One physician's assistant reported that a female patient "died of a blood clot three hours after getting the Gardasil vaccine." Two other reports, on girls 12 and 19, reported deaths relating to heart problems and/or blood clotting.
Of the 1,637 adverse reactions to Gardasil reported to the FDA since the drug was on the market, there were 371 serious reactions. Of the 42 women who received the vaccine while pregnant, 18 experienced side effects ranging from spontaneous abortion to fetal abnormalities.
However, 1367 adverse reactions out of million of doses given is a really small percentage. You would get a higher negative reaction rate from aspirin, and much higher from penicillin.
