Background: Sporadic outbreaks of COVID-19 remain a threat to public healthcare, especially if vaccination levels do not improve. As Malaysia begins its transition into the endemic phase, it is essential to identify the key determinants of COVID-19 vaccination intention amongst the pockets of the population who are still hesitant. Therefore, focusing on a sample of individuals who did not register for the COVID-19 vaccination, the current study integrated two widely used frameworks in the public health domain-the health belief model (HBM) and the theory of reasoned action (TRA)-to examine the inter-relationships of the predictors of vaccination intention amongst these individuals.
Methodology: Primary data from 117 respondents who did not register for the COVID-19 vaccination were collected using self-administered questionnaires to capture predictors of vaccination intention amongst individuals in a Malaysian context. The partial least squares structural equation modeling (PLS-SEM) technique was used to analyze the data.
Results: Subjective norms and attitude play key mediating roles between the HBM factors and vaccination intention amongst the unregistered respondents. In particular, subjective norms mediate the relationship between cues to action and vaccination intention, highlighting the significance of important others to influence unregistered individuals who are already exposed to information from mass media and interpersonal discussions regarding vaccines. Trust, perceived susceptibility, and perceived benefits indirectly influence vaccination intention through attitude, indicating that one's attitude is vital in promoting behavioral change.
Conclusion: This study showed that the behavioral factors could help understand the reasons for vaccine refusal or acceptance, and shape and improve health interventions, particularly among the vaccine-hesitant group in a developing country. Therefore, policymakers and key stakeholders can develop effective strategies or interventions to encourage vaccination amongst the unvaccinated for future health pandemics by targeting subjective norms and attitude.

India's National COVID Vaccination Program recommended vaccination of children ages 6-12 years in April 2022. This study assessed vaccine acceptance among mothers to better understand potential barriers and facilitators of national acceptance of pediatric coronavirus disease 2019 (COVID-19) vaccination. Qualitative data were collected through three focus group discussions (FGDs) with mothers who had children younger than 12 years of age; FGD-1 was composed of mothers who worked at a tertiary medical center in India, whereas FGD-2 and FGD-3 were composed of mothers who sought care at urban and rural community health centers.

Preventive interventions are expected to substantially improve the prognosis of patients with primary liver cancer, predominantly hepatocellular carcinoma (HCC) and cholangiocarcinoma. HCC prevention is challenging in the face of the evolving etiological landscape, particularly the sharp increase in obesity-associated metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD). Next-generation anti-HCV and HBV drugs have substantially reduced, but not eliminated, the risk of HCC and have given way to new challenges in identifying at-risk patients.

College students are important targets for the influenza vaccine given this population's low vaccination rates; however, limited research has focused on international college students' vaccination status. This study examined the relationships between the theory of planned behaviour (TPB; attitudes, perceived behavioural control (PBC) and subjective norms) and students' intention of receiving an influenza vaccine.

These innovations could support regions in accelerating malaria control, transforming existing intervention packages by supplementing interventions with imperfect effectiveness or offering an entirely new tool. However, to layer new medical tools as part of an existing programme, malaria researchers must come to an agreement on the gaps that currently limit the effectiveness of medical interventions for moderate to low transmission settings.

Introduction: Human Papillomavirus (HPV) vaccine uptake in the French Caribbean has remained below 25% since introduction in 2007, which is well behind national and international targets. Using a discrete choice experiment (DCE), we explored parental preferences around HPV vaccination and optimized communication content in a sample of parents of middle-school pupils in Guadeloupe.
Methods: We conducted a cross-sectional survey in public and private middle age schools in Guadeloupe in June 2023 using an online questionnaire.
