Smallpox, caused by the variola virus, is one of the most devastating human diseases. Smallpox killed millions of people but drove Edward Jenner’s invention of vaccination, which eventually led to the annihilation of the virus, declared in 1980. To investigate the history of smallpox, an international team of researchers led by University of Cambridge and University of Copenhagen scientists sequenced and analyzed DNA from 1,867 humans who lived...
