hoc tests, and Mann–Whitney U tests. Results: Among the 272 participants, 20.6% reported refusing at least one recommended vaccine, and 18.4% delayed vaccination for non-medical reasons. Vaccine knowledge and confidence increased significantly with academic progression (p < 0.001). Midwifery students showed both the highest concern for long-term vaccine effects and the greatest confidence in vaccine safety. Institutional and scientific sources were the most trusted, though traditional and non-institutional media also influenced perceptions, particularly among midwifery students. Conclusions: Despite high COVID-19 vaccine uptake, VH persists among health professional students. Discipline-specific patterns highlight the need for early, targeted educational strategies to enhance vaccine literacy and reduce hesitancy. Tailored training may empower future professionals to become informed and credible advocates for vaccination. Full article

Background/Objectives: Medical and nursing students, as future healthcare professionals, influence public trust and vaccine acceptance. Knowledge gaps or misconceptions regarding immunization may undermine their confidence and effectiveness in addressing vaccine hesitancy. This study explores perceptions and attitudes toward childhood vaccination among Bulgarian healthcare students and factors shaping these outcomes. Methods: A cross-sectional survey was conducted in 2024, using an online self-administered questionnaire completed by 374 medical and nursing students. Descriptive statistics were used to analyze vaccine-related responses, comparing attitudes between healthcare programs and education years. Binomial logistic regression was applied to identify predictors of support for mandatory vaccination, first considering demographic and academic variables, and then adding students’ beliefs and common misconceptions. Results: Medical students showed more positive attitudes toward vaccination than nursing students, with 96.8% of medical students versus 89.4% of nursing students believing vaccines are effective (p = 0.005). Students in advanced years demonstrated stronger belief in vaccine effectiveness (p = 0.038). Additionally, misbeliefs about the measles vaccine causing autism decreased significantly, with most students in higher years rejecting this misconception (p = 0.009). Logistic regression revealed that belief in following the vaccine schedule (OR = 22.71; p < 0.001) and confidence in vaccine effectiveness (OR = 10.20; p < 0.001) were the strongest predictors of support for mandatory vaccination, with attitudinal factors explaining over half of the variance. Conclusions: Healthcare students’ attitudes about vaccination influence public health outcomes, as their perspectives reflect experience and beliefs. Targeted vaccine education helps address misconceptions and improve vaccination rates. Full article

Background/Objectives: Vaccine hesitancy is becoming an increasing concern, leading to preventable outbreaks of infectious diseases. During the COVID-19 pandemic, the United States served as an intriguing case study for exploring how risk perception and trust in health authorities, including scientists, are influenced by government policies and how these factors affect vaccine hesitancy. Methods: We conducted a secondary analysis using the MIT COVID-19 Survey dataset to investigate whether risk perception and trust differ between states governed by Democratic or Republican governors. Results: Our analysis (n = 6119) found that participants did not vary significantly by state political affiliation in terms of their sociodemographic factors (such as age, gender, self-rated health, education, and whether they live in a city, town, or rural area), their perceived risk for the community, or their ability to control whether they become infected. However, there was a difference in the perceived risk of infection, which was higher in states governed by Republicans. Trust also varied by gubernatorial affiliation, with higher levels of trust reported among residents of Democratic-leaning states. We also found a strong mediation effect of trust on vaccine hesitancy, but this was not the case for risk perception. Conclusion: Therefore, it appears that vaccine acceptance relies on trust in health authorities, which is influenced by governmental policies. State officials should work with local health officials to build trust and increase timely responses to public health crises. Full article

Ensuring sustainable food systems is an urgent global priority as populations grow and environmental pressures mount. Technological innovations such as genetic engineering (GE) and nanotechnology (nano) have been promoted as promising pathways for achieving greater sustainability in agriculture and food production. Yet, the sustainability of these technologies is not defined by technical performance alone; it hinges on how they are perceived by key stakeholders and how well they align with broader societal values. This study addresses the critical question of how expert stakeholders evaluate the sustainability of GE and nano-based food and agriculture (agrifood) products. Using a multi-method online platform, we engaged 42 experts across academia, government, industry, and NGOs in the United States to assess six real-world case studies—three using GE and three using nano—across ten different dimensions of sustainability. We show that nano-based products were consistently rated more favorably than their GE counterparts in terms of environmental, economic, and social sustainability, as well as across ethical and societal dimensions. Like prior studies, our results reveal that stakeholders see meaningful distinctions between nanotechnology and biotechnology, likely due to underlying value-based concerns about animal welfare, perceived naturalness, or corporate control of agrifood systems. The fruit coating and flu vaccine—both nano-enabled—received the most positive ratings, while GE mustard greens and salmon were the most polarizing. These results underscore the importance of incorporating stakeholder perspectives in technology assessment and innovation governance. These results also suggest that responsible innovation efforts in agrifood systems should prioritize communication, addressing meaningful societal needs, and the contextual understanding of societal values to build trust and legitimacy.

COVID-19 vaccine hesitancy in Pakistan is a barrier to optimal vaccine uptake and has been situated within a context of hesitancy towards other vaccines. A mixed-methods study was conducted during the initial COVID-19 vaccine roll-out in 2021 in four union councils in Peshawar, consisting of a cross-sectional survey, eight focus group discussions (FGDs) with community members and eight in-depth interviews with healthcare workers (HCWs) to assess perceptions toward vaccines. Multivariable logistic regression was used to assess factors associated with COVID-19 vaccine hesitancy. Of 400 survey participants, 57.3% were vaccine acceptant and 42.8% vaccine hesitant. Just over half (56.8%) perceived COVID-19 vaccines to be safe. Most (88%) reported trust in HCWs to provide accurate vaccine information. FGDs revealed that women received less information about the vaccine compared to men and cultural restrictions were barriers even for those willing to be vaccinated. Correlates of vaccine acceptance included male sex (aOR 2.25; 95% CI 1.29–3.91), age 50 years or greater (aOR 1.74; 95% CI 1.19–6.31), social network support (e.g., vaccine acceptance among an individual’s social network) in receiving COVID-19 vaccines (aOR 2.38; 95% CI 1.45–3.89), community concern about COVID-19 spread (aOR 2.84; 95% CI 1.73–4.66), and trust in HCWs to provide vaccine information (aOR 3.47; 95% CI 1.62–7.42). Future vaccine promotion should prioritize engaging community leaders, sharing transparent information, combatting misinformation and rumors, and implementing household-based interventions especially targeting the importance of vaccination among women and young people to increase uptake.

Infectious disease outbreaks amplify the influence of stressors on psychological conditions. The purpose of this study was to analyze the disturbing influence of COVID-19 outbreak-related information and the influence of trust on the Serbian healthcare system and COVID-19 preventive measures on anxiety and depression. An anonymous online questionnaire assessing the demographic information, disturbance level and causes, and levels of anxiety and depression has been distributed to the participants, divided into student and non-student groups. The non-student group was further divided into healthcare, military, and education workers. Anxiety and depression levels, as well as the level of decreased trust in COVID-19-related preventive measures, were higher among students compared to non-students (p = 0.011). Higher anxiety and depression levels, and higher influence of the COVID-19 outbreak on those levels, were observed in education and healthcare workers, compared to military personnel. Medical doctors reported a higher level of trust in the healthcare system compared to nurses (p = 0.023). Trust in the healthcare system increased more frequently compared to the pre-vaccination period among medical doctors, compared to nurses (p = 0.040). Higher anxiety and depression and lower public trust levels in students and workers in education and the healthcare sector indicate a need to focus on these important society members during public health emergencies.

Background: The COVID-19 pandemic prompted extensive vaccination efforts globally, yet in the Philippines, many families remained unvaccinated. Caregivers are key decision-makers for family vaccination, but evidence on factors influencing their own vaccine uptake is limited. Methods: A cross-sectional survey of primary caregivers was conducted in low COVID-19 vaccine uptake regions in the Philippines from July to October 2023 using a validated questionnaire. Multivariable logistic regression identified enablers and barriers to vaccine uptake. Results: Among 775 respondents, 72.3% completed primary vaccination, 3.3% had incomplete vaccination, and 24.4% were unvaccinated. Key factors for vaccination included self, family, and community protection, and the influence of government regulations. Distrust in vaccine safety was the main barrier. Positive associations with vaccine uptake were found for age [30–45 years (aOR = 2.23) and 46–59 years (aOR = 2.84)], education [secondary (aOR = 2.25) and tertiary (aOR = 4.93)], and employment (aOR = 1.99). Confidence in vaccine safety (aOR = 1.92), vaccine effectiveness (aOR = 2.23), and satisfaction with vaccination efforts (aOR = 2.39) were additional enablers. Disagreement with restrictions on the unvaccinated was a barrier (aOR = 0.31). Conclusions: This study identified multiple factors influencing COVID-19 vaccination among primary caregivers in low uptake areas of the Philippines. Interventions addressing perceptions about vaccine safety and effectiveness, particularly among younger and less educated caregivers, may improve public trust and satisfaction with vaccination efforts.

Background/Objectives: Preventive health behaviors are key to disease prevention and health system sustainability; however, population-level factors remain understudied in multilingual regions. South Tyrol, an autonomous multilingual province in Northern Italy, provides a unique setting to examine how sociodemographic and linguistic factors shape preventive behaviors. Methods: A stratified, population-representative survey of 2090 adults (aged ≥18 years) was conducted in South Tyrol in 2024. Preventive behavior was assessed using the validated 16-item Good Health Practices Scale (GHP-16). Key predictors included age, sex, education, living situation, language group, employment in the health/social sector, health literacy (HLS-EU-Q16), patient activation (PAM-10), and the mistrust of professional health information. Weighted statistics and multivariable linear regression were used to identify associations. Results: The GHP-16 scores varied significantly across sociodemographic and psychosocial strata. Female sex, older age, higher education, higher patient activation, and sufficient health literacy were independently associated with greater engagement in preventive behaviors. Patient activation showed the strongest graded effect (β = 1.739). The mistrust of health professionals was inversely associated with behavior (β = –0.050, 95% CI: –0.090 to –0.009). Italian speakers reported higher GHP-16 scores than German speakers (β = 0.377), even after adjusting for covariates. Item-level analysis revealed small but consistent differences, particularly in information-seeking and vaccination behavior. Conclusions: Preventive behaviors in South Tyrol are shaped by demographic, psychosocial, and linguistic factors. Patient activation and health literacy are key modifiable predictors, whereas language group differences suggest structural and trust-related disparities that require tailored public health strategies in multilingual settings.

Background: Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States (U.S.) and a major contributor to several cancers, including cervical, anal, penile, and oropharyngeal cancers. Although a safe and effective vaccine is available, HPV vaccination rates remain suboptimal, particularly among racial, ethnic, and immigrant minority groups. This study explored multiple factors, such as cultural, social, and structural influences, influencing HPV vaccine decision-making among Cape Verdean immigrant parents in the U.S., a population currently underrepresented in HPV research. Methods: Qualitative study using individual, in-depth interviews with Cape Verdean immigrant parents of children aged 11 to 17 years living in the U.S. Interviews were transcribed verbatim and analyzed thematically using the social ecological model (SEM) to identify barriers and facilitators at the intrapersonal, interpersonal, organizational, community, and policy levels. Results: Forty-five Cape Verdean parents (27 mothers, 18 fathers) participated. Fathers were significantly older than mothers (50.0 vs. 41.1 years, p = 0.05). Most were married or partnered (60%), had at least a high school education (84.4%), and reported annual household incomes of US$50,000 or more (66.7%), with no significant gender differences. Nearly all spoke Creole at home (95.6%). Fathers had lower acculturation than mothers (p = 0.05), reflecting less adaptation to U.S. norms and language use. Most parents had limited knowledge of HPV and the vaccine, with gendered beliefs and misconceptions about risk. Only seven mothers (25.9%) reported receiving a provider recommendation; all indicated that their children had initiated vaccination (1 dose or more). Mothers were the primary decision-makers, though joint decision-making was common. Trust in providers was high, but poor communication and the lack of culturally and linguistically appropriate materials limited informed decision-making. Stigma, misinformation, and cultural taboos restricted open dialogue. Trusted sources of information included schools, churches, and Cape Verdean organizations. While parents valued the U.S. healthcare system, they noted gaps in public health messaging and provider engagement. Conclusions: Findings revealed that HPV vaccine uptake and hesitancy among Cape Verdean immigrant parents in the U.S. were influenced by individual beliefs, family dynamics, healthcare provider interactions, cultural norms, and structural barriers. These findings highlight the need for multilevel strategies such as culturally tailored education, community engagement, and improved provider communication to support informed vaccination decisions in this population.

The realities of the COVID-19 pandemic and the decision to control it through a worldwide vaccination programme brought to the forefront the debates about people’s attitudes towards vaccines and vaccination in general, and people’s attitude towards COVID-19 vaccines and vaccination, in particular. This study focuses on trust in hospitals, as a predictor of Romanians’ hesitancy towards vaccination. The study utilizes a longitudinal approach, examining data from two distinct periods: 2019, before the COVID-19 pandemic; and 2021, during the COVID-19 pandemic. Our findings show that the COVID-19 pandemic has altered public attitudes towards vaccination and may also have compromised the link, considered implicit before the pandemic, between the level of trust in the medical system and favorable attitudes towards vaccination.

Introduction: In the United States, vaccine hesitancy is higher among rural and racially and ethnically diverse communities, and messaging from trusted individuals may increase vaccine acceptance. The purpose of this study is to understand vaccine hesitancy, messaging from trusted individuals, and vaccine acceptance strategies among racially and ethnically diverse, medically underserved rural populations. Methods: The researchers conducted 12 in-person focus groups, each consisting of 5 to 12 participants, with community members and trusted leaders from three rural counties in Eastern North Carolina (n = 119). Thematic analysis was used to synthesize insights from the discussions, allowing for the identification of recurring patterns and community-specific considerations regarding vaccine perceptions and messaging. Results: The researchers identified seven key themes within the primary focus areas of the study: factors influencing vaccine hesitancy, messaging from trusted individuals, and strategies to improve vaccine acceptance. Participants reported differences in trust based on how long a vaccine has been available, concerns about becoming sick after a vaccine, seeing the symptoms of vaccine-preventable diseases, and misinformation on social media. Overall, participants reported trust in messages from medical providers. Trusted leaders advised people to conduct their own research on vaccines when determining whether to receive vaccinations. Lastly, social determinants such as cost, education, and transportation were identified as key barriers to vaccination. Conclusions: Our findings indicate that medical providers are trusted messengers for vaccine information and the promotion of vaccine uptake. However, distrust linked to fear, misinformation, and structural barriers persist. Public health efforts to increase vaccination confidence among rural, racially and ethnically diverse populations in the United States Southeast should address these factors in future vaccine interventions and educational efforts.

The coronavirus pandemic has spread globally, affecting over 700 million people and resulting in over 7 million deaths. In response, global pharmaceutical companies and disease control centers have urgently sought effective treatments and vaccines. However, the rise of counterfeit drugs has become a significant concern amid this urgency. To standardize the legal provision and usage of genetic resources, the United Nations Development Program (UNDP) introduced the Nagoya Protocol. Despite advancements in drug research, the production process remains tedious, complex and vulnerable to fraud. FairChain addresses this pressing challenge by creating a transparent ecosystem that builds trust among all stakeholders throughout the Drug Development Life Cycle (DDLC) by using decentralized, immutable, and transparent blockchain technology. This makes FairChain the first digital health tool to implement the principles of the UNDP’s Nagoya Protocol among all stakeholders throughout all DDLC stages, starting with sample collection, to discovery and development, to preclinical research, to clinical development, to regulator review, and ending with post-market monitoring. Therefore, FairChain allows pharmaceutical companies to document the entire drug production process, landowners to monitor bio-samples from their land, doctors to share clinical research, and regulatory agencies such as the Food and Drug Authority to oversee samples and authorize production. FairChain should enhance transparency, foster trust and efficiency, and ensure a fair and traceable DDLC. To date, no blockchain-based framework has addressed the integration of traceability, auditability, and Nagoya Protocol compliance within a unified system architecture. This paper introduces FairChain, a system that formalizes these requirements in a modular, policy-aligned, and verifiable digital trust infrastructure. Full article

Background: Immunization coverage in Nigeria is low, with many children missing out on important lifesaving vaccines. To enable a better understanding of contextual factors towards increasing uptake, we piloted a Decentralized Immunization Monitoring (DIM) approach in the Kumbotso local government area (LGA) of Kano state, Nigeria, to identify wards with low vaccination rates and understand why this is happening. The findings were used to improve routine immunization (RI) programs and reduce the number of unvaccinated children and children yet to receive their first dose of diphtheria–pertussis–tetanus (DPT) vaccine, referred to as Zero-Dose children (ZD). Methods: This study adopted a cross-sectional design approach using the Behavioural and Social Drivers of Vaccination (BeSD) framework and the Lot Quality Assurance Sampling (LQAS). The study population comprised caregivers of children aged 0–11 months and 12–23 months across the 11 wards in Kumbotso District, Kano State, Nigeria, using a segmentation sampling approach. The study covered 209 settlements selected using probability proportionate to size (PPS) sampling from the wards. Univariate and bivariate analyses were performed to show patterns and relations across variables. Results: Out of 418 caregivers surveyed, 98.1% were female. Delayed vaccination was experienced by 21.9% of children aged 4.5–11 months, while the prevalence of ZD was estimated at 26.8% amongst the older cohort (12–23 months). A total of 71.4% of the delayed group and 89.1% of the ZD group remained unvaccinated. Caregiver education, rural residence, and home births correlated with delayed/ZD status (p < 0.05). Logistic regression associated higher caregiver education with reduced delayed vaccination odds (OR:0.34, p < 0.001) and urban residence with lower ZD odds (OR:1.89, p = 0.036). The antigen coverages of BCG (81.5%), DPT3 (63.6%), and measles 1 (59.7%) all surpassed the national dropout thresholds. Kumbotso, Unguwar Rimi, and Kureken Sani wards were all identified as underperforming and therefore targeted for intervention. Negative vaccine perceptions (50% delayed, 53.6% ZD) and distrust in health workers (46.4% delayed, 48.2% ZD) were significant barriers, though the caregiver intent to vaccinate was protective (OR: 0.27, p < 0.001). The cost of accessing immunization services appeared to have a minor effect on coverage, as the majority of caregivers of delayed and ZD children reported spending less than 200 Naira (equivalent to USD 0.15) on transport. Conclusions: This pilot study highlighted the utility of LQAS and BeSD in identifying low-performing wards, barriers, and routine immunization gaps. Barriers included low caregiver education, rural residence, and negative vaccine perceptions/safety. Caregiver education and urban residence were protective factors against delayed and ZD vaccination, suggesting social and systemic barriers, particularly in rural and less educated populations. Antigen-specific coverage showed disparities, with dropouts for multi-dose vaccines exceeding the national thresholds of 10%. Targeted measures addressing education, trust, and systemic issues are needed. Findings emphasize decentralized monitoring, community engagement, and context-specific strategies to reduce ZD children and ensure equitable vaccination in Nigeria. Full article

The 8th meeting of the African Advisory Committee on Vaccine Safety (AACVS), constituted in 2021, convened by the Vaccine Research and Innovation Unit within the Vaccine Preventable Diseases Program, WHO Regional Office for Africa, was held virtually from 14 to 16 April 2025. The meeting brought together independent vaccine experts to provide advice to the Regional Director, WHO, on vaccine safety issues critical to the African region. Discussions focused on critical updates regarding ongoing regional outbreaks, safety data, and associated safety concerns, with emphasis on newly introduced vaccines, including the malaria vaccines (RTS, S and R21), the MenFive pentavalent meningitis vaccine, and the Mpox vaccines—MVA-BN and LC16—alongside the ongoing Mpox response. The Committee conducted a deep dive into comprehensive safety considerations for new vaccine introduction, active surveillance strategies, strengthening the responsiveness of pharmacovigilance systems, and advancing vaccine research and development in Africa. Key observations highlighted significant gaps in safety surveillance systems. These included delays in data collection, access, and signal detection; a lack of harmonized real-time monitoring frameworks; the underutilization of digital technologies; and inadequate manufacturer responsibilities and accountability in post-market safety monitoring. The meeting concluded with a call to action emphasizing the need for sustainable pharmacovigilance funding mechanisms, improved regional coordination, real-time data sharing, standardized early safety study protocols, strengthened manufacturer accountability, and investments in risk communication and community engagement to bolster public trust. Strengthening vaccine safety systems and enhancing regional collaboration were recognized as urgent priorities to support the safe and effective deployment of vaccines and protect public health across Africa.

The World Health Organization (WHO) Global Benchmarking Tool (GBT) classifies regulatory systems into four maturity levels, with Maturity Level 3 (ML3) signifying a stable and effective regulatory environment. As of January 2025, eight African nations—Egypt, Ghana, Nigeria, Rwanda, Senegal, South Africa, Tanzania, and Zimbabwe—have attained ML3 status, marking a significant milestone in the continent’s regulatory landscape. Achieving ML3 confers critical benefits, including reducing substandard and falsified medicines, which enhances public health safety and fosters trust in healthcare systems. This progress encourages local manufacturing, diminishing reliance on imported medicines and promoting economic development. Furthermore, ML3 NRAs are better equipped to address public health emergencies, enabling swift approvals for vaccines and therapeutics while upholding safety standards. Nonetheless, challenges persist, including fragmented regulatory systems, the prevalence of counterfeit medicines, and limited resources. Overcoming these hurdles necessitates enhanced organizational capacity, investments in training, and the promotion of collaboration among NRAs. There is an urgent call for greater political commitment and resource allocation to strengthen regulatory systems across Africa. Achieving and maintaining ML3 status is essential for enhancing medicine regulation, supporting local manufacturing, and improving public health outcomes across the continent. While progress has been made, sustained efforts are crucial to tackling existing challenges and harnessing the full potential of advanced regulatory frameworks. Full article
