Washington University School of Medicine in St. Louis is the clinical coordinating center for an international trial aimed at evaluating on a large scale whether the MMR vaccine can protect against COVID-19.
The study will recruit front-line health-care workers, including those from lower- and middle-income countries. The countries involved include Canada, Ghana, Ireland, South Africa, Uganda, United Kingdom, United States, Zambia and Zimbabwe. In many of those nations, there are relatively few health-care workers per capita, and protecting them from severe COVID-19 infection could provide a substantial public health benefit and help reduce community spread of the virus.
