Willingness to accept the HBV vaccine and related factors: Administering the vaccination attitudes examination scale to Urban Vietnamese adults

Self-reported hepatitis B vaccination uptake and associated factors among adults in a tertiary hospital, Nasarawa State, Nigeria

Hepatitis B virus (HBV) infection remains a major public health challenge in sub-Saharan Africa despite the availability of a safe and effective vaccine. In Nigeria, adult vaccination coverage and completion rates are not well characterized within hospital-based populations. A hospital-based cross-sectional study was conducted among 1,200 adults attending Federal Medical Centre (FMC) Keffi, Nasarawa State, Nigeria. Data on socio-demographics, HBV-related knowledge, attitudes, perceived barriers, vaccination uptake, and completion were collected using a structured questionnaire. Knowledge and attitude scores were categorized into poor, fair, and good levels. Associations between socio-demographic characteristics and vaccination uptake were examined using chi-square and Fisher’s exact tests, with statistical significance set at p < 0.05. The mean age of respondents was predominantly 36–40 years (32.5%), with males constituting 72.3%. Most respondents had tertiary education (91.8%) and were civil servants (83.4%). Overall awareness of HBV was high (95.5%), with a mean knowledge score of 12.37 ± 1.42. Good knowledge was observed in 74.2% of respondents, while 57.2% demonstrated good attitudes toward HBV prevention. Vaccination uptake was high, with 93.5% reporting receipt of at least one vaccine dose. However, only 22.3% had completed the recommended three-dose schedule, while 48.2% and 23.1% had received one and two doses, respectively. Willingness to complete vaccination was reported by 81.6% of respondents. Perceived barriers included high vaccine cost (72.4%), inadequate access to health facilities (96.9%), fear of side effects (71.9%), and insufficient information (73.5%). No significant associations were found between socio-demographic variables and vaccination uptake (p > 0.05 for all). Despite high HBV vaccination initiation and knowledge levels, substantial gaps in vaccine completion persist. Addressing financial, informational, and access-related barriers is essential to improve full vaccination coverage among Nigerian adults.

HPV vaccination intention and its association with vaccine hesitancy and health beliefs among unvaccinated Chinese medical college students: A cross-sectional study

Background Human papillomavirus (HPV) infection poses a significant public health challenge, and HPV vaccination uptake among Chinese college students remains suboptimal. Therefore, it is essential to conduct ongoing, in-depth investigations into the psychological and cognitive mechanisms of HPV vaccination intention. This study aims to explore the associations among HPV vaccination intention, vaccine hesitancy, and health beliefs among Chinese medical college students. Methods A cross-sectional survey was conducted from June 16 to July 16, 2024, to assess sociodemographic characteristics, vaccine hesitancy, and health belief model (HBM) among college students at Guangdong Medical University. Descriptive statistics, univariate analysis, and binary logistic regression were performed to identify factors associated with HPV vaccination intentions among unvaccinated students. Results Among 3,584 unvaccinated participants, 73.16% expressed willingness to receive the HPV vaccine. The key significant associations identified included gender (male) (OR: 0.26; 95% CI: 0.22 ~ 0.31; p  <  0.001), parental occupation (employees in enterprises, commercial, and service industries (including self-employed)) (OR: 1.43; 95% CI: 1.18 ~ 1.75; p  <  0.001), and information sources (hospitals or doctors) (OR: 1.37; 95% CI: 1.15 ~ 1.64; p  =  0.001). Vaccination intention was also directly associated with the perceived necessity (OR: 0.91; 95% CI: 0.88 ~ 0.94; p  <  0.001) and importance (OR: 1.07; 95% CI: 1.03 ~ 1.10; p  <  0.001) of vaccine hesitancy, as well as the perceived benefits of behavior for the HBM (OR: 1.21; 95% CI: 1.12 ~ 1.32; p <  0.001). Conclusions In this sample, Chinese medical college students demonstrated a relatively high willingness to receive HPV vaccination. Willingness was positively associated with perceived necessity, importance, and benefits of vaccination. Integrating structured clinician-delivered counseling into curricula, using parental occupation data for targeted subsidies, and embedding classroom sessions comparing personal HPV risk with vaccine safety data may improve uptake. Government evaluation of gender-neutral vaccination policies and provision of male-inclusive campus services are also recommended.

Factors influencing HPV vaccination intention and uptake behaviors among medical students based on the health belief model and vaccine hesitancy theory: a cross-sectional study

Background HPV infection is the leading cause of cervical cancer. HPV vaccination coverage among young people in China remains low. Medical students, as a high-risk group and future health educators, are critical for cervical cancer control. Methods A questionnaire survey was conducted among 1,244 medical students from April to May 2026. Data were analyzed using SPSS 26.0, including t-test, correlation, regression, and serial mediation analysis (PROCESS Model 6). Results Among 1,203 valid participants (51.0% male, 49.0% female, 71.8% having received HPV vaccines), HPV knowledge was positively correlated with both vaccination intention and actual vaccination behavior. The serial chain mediation analysis specifically focused on vaccination intention: HPV knowledge showed a significant direct associational link with vaccination intention (β = 0.1238, p < 0.001). Perceived susceptibility and perceived severity served as significant serial mediators for intention. Conclusion HPV knowledge is correlated with vaccination intention via direct associations and serial mediating associations of perceived susceptibility and perceived severity. Based on these cross-sectional correlational findings, interventions targeting HPV knowledge improvement may correlate with elevated risk perception and stronger vaccination intention.

Changes in HPV vaccine hesitancy and influencing factors among female university students in China: A national repeated study

ABSTRACT HPV vaccine hesitancy remains a critical barrier to cervical cancer prevention in China despite a series of strategic policy initiatives. Our study conducted two large-scale online cross-sectional surveys in 2022 and 2025 among nationally representative samples of female university students, applying propensity score matching to enhance comparability. HPV vaccine hesitancy, assessed on a 0–10 scale (including graded hesitancy and refusal), increased significantly over time, with prevalence rising from 8.8% to 21.6%, and mean hesitancy scores also increasing. Although HPV knowledge improved and exposure to negative information declined, the perceived necessity of vaccination fell markedly, and trust eroded across several domains, including trust in health professionals’ advice and in both domestic and imported vaccines. Multivariable analyses identified perceived necessity, healthcare professional recommendation, and trust in professionals and domestic vaccines as protective factors, while prior self-payment for other vaccines was also associated with lower hesitancy. These determinants remained stable over time, underscoring the need for targeted strategies to counter rising hesitancy.

Factors affecting parental practices and attitudes toward influenza vaccination for children in China.

Investigation of parents' knowledge, attitudes, and practices regarding childhood influenza vaccination in Jiangsu showed moderate knowledge and positive attitudes but low actual vaccination rates, suggesting targeted interventions are needed to reduce the cognition-practice gap and improve childhood influenza vaccination coverage.
