“Measles used to be an extremely common disease. However, in 1963, John Enders developed the first effective measles vaccine. Vaccination efforts ramped up rapidly in richer countries, and in the 1970s and 1980s, they were scaled up worldwide. In just the last fifty years, it’s estimated that measles vaccinations have prevented over ninety million deaths worldwide. Two to three million people would die from measles every year without them.”From Our World in Data.
