Which HPV vaccine provides protection against the greatest number of oncogenic HPV types?
- A Bivalent vaccine (HPV 16, 18)
- B Quadrivalent vaccine (HPV 6, 11, 16, 18)
- C Monovalent vaccine (HPV 16)
- D Nonavalent vaccine (HPV 6, 11, 16, 18, 31, 33, 45, 52, 58) ✓
Correct answer: D. Nonavalent vaccine (HPV 6, 11, 16, 18, 31, 33, 45, 52, 58)
Explanation
The nonavalent HPV vaccine protects against nine HPV types: 6, 11, 16, 18, 31, 33, 45, 52, and 58. It covers the two most common oncogenic types (16 and 18) plus five additional high-risk types (31, 33, 45, 52, 58), providing protection against approximately 90 percent of cervical cancers. The bivalent and quadrivalent vaccines cover fewer oncogenic types.
