More Than 4 in 10 Adults Not Up to Date on Measles Vaccine

A study published in the American Journal of Emergency Medicine found that 44.0% of adults surveyed in US emergency departments were not up to date on their measles, mumps, and rubella (MMR) vaccination. The researchers suggested that emergency departments could be used to deliver accessible public health interventions and improve vaccine equity.
A study published in the American Journal of Emergency Medicine assessed adult MMR vaccination status and willingness to receive vaccination in emergency departments. The analysis included survey responses from 2456 adults treated at one of 10 US emergency departments from April to December 2024. The researchers found that 25.0% of respondents had not heard of the MMR vaccine and 44.0% were not up to date. Being unvaccinated was associated with male sex, non-Hispanic African American race, Hispanic ethnicity, non-English speakers, and not having primary care access. More than one-third of those who were not up to date (36.5%) were willing to receive an MMR vaccine in the emergency department. The study suggests that emergency departments can be used to improve vaccine equity.
