suprisely even snopes says Michael Yeadon stated it, even though they try to discredit him over job title with no proof backing it up. https://www.snopes.com/fact-check/michael-yeadon-vaccine-death/

"Until 2011, Michael Yeadon worked as the vice president and chief scientist in a drug discovery research unit at Pfizer. The division he headed focused on allergy and respiratory medical research — not vaccines or infectious disease. At the time of the unit's closure, research focused on developing compounds that targeted asthma and chronic obstructive pulmonary disease. Yeadon's title was not "Vice President and Chief Science Officer of Pfizer" as a video that went viral in April 2021 claimed, and many of the claims he made were unfounded and lacked scientific or empirical evidence."

Ironic how they call him out for lack of scientific or empirical evidence when that is exactly what they have with the vaccines. Humans are the test subjects.
