Executive summary
Michael (Mike) Yeadon has repeatedly published and promoted statements opposing COVID-19 vaccines and has co-filed at least one regulatory petition; those statements exist on his own platforms and in activist repostings rather than as any official communication from Pfizer [1] [2] [3]. Yeadon is a former Pfizer vice‑president who left the company in 2011 and has since used independent channels to air vaccine safety claims, many of which have been flagged as false or misleading by independent fact‑checkers [4] [5].
1. Background: who Mike Yeadon is and what he once did at Pfizer
Michael Yeadon worked at Pfizer until 2011 and held senior roles in allergy and respiratory research — a career fact recorded in biographical summaries and industry profiles — but he left Pfizer well before the COVID‑19 pandemic and vaccine programs that followed [4].
2. Did Yeadon “release a Pfizer statement”? — the simplest answer
No authoritative source shows that Yeadon issued any statement on behalf of or as an employee of Pfizer; the public documents and posts attributed to him are self‑published (his Substack and other reposts) or filed jointly with external actors such as Dr. Wolfgang Wodarg as an EMA petition, not as an official Pfizer communication [1] [2] [3].
3. What Yeadon has published and filed: petitions, Substack posts, videos
Yeadon has published long-form statements and technical critiques of mRNA vaccines on his own channels, including a 2024 Substack titled “Statement by Mike Yeadon,” and he was co‑signatory to a December 2020 petition with Wolfgang Wodarg to the European Medicines Agency raising safety concerns about SARS‑CoV‑2 vaccine trials — materials that circulated widely through activist sites and alternative media [1] [2] [3].
4. Media amplification, misattribution, and conspiratorial reposting
Many fringe and partisan outlets republished Yeadon’s claims and sometimes framed them as coming from a current “Pfizer chief scientist,” a misattribution that conflates his prior employment with present authority and has contributed to confusion; multiple sites reproduced his warnings or hosted interviews and videos, amplifying them beyond his self‑published posts [6] [7] [8].
5. Independent vetting: fact‑checks and scientific rebuttals
Independent fact‑checkers and reputable outlets have examined Yeadon’s claims and found several to be false or misleading — for example, assertions about variants and vaccine efficacy and regulatory behavior have been debunked in fact‑checks that conclude his public pronouncements do not align with the scientific consensus and regulatory records [5]. These fact‑checks do not dispute that Yeadon made the statements; they dispute the accuracy of many of his technical and policy claims [5].
6. Motives, amplification, and limitations of available reporting
Yeadon’s messaging has been embraced by anti‑vaccine and conspiracy networks, which have incentives to amplify dissenting former‑industry voices, and many reposting sites carry clear advocacy agendas that shape framing and distribution [7] [8]; available sources document his self‑published statements and petitions but do not provide any evidence he spoke for Pfizer or that the cryptic token “8856cf Verified nut” corresponds to any verifiable document or official release, a limitation that cannot be resolved from the provided reporting [1] [2] [3].
