POTS, like most diagnoses, does not have an identifiable cause according to most cardiologists. Until now. A new study linking the HPV vaccine to POTS has just been published in the very pro-vaccine journal Vaccine. Perhaps even more concerning than POTS is the observation that "irregular periods were reported by all patients not on treatment with oral contraception." Previously published case studies have shown a link between the HPV vaccines and “Primary Ovarian Failure,” or premature menopause.
