Filter by: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.
Subjects will be recruited and divided into 3 groups: 1. Hepatitis A（Live）Vaccine，Freeze-dried produced by Changchun Institute of Biological Products Co., Ltd 2. Hepatitis A（Live）Vaccine，Freeze-dried produced by Zhejiang Pukang Biotechnology Co., Ltd., and 3. Hepatitis A（Live）Vaccine，Freeze-dried produced by Institute of Medical Biology, Chinese Academy of Medical Sciences. After immunization, the immunogenicity and safety of three different manufacturers will be compared and the data will be analyzed.
Most adolescents who receive human papillomavirus (HPV) vaccine are vaccinated in pediatric practices, yet missed opportunities (MOs) for HPV vaccination occur often and lead to low HPV vaccination rates. This single-arm study (embedded within arm 2 of a 2-arm cluster randomized clinical trial (RCT)) will test the effectiveness (and cost-effectiveness) of a bundled intervention (HPV vaccine communication, performance feedback reports and provider prompts), in practices that previously received standard of care, to reduce MOs and increase HPV vaccination rates.
Most adolescents who receive human papillomavirus (HPV) vaccine are vaccinated in pediatric practices, yet missed opportunities (MOs) for HPV vaccination occur often and lead to low HPV vaccination rates. This study is part of a series of cluster randomized clinical trials (RCTs) that will test the effectiveness (and cost-effectiveness) of the addition of prompts (period 3) to performance feedback (period 2, continued through period 3) and training providers previously received on HPV vaccine communication (period 1) to reduce MOs and increase HPV vaccination rates.
