Kiona Warren v. HHS - HPV, thrombotic thrombocytopenic purpura (2017)

Kiona Warren filed a petition alleging that the human papillomavirus (HPV) vaccine administered on September 17, 2010, caused her thrombotic thrombocytopenic purpura (TTP). Initially, the petition also claimed systemic lupus erythematosus (SLE) caused by the vaccine, but this claim was later removed.

Medical records indicate that Kiona began feeling unwell approximately 10-11 weeks after vaccination, with a low platelet count and hemoglobin. The respondent is the Secretary of Health and Human Services.

On October 4, 2017, Kiona Warren filed a Motion for Decision Dismissing Petition, stating she would be unable to prove entitlement to compensation and that proceeding further would waste resources. The court granted this motion, dismissing the petition.

The decision noted that to prove causation, a petitioner must demonstrate a medical theory connecting the vaccine and injury, a logical sequence of cause and effect, and a proximate temporal relationship, which Kiona Warren was unable to do. The case was dismissed on October 5, 2017.
