Filter by:The goal of the study is to monitor and evaluate the implementation of interventions that aim to increase HPV & MMR vaccines among underserved communities across four European countries: Greece, Netherlands, Poland, and Slovakia. The interventions will target identified health systems barriers in an earlier phase of the project. The interventions that will be implemented employ trusted community members as health promotors whom will provide educational sessions on HPV and MMR vaccination to the target groups. In addition, the cost-effectiveness of vaccine uptake strategies for the target groups is being evaluated. The main research question is: to what extent is the multicomponent tailored intervention effective to increase MMR/HPV intention and vaccine uptake in the target population in Greece, Netherlands, Poland and Slovakia?
The objective of this randomized, multicenter, open-label, parallel, controlled clinical trial is to evaluate pain reduction during the administration of two vaccines in children aged 3 and 6 years through virtual reality. The main question[s] it aims to answer are: 1. To evaluate the reduction in pain during the administration of two vaccines in children aged 3 and 6 years. 2. To evaluate the reduction in anxiety during and after the administration of two vaccines in children aged 3 and 6 years. 3. Improve the satisfaction of parents or legal guardians after the administration of two vaccines in children aged 3 and 6 years. 4. Evaluate the Safety of the use of virtual reality glasses in children aged 3 and 6 years during the administration of vaccines. The study population will include children aged 3 and 6 years who are included in the patient registry and are being seen in a primary care center of the Catalan Institute of Health in Central Catalonia. The clinical trial has two assigned groups: a control group and an intervention group. The intervention group will use the Pico G2 VR goggles (Pico Interactive Inc) during the administration of the two vaccines, together with an Android AOYODKG tablet, which will be connected to the goggles as a controller. The control group participants will receive traditional distractors, such as being held by the parent or guardian who accompanies them to the appointment, receiving stickers at the end of the appointment, or receiving rewards that the parent or guardian has prepared from home.

The hepatitis A virus (HAV) is a significant global public health concern. The hepatitis A virus is transmitted primarily by the faecal-oral route, leading to acute hepatitis. Symptoms include low-grade fever, anorexia, jaundice, and typically resolve without complications. However, HAV infection in patients with chronic liver disease, especially those over 50 years old, may result in more severe outcomes, including fulminant hepatitis, with a higher mortality rate compared to the general population HAV vaccination is a cornerstone of prevention, especially in high-risk groups. Currently, there is a recommendation to vaccinate patients with chronic liver disease against HAV infection. However, these patients often have compromised immune responses, leading to lower vaccine efficacy compared to the general population. The goal of this randomized controlled trial is to compare the efficacy and safety of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen with an intensive 3-dose (0, 1, 6 months) schedule in patients with advanced fibrosis and cirrhosis. The main questions it aims to answer are: - Compared the seroconversion rate of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis. - Compared the antibody levels against the hepatitis A virus (Anti-HAV IgG) of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis.
A prospective, open-label and parallel non-randomized control trial and biomarker research study is intended to compare incidence of repeated COVID-19 infection, severe pneumonitis and mortality between lung cancer patients undergoing systemic antitumor therapies who get vaccinated with 1 booster dose(majorly against XBB) and those who refuse. Meanwhile, a biomarker research is designed to monitor serum level dynamics of specific antibodies against COVID-19,analyze its correlation with incidence of breakthrough infection and further explore optimal periods for vaccination.
The goal of this cluster, randomized controlled trial is to study the impact of mobile vaccine clinics and religious conferences on pediatric vaccination coverage. The main questions will be: does vaccination coverage change in geographic areas with the mobile vaccine clinics vs those areas without mobile vaccine clinics; and does vaccination coverage change in geographic areas with religious conferences on vaccination vs those areas without religious conferences. In repeated surveys, adult participants will respond about their children's vaccination status. Participants will not be individually randomized to the interventions. Rather, their geographical area will be randomized.
Background and Objective: Tanzania is one of 20 countries where the majority of un- and under-vaccinated children reside. Prior research identified substantial rural-urban disparities in rates and timeliness of childhood vaccination in Tanzania, with children in rural settings being more like to receive delayed or no vaccinations. This type 1 effectiveness implementation hybrid study will evaluate the effect of Chanjo Kwa Wakati ("Timely Vaccination" in Kiswahili), a community-based, integrated digital health intervention, on vaccination timeliness. The intervention combines a vaccination knowledge intervention, mobile phone-based reminders, and incentives with the goal to promote timely childhood vaccinations. Methods: The study will be conducted in two predominantly rural regions in Tanzania with high numbers of un- or under-vaccinated children. Forty rural health facilities and their catchment areas ("clusters") will be randomized to an early or delayed onset study arm. From each cluster, three cohorts of mother-child dyads, one retrospective cohort and two prospective cohorts, will be enrolled into the study. For all vaccines due during the first year of life, timeliness (primary outcome) and coverage (secondary outcome) will be observed for 1200 children (600 intervention children and 600 non-intervention children). Study logs, fidelity checklists, quantitative surveys, vaccination records, and qualitative interviews with mothers and key informants will be used to inform the five constructs of the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework. Results will be used to develop an implementation blueprint that can guide future adaptations, sustainability, and scale-up of Chanjo Kwa Wakati. Hypothesis: The hypothesis is that Chanjo Kwa Wakati is effective for increasing the timeliness of childhood vaccinations due by age 1 year compared to the standard of care. Expected impact: This study will address the lack of rigorous evidence on the effectiveness of an community-based digital health intervention for promoting vaccination coverage and timeliness among children from sub-Saharan Africa, and identify implementation strategies to facilitate the deployment of integrated vaccination interventions in low- and middle-income country settings.
Background: In Bangladesh, seasonal influenza imposes considerable health and economic burden, particularly for those at high risk of severe disease. To prevent influenza and lessen the economic burden, despite the World Health Organization's (WHO) recommendation of seasonal influenza vaccination prioritizing high-risk groups, many low-income countries, including Bangladesh, lack a national policy/programme and relevant statistics on seasonal influenza vaccination. Objectives: 1. To determine influenza vaccine acceptability, health beliefs, barriers, and intention of receiving influenza vaccine among targeted high-risk populations 2. To determine the cost-effectiveness of a seasonal influenza vaccination targeting high-risk populations during visits to health facilities for routine care 3. To investigate the required capacity for a potential seasonal influenza vaccination programme targeting high-risk populations during their visits to health facilities for routine care Methods: The study will be conducted in three hospitals' inpatient and outpatient departments with ongoing hospital-based influenza surveillance (HBIS). To meet objective 1, the investigators will collect quantitative data on participants' acceptability, health beliefs, barriers, and vaccination intentions using the health belief model (HBM) from patients meeting criteria for high-risk populations attending two public tertiary-level hospitals. To meet objective 2, in one of the two hospitals, the investigators will run an influenza vaccination campaign before the influenza season (the vaccines will be in the southern hemisphere), where the vaccine will be offered free of cost to high-risk patients, and in the second hospital, vaccination will not be offered. Both the vaccinated and unvaccinated participants will then be followed-up for one year period once a month to record any influenza-like illness, hospitalization, and death. Additional data for objective two on direct and indirect costs associated with influenza illness will be collected from patients with influenza-like illness (ILI) and severe acute respiratory infections (SARI) at one public and one private hospital. To meet objective 3, the investigators will estimate the required number of influenza vaccines, safe injections, and total storage volume utilizing secondary data. The investigators will use a deterministic Markov decision-analytic model to estimate the cost-effectiveness of facility-based vaccination in Bangladesh.
The goal of the study is to determine the effect of a communications campaign sharing wastewater surveillance data to influence vaccine uptake in a metropolitan and non-metropolitan environment. The study will be conducted in Onondaga and Cayuga counties in New York State. Individuals of all ages within the selected counties, located in metropolitan and non-metropolitan environments will receive the intervention. The evaluation study design is a comparison-control trial. The primary outcome measure is the proportion of vaccine-eligible individuals in the county that received the COVID-19 vaccine stratified by type of vaccine dosage and age group. Vaccination data will be aggregated to the county by the State Department of Health and shared with the research team. Wastewater data will be pulled from the wastewater surveillance network. A difference in differences analysis will be used to estimate the effect of the intervention on both the outcomes between intervention and comparison groups following the intervention, while adjusting for potential confounding factors.
The goal of this clinical trial is to test the effect of telehealth service provided to pregnant women about childhood vaccines on vaccine attitudes and vaccination. The main questions it aims to answer are: - Does telehealth service provided to pregnant women about childhood vaccines decrease the mean scores of the vaccine attitudes scale? - Does telehealth service provided to pregnant women about childhood vaccines increase the vaccination? In the intervention group, researchers will send educational materials (video and e-brochures) about childhood vaccinations to the participants' mobile phones at regular intervals, answer their questions over the phone and send reminder messages before the vaccination appointment. In the control group, there will be no information or intervention about childhood vaccines by the researchers, and standard procedure will be followed. Researchers will compare the intervention and control groups to see if there is a difference between vaccination attitudes and vaccination rates.
The study is aimed at the clinical and laboratory characteristics of patients with completed vaccination against SARS-CoV-2 admitted to the hospital in the standard ward and intensive care unit due to the severe course of COVID-19.
