Factors that affected Penicillin
Chance
It was by chance that Alexander Fleming discovered penicillin
Chance that Fleming was observant and saw the mould
Chance that Fleming published his findings in a book, which laid the pathway for Chain & Floery's tests.
It was also luck/chance that Penicilin bacteria happened to have medical properties and Flemming saw that,
Fleming wasn't able to continue his work on penicillin, which without that Florey and Chain's discoveries, tests and developments wouldn't have happened.
Government
The US and UK government paid large amounts of money to help mass produce the drug.
Without this aid, penicillin wouldn't have reached lots of people or saved load of lives both in WW2 and after this time.
Fleming didn't research more into Penicillin because of war and lack of funding.
Florey and Chain worked on penicillin because they loved science and weren't phased by war as much as Fleming.
Florey and Chain gained money from the war board (part of the government) in order to support their developments and testing of penicillin.
If the world hadn't gone to war again, government wouldn't have poured money into the development and mass production of penicillin.
British government funded Florey's research in 1939
US government gave drug companies $80 million in 1942 to start mass production of penicillin
Science & Technology
Florey and Chain used a mix of new methods and old ones to produce penicillin.
They made use of new technology such as freeze-drying
They also used older/more traditional methods such as thousands of milk bottles, milk churns and hand pumps.
Florey and Chain were talented scientists who developed penicillin, tested it, proved it worked and then led it to mass production after WW2.
Proving it worked by injecting mice with microbes, some would be given penicillin as well. 24 hours later, they would view the results.
War
WW2 rapidly helped the development of penicilin.
Led to penicillin being tested on Albert Alexander (a police officer) and the pair proved it to be somewhat a success, but it worked.
Led to the US and UK governments had invested in buying penicillin
15% of people/soldiers with infected injuries during WW2 had been saved by penicillin.
Mass production after WW2 of penicillin started because it is high in demand.
Fleming didn't research more into Penicillin because of war and lack of funding.
Florey and Chain worked on penicillin because they loved science and weren't phased by war as much as Fleming.
If the world hadn't gone to war again, government wouldn't have poured money into the development and mass production of penicillin.
Key individuals
Florey and Chain developing and testing Penicillin
If Florey and Chain were not interested in Fleming's work, penicillin may have been developed a lot more slowly.
Alexander Fleming because he discovered penicilin and it's medical perperties, even if it was by accident.
If Fleming hadn't told people about his discovery or ignored the mould, penicillin may have been discovered much later, or not at all.
Team of researchers who helped develop penicillin because they helped Florey and Chain with their discoveries
The war board since they gave Florey, Chain and their researches £25 to work on their discoveries/on penicillin. This helped the to carry on with Fleming's work.
Communication
WW2 led to more communication between countries
Fleming published his findings on penicillin in a book which intrigued Chain and Florey to look into it and developing it even more.
Development of the drug was undertaken by 4 major drug companies.
