Like I said, I understand why there is so much concern over Gardasil, and there is a lot of worrisome stuff out there, and I find Merk's marketing to be quite heavy handed and not entirely appropriate.
The fist link focuses on a girl whose symptoms began with a rash two months after the vaccine. So presumably she was fine for those two months? I guess it could possibly have been a delayed reaction to the vaccine. Or, the rash could have been an indication that she'd come down with a virus that triggered an autoimmune disease. That sounds more likely to me, but of course there is no way to know for sure.
The fourth one is Natalie Morton who died due to a large malignant tumor in her chest, basically a ticking time bomb which was ready to kill her at any moment, and that's when it went off.
The second could also have been a coincidence, though it sounds more likely to be related than the first. As for the third, I believe the CDC has had some concern about blood clots after Gardasil, though nothing conclusive and it's not listed as an official side effect. Sometimes blood clots just happen for unknown reasons, even in teens with no family history.
These are all anecdotes. Bad things happen to people unexpectedly all the time. With tens of millions of doses given, it is safe to assume that purely by chance some of those girls will have very bad things happen, even on occasion very rare bad things, occur soon after the shot. To determine that something is a real risk from Gardasil, anecdotes aren't enough, you need to know, for instance, how frequently blood clots happen in teens and if they are more common in teens who have just had Gardasil than in those who haven't.
And these are not isolated cases. This vaccine has now been banned by other countries like Spain and France because it takes the lives of healthy young girls.
