Hepatitis C has all of the following characteristics EXCEPT:
Show answer and explanation
Correct answer: C. A vaccine is available to prevent it
- A. HCV is indeed transmitted primarily through blood (sharps, needles, blood exposure) — a true statement.
- B. Many people carry HCV asymptomatically for years/decades before complications — a true statement.
- C. Correct (the EXCEPT). There is NO vaccine for hepatitis C (its high genetic variability has prevented one). Contrast with hepatitis B/A, which DO have vaccines — a frequently tested distinction. HCV is, however, now curable with direct-acting antivirals.
- D. Chronic HCV can lead to cirrhosis and hepatocellular carcinoma — a true statement.
Note: The source's option list for the 'except' was incomplete; the standard, board-tested EXCEPT here is the absence of an HCV vaccine.
