(Human Papillomavirus 9-valent Vaccine, Recombinant)
Suspension for intramuscular injection
Initial U.S. Approval: 2014
6.2 Postmarketing Experience
The postmarketing adverse experiences were reported voluntarily from a population of uncertain size,
therefore, it is not possible to reliably estimate their frequency or to establish a causal relationship to vaccine
exposure.
The safety profile of GARDASIL 9 and GARDASIL are similar. The postmarketing safety experience
with GARDASIL is relevant to GARDASIL 9 since the vaccines are manufactured similarly and contain the
same L1 HPV proteins of four of the same HPV types.

have been spontaneously reported during post-approval use of GARDASIL 9:
