What is the role of the HPV vaccination in adolescence?

• A. It prevents all STIs.
• B. It cures existing HPV infections.
• C. Provides protection against human papillomavirus infections that can lead to cervical cancer; part of STI prevention.
• D. It is only for adults.

Answer: (C)

Preventive immunization in adolescence aims to reduce future risk of disease caused by HPV by training the immune system to recognize the high‑risk HPV types most likely to cause cancer. The vaccine targets the strains most strongly linked to cervical cancer and other cancers, and it also protects against strains that cause genital warts. It works best when given before exposure to the virus, which is why it’s recommended during the teenage years. It does not cure existing HPV infections, and it does not protect against all sexually transmitted infections. By lowering the chances of HPV infection, it plays a key role in STI prevention and long-term health, and it’s not limited to adults.
