Additional information was received on 03Apr2024 from granddaughter of the patient: Event blindness transient verbatim was updated. loading dose was added. Therapy start date was added. Clinical course was added. Narrative was updated. Additional information was received on 10Apr2025 from patient's daughter: event death, concomitant medications, strength were added and text amended accordingly. Additional information was received on 15Apr2025 from Medical assistant. New event of pemphigoid was added. Concomitant medication was added. Text amended accordingly. Additional information was received on 15Apr2025 from physician. new event Blister, Rash pruritic, Rash, Skin lesion, condition aggravated, Red blood cell count decreased, Haemoglobin decreased, Hematocrit decreased and Blood pressure inadequately controlled was added. Concomitants, medical history, treatment drugs were added. Event of blindness transient was deleted. Text amended.  COMIRNATY (2024-2025 FORMULA) is under agreement with BIONTECH SE.; Sender's Comments: The limited information in this report precludes a full assessment of the case. However, per company guidance, "death cause unknown" is processed as "related" until sufficient information becomes available to confirm an unrelated cause of death. Case will be reassessed when follow-up information such medical history, concomitant medications and event term details especially death cause and autopsy results is received. There is no reasonable possibility that the events pemphigoid, skin ulcer, blister, skin lesions aggravated were related to Comirnaty (2024-2025 Formula). These are more likely associated with the history of squamous cell carcinoma. There is no reasonable possibility that the events peripheral swelling, red blood cell decreased, hemoglobin decreased, and hematocrit decreased were related to Comirnaty (2024-2025 Formula). These are more likely intercurrent conditions. The events blood pressure inadequately controlled is more likely associated with the history of atrial fibrillation. There is a reasonable possibility that the event rash is related to Comirnaty (2024-2025) based on known drug safety profile.
