Due to significant safety concerns, a former vice president and chief scientist for pharmaceutical giant Pfizer, has joined a prominent German physician and past head of a local public health department in petitioning for the immediate suspension of all COVID-19 vaccine studies in Europe.

Dr. Michael Yeadon, who held Pfizer’s most senior research position in the field of allergy and respiratory medicines prior to his departure in 2011, and epidemiologist and pulmonary specialist Dr. Wolfgang Wodarg have filed their petition with the European Medicines Agency (EMA), which is responsible for approving drugs in the European Union at large.
