Letter: Need for worldwide health care

Sir: The caption to the attractive photographic portrait of Sir Alexander Fleming ("The waning of the antibiotic age", 21 May) might have mentioned that the Nobel Prize was shared with Chain and Florey. A distinguished pathologist once summed up the contributions of those three scientists thus: "Without Fleming there would have been no Chain, without Chain there would have been no Florey, without Florey there would have been no penicillin".
