Executive summary

Yes. Michael (Mike) Yeadon continued to make public statements about COVID-19 vaccines in 2023, appearing in interviews and online video platforms in which he repeated skeptical and conspiratorial claims about the pandemic and vaccines; one documented example is a February 10, 2023 interview posted on Brighteon where he questioned whether there had “even a real COVID pandemic” and raised doubts about vaccine narratives [1]. Reporting assembled here also shows his 2020–2021 record of public claims about Pfizer and COVID-19 vaccines that were widely debunked, which provides context for assessing his 2023 output [2] [3] [4].

1. Public appearances in 2023 — evidence exists on fringe platforms

Documentation in the provided sources records at least one 2023 appearance in which Yeadon spoke about the pandemic and vaccines: a February 10, 2023 interview posted on Brighteon titled “Fmr. Pfizer VP Dr. Michael Yeadon -- Was There Even a Real COVID Pandemic?” [1], showing he was publicly voicing views that challenge the mainstream account of COVID-19 and vaccine safety into 2023.

2. Substance of the 2023 statements — skeptical and conspiratorial framing

The cited 2023 interview shows Yeadon asking open-ended, skeptical questions about the pandemic’s reality and origins, consistent with the themes he expressed earlier — claims that question vaccine safety, trial adequacy and pandemic narratives — and pointing viewers to other alternative-media materials [1]; other sources document similar lines of argument he advanced in 2020–2021, including assertions about reproductive toxicology and vaccine risks that were fact-checked and disputed by mainstream outlets [4] [5].

3. Track record matters — how mainstream outlets treated his claims

Mainstream fact-checkers and news organizations have repeatedly flagged Yeadon’s earlier statements about COVID-19 and vaccines as false or misleading: AP and Reuters documented and debunked claims he made in 2020–2021 and described how his profile fed anti-vaccine movements [2] [3], while Reuters’ fact-checks pulled apart specific claims he made about asymptomatic infection, variants and risks to pregnant women [4]; that pattern is relevant when evaluating his 2023 pronouncements because the same themes recur [1].

4. Platforms and reach — mostly outside mainstream channels

The 2023 example identified is hosted on alternative or fringe media (Brighteon) rather than established scientific journals or major news outlets [1], which mirrors how many of Yeadon’s vaccine-related claims have circulated: amplified on social media and niche sites with anti-vaccine audiences rather than through peer-reviewed publications or mainstream platforms that would subject claims to scientific vetting [3] [6].

5. Limits of available reporting — what cannot be established from these sources

The assembled reporting does not document a mainstream peer-reviewed paper, regulatory filing, or widely published op-ed by Yeadon in 2023 specifically addressing Pfizer’s COVID‑19 vaccines, nor does it provide a comprehensive catalog of every interview or social media post he may have made that year; therefore while there is clear evidence he publicly commented on vaccines in 2023 on at least one platform [1], these sources do not prove whether he authored formal published works about Pfizer vaccines in mainstream outlets during 2023.

6. Conclusion — direct answer with caveats

Directly: yes — Michael Yeadon published public statements about COVID-19 vaccines in 2023, as demonstrated by recorded interviews such as the February 10, 2023 Brighteon interview where he questioned pandemic narratives and vaccine safety [1]; however, the available sources show those 2023 statements appeared on alternative media and social platforms rather than in peer‑reviewed literature or mainstream outlets, and his broader history of debunked claims (documented by AP, Reuters and other fact-checkers) remains essential context for evaluating his 2023 remarks [2] [3] [4].
