What happens in this story4 scenarios
England, 1796. You hold a lancet and a theory that cowpox might prevent smallpox. The boy in front of you is eight years old. If you're wrong, you've just infected a child. If you're right, you change medicine forever.
What started with the cowpox gamble just got more complicated. Now you need to analyze historical medical decisions through ethical and practical lenses — and the situation is shifting faster than your first approach can handle.
This is the moment you've been building toward. Evaluating risk when the potential benefit could save millions of lives — except now the stakes are real and there's no rehearsal. What you do next matters.
You've faced the hardest part. Now turn what you've learned into something sustainable — a way to analyze historical medical decisions through ethical and practical lenses not just today, but every time this situation returns.
