Why did Fleming not develop and mass produce penicillin?

• A. Lack of interest
• B. Government restrictions
• C. Lack of funding
• D. Scientific uncertainty

Answer: (C)

The key idea is that turning a laboratory discovery into a widely used medicine requires substantial resources to scale up production. Fleming identified penicillin’s potential, but making it in the quantities needed for medical use demanded large-scale fermentation, purification, quality control, and the infrastructure of industry and trials. He didn’t have the funding or the industrial backing to push penicillin from a breakthrough into a mass-produced drug. Later, with the help of government support and industrial funding led by Florey, Chain, and others, penicillin was produced on a massive scale during the war. So, the best answer points to lack of funding as the main barrier. The other options don’t fit as well because Fleming’s interest wasn’t the central issue, there were no outright government restrictions stopping him, and while scaling posed challenges, the decisive obstacle was securing financial backing.
