Brief summary

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.
