The History of Measles: Discoverers, Origins, and the Evolution of Vaccines Through the Ages

Measles, or rubeola, has been humanity’s ancient foe for thousands of years. Before vaccines were discovered, measles was regarded as an unavoidable health threat for every child. Yet the long journey to understand and conquer this virus has involved the dedication of scientists across eras, from the Islamic Golden Age to modern laboratories in the United States.

Genetic research indicates that the measles virus (Measles virus) evolved from Rinderpest, a deadly cattle disease. Medical historians estimate that the species jump from cattle to humans occurred around the 6th century BCE, coinciding with increasing population density in ancient civilizations.

The figure who first managed to distinguish measles scientifically from other rash diseases was Muhammad ibn Zakariya al-Razi (865–925 CE). In his work Kitab al-Jadari wa-al-Hasbah, this Persian physician provides a highly accurate clinical description, noting that measles is more dangerous for the respiratory system than smallpox.

Although the symptoms have long been known, the causative agent of measles remained a mystery until the 20th century. Here are key milestones in the management of measles:

John Enders managed to attenuate the measles virus in the laboratory so that it could be used to stimulate the immune system without causing disease. In 1963, the first measles vaccine was officially licensed. This discovery led to a drastic reduction in measles mortality worldwide in the following decades.

Medically, Rhazes (al-Razi) was the first to define measles specifically as a disease distinct from smallpox in the 10th century.

The measles vaccine was first developed by John Franklin Enders in 1963.

Nevertheless, despite the availability of vaccines, measles continues to recur in regions with low vaccination coverage, with some case reports in 2026.

The history of measles stands as clear evidence of how science can transform a deadly threat into a preventable disease. From the sharp observations of Al-Razi to the laboratory technology of John Enders, the protection we have today is the legacy of thousands of years of medical research.
