49 free Edward Jenner trivia questions with answers — science & nature quiz, new questions added Aug 2026.
This Edward Jenner trivia quiz covers the Gloucestershire country doctor whose cowpox experiment of 14 May 1796 gave the world its first vaccine and, in the end, wiped smallpox from the planet. It follows him from the vicarage in Berkeley and a boyhood variolation that damaged his health, through his apprenticeship under John Hunter in London ('Don't think; try'), his marriage to Catherine Kingscote and his surprising fame as a naturalist who worked out what baby cuckoos do to their nest-mates. Then comes the vaccine: milkmaid Sarah Nelmes, the cow Blossom, eight-year-old James Phipps, the Latin phrase that gave us the word vaccine, the 23 cases of the 1798 Inquiry, the parliamentary grants, the Balmis Expedition, Napoleon's medal, the 1840 ban on variolation, and the discovery that the modern vaccine virus is not cowpox at all. It finishes with Jenner's honours, his death in 1823 and the WHO's 1980 declaration that smallpox was gone. Every answer is checked against Wikipedia's articles on Jenner, smallpox and the vaccine, and each explanation adds one further fact. Ideal for science students, medical historians and anyone building a quiz round on great inventions.
