Unravelling the Measles Paradox in Children

Sponsor: Erasmus Medical Center

Summary

Measles is caused by measles virus (MeV). The disease is associated with lymphopenia and immune suppression, which is an important cause of measles-associated morbidity and mortality. Measles-induced immune suppression can last several years, whereas measles lymphopenia is usually resolved within two weeks. At the same time, measles induces lifelong immunity. This apparent contradiction, known as the 'measles paradox', was partially solved when investigators demonstrated that MeV infects and depletes pre-existing memory cells, thereby causing 'immune amnesia'. This model is supported by observations in animal models and clinical studies, but several questions remain to be addressed, like the duration of measles-induced amnesia and changes in the immune repertoire after measles. to address the immunological questions regarding MeV infection.
