Vaccine Refusal

Achieving optimal vaccination rates is vital for protecting the health and well-being of all individuals. This specific study focuses on the MMR and RSV vaccines in pregnancy and early childhood, which have been shown to reduce RSV and MMR-related illnesses, hospitalizations, and deaths. Efforts to improve vaccination rates have not been equally effective across the entire population; this has resulted in poorer outcomes from interventions for certain populations who are vaccine-hesitant. This study seeks to understand how to best increase vaccine confidence in marginalized populations. To do this, the investigators will interview parents of children who receive care at Boston Medical Center (BMC), Community Health Workers and other Clinical providers at BMC, leading experts in the fields of vaccine confidence and implementation science, and key public health stakeholders/officials.

The goal of this project is to establish the technical feasibility of a scalable, integrated platform to improve patient informed decision-making and increase vaccine uptake and to evaluate the effectiveness of the integrated platform to improve vaccine uptake.

This study aims to evaluate the impact of active health education methodologies on increasing adherence to the HPV vaccine among schoolchildren. The project will involve 196 schools across Brazil, encompassing a total of 5,000 students. A stepped-wedge implementation design will be applied, with clusters being randomized every two months to one of four interventions. Each intervention will be implemented in 48 schools.

The goal of this observational study is to learn about vaccinations hesitancy, delay or avoidance in children with chronic diseases, congenital anomalies or disabilities. The main questions it aims to answer are: • Attitudes of caregivers towards vaccinating their children, obstacles that postpone vaccinations, and the status of vaccinations of these children. Participants will fill out questionnaires and some will be included in focused groups for the qualitative part of the study. Researchers will compare the vaccinations status of the research group to their siblings' status as well as the published national records of vaccination compliance.

The objective of this study is to investigate vaccination acceptance and identify the reasons why people are not vaccinated. People over 18 years of age who live in neighborhoods with socioeconomic vulnerability and with many cases of infectious diseases, as well as health professionals, will respond to a research questionnaire.
