Dermatology · STI: HPV vaccine types

Sample item

Which HPV types are covered by the nonavalent vaccine?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. 6, 11, 16, 18, 31, 33, 45, 52 and 58

The nonavalent vaccine protects against types 6 and 11, which cause genital warts, and high-risk types 16, 18, 31, 33, 45, 52 and 58. The quadrivalent vaccine covers types 6, 11, 16 and 18, and the bivalent covers 16 and 18. Types 1, 2 and 4 cause common and plantar warts and are not included.

Option by option

  • A. 6, 11, 16, 18, 31, 33, 45, 52 and 58 (correct)

    Correct. This list matches the nonavalent vaccine.

  • B. 6, 11, 16 and 18 only

    That is the quadrivalent vaccine.

  • C. 16 and 18 only

    That is the bivalent vaccine.

  • D. 1, 2, 4 and 7

    Types 1, 2, 4 and 7 cause cutaneous warts and are not vaccine targets.
