Spike Protein and blood transfusions
+7 No, the spike protein from COVID-19 vaccines does not get passed to another person through a blood transfusion in any meaningful or harmful way. The mRNA in the vaccine is temporary, and vaccine components do not linger in the bloodstream or transfer via blood transfusion. College of American Pathologists +4 - Vaccine Mechanism: The vaccine instructs cells to produce a small amount of spike protein for a very limited time; it does not remain in the blood. - Safety Confirmed: Experts and organizations, including the Red Cross, confirm that blood from vaccinated donors is safe and does not cause adverse outcomes for recipients. - No Long-Term Presence: The spike protein produced is rapidly broken down and does not circulate long enough to be present in blood donations. - Antibodies Only: While antibodies created by the vaccine (not the spike protein itself) can be transferred through plasma, these are harmless and sometimes beneficial to the recipient. There is no evidence that vaccinated blood poses a risk to patients.
