Dermatology · STI: HPV vaccine types
Sample itemWhich 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.
