Which vaccine reduces the risk of cervical cancer?

• A. Hepatitis B vaccine
• B. Influenza vaccine
• C. HPV vaccine
• D. Meningococcal vaccine

Answer: (C)

HPV vaccination reduces cervical cancer risk by preventing infection with high‑risk human papillomavirus types that cause the majority of cervical cancers. By generating antibodies before exposure, the vaccine prevents persistent HPV infection and the development of precancerous cervical lesions that can progress to cancer. It works best when given before individuals become sexually active, and many formulations cover multiple high‑risk HPV types, broadening protection. The other vaccines protect against diseases unrelated to cervical cancer (for example, hepatitis B vaccine lowers liver cancer risk, influenza vaccine prevents flu, meningococcal vaccine prevents meningitis), so they do not reduce cervical cancer risk.
