Which vaccine can help prevent cervical cancer?

The vaccine that can help prevent cervical cancer is the Human papillomavirus (HPV) vaccine. This vaccine specifically targets the strains of HPV known to contribute to the development of cervical cancer, particularly HPV types 16 and 18. By immunizing individuals, the HPV vaccine significantly reduces the incidence of cervical cancer and other related genital cancers caused by these viral infections.

The HPV vaccine is especially recommended for preteens and young adults, as it is most effective when given before the onset of sexual activity. This proactive approach in vaccination can lead to a significant decrease in the prevalence of cervical cancer in the population, demonstrating the importance of vaccination in cancer prevention.

The other vaccines listed are important for protecting against their respective diseases—measles, hepatitis B, and varicella—but they do not have a direct role in preventing cervical cancer, making them irrelevant in this context. The focus on HPV in this question highlights its critical connection to cervical cancer prevention.
