Sherri Tenpenny: The Magnet, the Boot Camp and the Canadian Connection

An Ohio osteopath who once ran a hospital emergency department became one of the most-quoted anti-vaccine voices in the world. She sells a $623 course on how to talk people out of vaccines, told legislators the COVID shot could magnetize them, lost her licence for refusing to cooperate with the regulator, let it expire after getting it back, and now owes the U.S. government nearly $700,000 in taxes. Canadian groups are still quoting her.

1. Who she is

The record before the activism

Somewhere along the way the emergency physician became a vaccine opponent. By the mid-2000s she was writing books against vaccination and speaking on the alternative-health circuit. Her own speaker material, as compiled by SourceWatch, listed breast thermography, women’s hormones, iodine, and thyroid and adrenal conditions among her lecture topics, and described her as president emeritus of the Alliance for Natural Health USA and a columnist for, among others, NaturalNews.com and the Canadian outlet TheAgora.

WhenWhat happened
May 2010In Veryzer v. Secretary of HHS (No. 06-522V), a U.S. vaccine-injury case, Special Master Richard B. Abell excludes her expert report as unreliable. He finds she is “unqualified to opine” on neurology, calls her report “thoroughly unscientific,” and excludes the report of the other expert in the case, Canadian physician Andrew Moulden, on the same grounds. (Order filed 19 May 2010; public version 15 June 2010.)
Jan 2015Her Australian speaking tour collapses as venue after venue cancels. Osteopathy Australia says she is not registered as a health practitioner there. She calls off the tour, citing threats; police could not confirm them.
2017The $623 “Mastering Vaccine Info Boot Camp” begins.
Dec 2020A Facebook page she managed is taken down.
Mar 2021Named in the Center for Countering Digital Hate’s “Disinformation Dozen,” twelve accounts it found responsible for most anti-vaccine content shared on Facebook and Twitter.
Jun 2021Called by Republican legislators as an expert witness before the Ohio House Health Committee, she claims COVID-19 vaccines can magnetize people and “interface” with cell towers.
10 Jul 2021Sells a $165–$199 webinar on how COVID-19 injections “can make you sick… even kill you.”
14 Jul 2021A State Medical Board of Ohio investigator visits her office. She doesn’t respond to his card or a follow-up email.
Jul–Sep 2021Twitter permanently suspends her account in July; YouTube removes hers in September, both for COVID-19 misinformation. She is back on X, as @BusyDrT, after Twitter’s change of ownership.
2021–22About 350 complaints reach the board. Through her lawyer, Thomas Renz, she refuses written interrogatories (Sept 2021), a subpoena to a deposition (Nov 2021) and an investigative office conference (July 2022), each time saying the board had no “lawful basis.”
14 Sep 2022The board cites her for failing to cooperate. In October she hosts Florida Surgeon General Joseph Ladapo on her podcast.
27 Jun 2023Takes part in an online fundraiser for Robert F. Kennedy Jr.’s presidential campaign.
9 Aug 2023The Ohio board suspends her licence indefinitely for failing to cooperate, and fines her $3,000. The suspension is procedural: the board never ruled on the substance of her testimony.
Aug–Nov 2023She appeals to the Franklin County Court of Common Pleas. The court refuses to stay the suspension (15 Sept) and dismisses the appeal for lack of jurisdiction (11 Oct). A second appeal is filed, then voluntarily dropped (21 Nov).
10 Apr 2024The board votes 7–2 to reinstate her, having found she met the conditions of its 2023 order, including the $3,000 fine.
1 Oct 2025Her Ohio licence expires. In July 2026 the board’s register lists it as “Inactive” and “Expired.”
Jun 2024The U.S. Department of Justice sues her for unpaid federal taxes.
Apr 2026U.S. District Judge J. Philip Calabrese orders her to pay $698,982 in back taxes, penalties and interest for 2001, 2012 and 2013. She has said she was targeted for her vaccine views.
12 Nov 2026Vaccine Choice Canada quotes her calling the childhood schedule a “Pediatric Poisoning Schedule.”

4. The Canadian connection

Tenpenny has no Canadian licence and, as far as we can find, no record of a Canadian speaking tour. She doesn’t need one. Her name and material keep crossing the border.

A tick means only what its column says. Appearing on her show is not an endorsement of her views. An empty cell means we found no record. Private individuals are described, not named. Corrections are welcome.

What the record shows, and doesn’t
  1. Her licence was suspended for refusing to cooperate, not for what she said. The Ohio board never ruled on whether her testimony was false. That question was simply never reached.
  2. She was reinstated in April 2024, but her licence has since expired. As of July 2026, the board’s register shows it “Inactive” and “Expired” since 1 October 2025. She is still introduced as “Dr.” and still speaks about vaccines.
  3. The tax judgment is a civil matter, not a criminal one.
  4. What is beyond dispute: COVID-19 vaccines do not magnetize people, the childhood schedule is not “poisoning,” and no mRNA vaccine is given to newborns in Canada.
