A series of online posts went viral recently after showing that a five‑month‑old baby died within 24 hours of breastfeeding from a mother vaccinated with Pfizer’s mRNA vaccine. The infants cause of death was thrombotic thrombocytopenic purpura (TTP)—a rare and extreme clotting disorder. This claim comes from the Vaccine Adverse Event report, and several independent media outlets summarized the same case in detail. For instance, TechStartups reported recently that the VAERS data show: “The baby developed a rash the day after the mother’s second Pfizer dose… within 24 hours was inconsolable, developed fever… hospitalized… continued to decline and passed away. Diagnosis of TTP.” The VAERS report itself confirms a tight timeline: The mother was given a Pfizer dose on March 17, and her infant became ill on March 18 and died shortly thereafter. The clinician reporter questioned whether the transfer of spike protein through breast milk might have triggered inflammation and clotting.
