A study led by the University of California, Riverside used survey data collected from April to December 2024 to examine gaps in measles-related knowledge and MMR vaccination among emergency department patients. The research, published in the American Journal of Emergency Medicine, included 2,459 adult patients from ten U.S. emergency departments and assessed MMR (measles, mumps, rubella) vaccination status, knowledge about measles and the vaccine, and willingness to be vaccinated.
Investigators found critical gaps: a substantial portion of patients lacked accurate knowledge, many were unsure of their vaccination status or reported not receiving the vaccine, and persistent hesitancy was driven by misconceptions about safety and necessity. Researchers also identified disparities tied to race, language, insurance status and access to primary care, which affect both access and health literacy.
Senior author Robert Rodriguez noted that emergency departments can act as safety nets by screening, providing education and referring patients to clinics and pharmacies for vaccination. The team recommended practical, low-burden steps to improve vaccination equity.
