Oh, just a mistake huh? Ya mean after Pfizer made it's $Billions and thousands of people died and were injured as a result? No, they were part of a criminal conspiracy to allow an untested gene therapy to be distributed to the public writ large in violation of the Geneva Convention prohibiting drug testing on people without their knowledge or consent. Further they conspired with media and Big Pharma to ban the use of Ivermectin and Hydroxychloroquine which were cheap and widely available to stop Covid from getting bad enough that it required hospitalization. Then the hospitals and clinics became part of the conspiracy to give toxic expensive Remdesivir to patients too weak to resist that shut down their kidneys or destroyed their lungs with ventilators thus allowing each death to give these same institutions a windfall of taxpayer money from the federal government.

Sorry, the "mistake defense" doesn't fly Mr. FDA attorney. Premeditated murder and conspiracy to commit murder are the charges.
