By Michael Nevradakis, Ph.D., Children's Health Defense - During his stay, Marxen, who had not received a COVID-19 vaccine, was administered more than 50 medications, including remdesivir, vancomycin, fentanyl and midazolam, and in the days prior to his death, he was placed on a ventilator... At the time of his death, Marxen had “multiple organ system failure including renal failure, endocarditis, hyperkalemia, MRSA [methicillin-resistant Staphylococcus aureus] pneumonia, MRSA bacteremia and sepsis,” Riggs said.
