Gardasil 9 covers which HPV genotypes?

• A. 6,11,16,18
• B. 6,11,16,18,31,33
• C. 16,18,31
• D. 6,11,16,18,31,33,45,52,58

Answer: (D)

Gardasil 9 is a nine-valent HPV vaccine that provides protection against nine genotypes known to cause disease. It retains protection against the two common cancer-causing types (16 and 18) and the two wart-causing types (6 and 11), and adds protection against five additional high-risk types: 31, 33, 45, 52, and 58. Because it includes all nine genotypes, it offers broader coverage than vaccines that protect only a subset of these. That’s why the option listing all nine genotypes—6, 11, 16, 18, 31, 33, 45, 52, 58—is the correct choice. The other options omit one or more of these genotypes.
