i would personally doubt an hpv vaccine connection but it is natural for people to blame the last thing that may have been done prior to the adverse event. call the company that makes the hpv vaccine. many will have a medical consultant that will speak with you. you can also contact the cdc. there is a section on vaccine adverse events.
wondering how someone could find out if the hpv vaccine series might be the cause of onset of grand mal seizures. daughter received the series of vaccines between 14-15. had her first grand mal seizure august 2012 at the age of 15 years 9 months had a small seizure in september 2012 had another grand mal november 7 2013 at the age of 16 years. they can find no cause of the seizures. they have run two eeg exams and completed a brain mri. all showed nothing to determine cause or area of seizures.
