Is there a cure for tetanus?

• A. Yes, antibiotics cure
• B. Vaccination is curative
• C. No, but there is a vaccine
• D. Tetanus is always fatal

Answer: (C)

The key idea here is the distinction between curing an established tetanus infection and preventing it with vaccination. Tetanus is caused by a toxin that stops inhibitory signals in nerves, leading to severe muscle spasms. Once this toxin has bound to nerves, antibiotics won’t reverse the damage, so there isn’t a true cure for the disease itself. Treatments can reduce toxin production, neutralize any toxin still circulating with tetanus immune globulin, clean the wound, and provide supportive care, but the existing toxin’s effects aren’t reversed by medication alone. The only way to prevent tetanus is immunity from vaccination, which primes the immune system to neutralize the toxin before it causes disease. So the best statement is that there is no cure, but there is a vaccine.
