Charles Richet was awarded Nobel Prize in Physiology or Medicine for his seminal discovery of
Show Hint
- immunoglobulins
- hypersensitivity
- mRNA vaccines
- malaria vaccine
The Correct Option is B
Solution and Explanation
Step 1: Understand his contribution.
• Studied immune response to toxins
• Discovered exaggerated immune reactions
• Named it anaphylaxis (hypersensitivity)
Step 2: Analyze options.
• Immunoglobulins → discovered later by others
• Hypersensitivity → correct
• mRNA vaccines → modern discovery
• Malaria vaccine → recent development
Step 3: Final conclusion.
Thus, the correct answer is: \[ Hypersensitivity \]
