RE: He was not ‘the’ VP of Pfizer, nor did he work in the department that had anything to do with vaccines, etc.
According to Wikipedia:
https://en.m.wikipedia.org/wiki/Michael_Yeadon
Yeadon served as the chief scientist and vice-president of Pfizer’s allergy and respiratory research unit in Sandwich, Kent, where he oversaw the development of drugs for asthma and chronic obstructive pulmonary disease (COPD). During his work at Pfizer, Yeadon was responsible for the selection of targets and the progression of new molecules into human trials. His unit developed inhaled and oral NCEs that showed positive results in clinical trials for asthma, allergic rhinitis and COPD.
Yeadon, left Pfizer in 2011 and with three colleagues founded the biotechnology company Ziarco, which was later sold to Novartis for $325 million in 2017.
Thank you.
