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?
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.
The purpose of this study is to investigate the correlation of intention to receive COVID-19 vaccine, recommendation behavior, and 5C psychological antecedents among Nurses. The results can be used to assist suggestions in the health education provided by nurses on the topic of COVID-19 pneumonia and its vaccination. The purpose of the study is also wants to build a basis for future research and public support in vaccine decision-making, as well as to enhance the promotion of vaccine policy and enhance the resilience of the whole population during the pandemic ear.
A two-phases study will be carried out with the following aims 1. st phase (2018-2020) - To investigate the vaccination coverage for Rotavirus vaccine (RV) in Campania Region together with other pediatric vaccinations scheduled in the first 12 months of life: hexavalent, pneumococcal conjugate (PCV), meningococcal B (MenB) - To collect data on appropriate timing of the 3 doses of human bovine pentavalent reassortant vaccine (RV5) administration - To evaluate the frequency of a co-administration of RV5 with other vaccines scheduled in the first 12 months of life (hexavalent/PCV+RV5, MenB+RV5 vs RV5 alone) and assess the variability in co-administration rates according to RV5 dose 2. nd phase (2020-2022) - To investigate the effect of Coronavirus-Disease-19 (COVID-19) pandemic on vaccination coverage in the first year of life, focusing on RV vaccination - To investigate the effect of COVID-19 pandemic on timing of vaccine administration in the first year of life, focusing on those vaccines without catch-up vaccination schedule (i.e. RV) Hypothesis are the following: - Vaccination coverage and timing of vaccines scheduled in the first year of life are not fully aligned with what is established by the Italian National Prevention Plan 2017-2019 - Co-administration of RV5 and MenB in comparison with other coadministration e.g. hexavalent/PCV is lower - Co-administration of RV5 and MenB allows to ensure appropriate timing of RV vaccination schedule - COVID-19 pandemic may have affected the overall vaccination coverage as well as the timing of selected vaccination scheduled in the first year of life, with a more relevant impact on vaccines for whom a catch-up vaccination schedule is not feasible, such as RV immunization.
