Q&A: Modeling measles amidst a global disruption in vaccine supplies

Measles vaccination rates among children worldwide declined during the COVID-19 pandemic to the lowest level since 2008, likely due to lockdowns and difficulty accessing vaccines. According to a new report by the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) that published today (Nov. 17) in the CDC’s Morbidity and Mortality Weekly Report, this drop in vaccination coverage led to a 72% increase in reported measles cases and a 43% increase in measles deaths during 2021-22.
