Medical Discoveries Quiz – Breakthroughs That Saved Lives

Medicine changed dramatically over the last 250 years. Edward Jenner's smallpox vaccine, Ignaz Semmelweis's handwashing and Joseph Lister's antiseptic surgery showed that preventing infection could save countless lives, even before germs were fully understood.

In the late 1800s, Louis Pasteur and Robert Koch proved that microbes cause disease. Röntgen's X-rays let doctors see inside the body, Landsteiner's blood groups made transfusions safe and anesthesia made surgery bearable. Each discovery built on earlier ones.

The 1900s brought insulin, antibiotics like penicillin, polio vaccines and the discovery of DNA's structure. Smallpox was eradicated in 1980. Today, gene therapies, mRNA vaccines and medical imaging continue this long story of discovery.
