Which of the following vaccines is likely to decrease the risk of developing cancer?

• A. HPV vaccine
• B. Polio vaccine
• C. MMR vaccine
• D. Influenza vaccine

Answer: (A)

Verified step by step guidance

1. Understand the relationship between certain viruses and cancer. Some viruses, such as the Human Papillomavirus (HPV), are known to increase the risk of developing specific types of cancer, such as cervical cancer, anal cancer, and throat cancer.
2. Review the purpose of each vaccine listed: The HPV vaccine is specifically designed to protect against strains of HPV that are linked to cancer. The Polio vaccine prevents polio, the MMR vaccine prevents measles, mumps, and rubella, and the Influenza vaccine prevents the flu. None of these other vaccines are directly linked to cancer prevention.
3. Recognize that the HPV vaccine is unique among the options because it directly targets a virus known to cause cancer, thereby reducing the risk of developing cancer associated with HPV.
4. Consider the broader public health impact of the HPV vaccine. By reducing the prevalence of high-risk HPV strains in the population, the vaccine contributes to a lower overall incidence of HPV-related cancers.
5. Conclude that the correct answer is the HPV vaccine, as it is the only vaccine in the list that is specifically associated with reducing the risk of developing cancer.
