Gardasil (HPV Vaccine) Safety in Pregnancy

Official Recommendation

Gardasil (including Gardasil 9) is not recommended during pregnancy due to limited safety data. This is a precautionary stance, not a contraindication based on demonstrated harm (rated CIII — expert opinion, limited data).

What the Evidence Actually Shows

Despite the recommendation against use, available data are reassuring:

Study / Source	Finding
Combined analysis of 5 RCTs (HPV 6/11/16/18 quadrivalent vaccine)	Vaccine administration during pregnancy did not negatively affect pregnancy outcomes
Denmark population-based study (~5,200 pregnancies, quadrivalent vaccine)	No increased risk of spontaneous abortion, stillbirth, or infant mortality
Denmark Medical Birth Register (1,665 exposed pregnancies)	No significantly increased risk of major birth defects, preterm birth, or low birth weight
9-valent (Gardasil 9) data	More limited but also reassuring to date

Key Clinical Points

Pregnancy testing is not required before vaccination.
If inadvertently given during pregnancy, no intervention is needed — simply defer any remaining doses until after delivery.
The vaccine series should be paused and completed postpartum.
The recommendation against use is precautionary, not because harm has been demonstrated.

Bottom Line

Gardasil is not approved for use in pregnancy, but inadvertent exposure carries no known fetal risk based on current evidence. Any remaining doses in a series should be deferred until after delivery. Women who receive a dose before realizing they are pregnant can be reassured that studies have not shown adverse pregnancy outcomes.
