Dr. Peter McCullough’s X Post (March 25, 2025) Academic Medical Centers have Not Updated Doctors and Patients on the Long-Lasting Spike Protein ( X post ) MedRxiv Preprint (February 18, 2025) Title: Immunological and Antigenic Signatures Associated with Chronic Illnesses after COVID-19 Vaccination ( MedRxiv ) Key Points (Based on Web Result Summaries): This is the primary source of the Yale study, led by Akiko Iwasaki and colleagues. It confirms that some PVS participants had detectable SARS-CoV-2 spike protein in their bloodstream, with persistence up to 709 days post-vaccination.
