Is there a vaccine to prevent Hepatitis C (HCV)?

• A. Yes
• B. No
• C. Only in development
• D. Only in some countries

Answer: (B)

There isn’t an approved vaccine to prevent Hepatitis C right now. HCV presents a moving target for vaccines because it has many genotypes and mutates frequently, so the virus can change enough to evade immune responses. An effective vaccine would need to provide broad protection across all genotypes, and despite years of research with approaches aiming to trigger strong antibodies or robust T‑cell responses, none have shown durable, universal protection in diverse populations. So, at present, prevention relies on avoiding exposure and using safe practices, along with diagnosing and treating infections with highly effective antiviral therapies. Vaccines for Hepatitis A or B exist, but not for Hepatitis C.
