Penicillin was first tested on humans in what year?

Explanation:
The key point is when penicillin first moved from lab work to testing in people. After Fleming’s 1928 discovery, it took until 1941 for scientists to purify the compound and develop methods to produce it in usable quantities. In early 1941, the first human trial was carried out in London, treating a patient with a severe infection. The treatment showed clear improvement, though supplies were limited and eventually ran out, and the patient died later. Nevertheless, this trial proved penicillin could save lives and spurred large‑scale production. So the year penicillin was first tested on humans is 1941.
