Michael Ibarra v. HHS - HPV, myalgias, joint pain, and telogen effluvium (2025)

On February 27, 2023, Michael Ibarra filed a petition alleging that HPV9 vaccines administered on February 27, 2020 and August 4, 2020 caused vaccine-induced myalgias, joint pain, and telogen effluvium within days. The public decision identifies him as an adult petitioner but does not state his exact age.

Mr. Ibarra filed medical records and affidavits, but respondent contested entitlement in a Rule 4(c) report.

Respondent argued that Mr. Ibarra had not provided preponderant evidence satisfying the Althen causation prongs, had not submitted an expert report, and had not produced reliable medical evidence connecting the HPV9 vaccinations to his alleged injuries.

The court set an expert-report deadline and granted three extensions, but no expert report was filed. After an order to show cause, Mr.

Ibarra moved to dismiss his petition. On October 28, 2025, Special Master Christian J.

Moran dismissed the case with prejudice for insufficient proof, finding that Mr. Ibarra had not proposed a medical theory causally connecting the vaccinations and alleged injuries and had not provided an expert report or other reliable causation evidence.

No compensation was awarded.
