Here's a link to a very interesting paper entitled: "A Prothrombotic Thrombocytopenic Disorder Resembling Heparin-Induced Thrombocytopenia Following Coronavirus-19 Vaccination" relating to the Oxford/AstraZeneca vaccine -
https://www.researchsquare.com/article/rs-362354/v2
It states: "The study has been funded by the Deutsche Forschungsgemeinschaft (DFG,
German Research Foundation)" and in the section "Conflicts of Interest" it states: "Dr. Eichinger reports personal fees from Bayer, Bristol Myers Squibb, Daichii Sankyo, and
PFIZER, all of which are outside of the submitted work."
As yet, I can find no comparable research on the Pfizer vaccine. This looks very suspicious to me.
