Symptom narrative

unsure if his low immune system was pre-existing since they just started checking it a year ago; This spontaneous case was reported by a consumer and describes the occurrence of IMMUNODEFICIENCY (unsure if his low immune system was pre-existing since they just started checking it a year ago) in an 89-year-old male patient who received mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (batch no. 3043156) for COVID-19 prophylaxis. Concurrent medical conditions included Breathing difficult and Chronic leukemia (x20 years). On 23-Sep-2024, the patient received ninth dose of mRNA-1273.712 (SPIKEVAX 2024-2025 PFS) (Intramuscular use) .5 milliliter. On an unknown date, the patient experienced IMMUNODEFICIENCY (unsure if his low immune system was pre-existing since they just started checking it a year ago) (seriousness criterion medically significant). At the time of the report, IMMUNODEFICIENCY (unsure if his low immune system was pre-existing since they just started checking it a year ago) outcome was unknown. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, White blood cell count: white count being so high (over 100,000) for 20 years. No concomitant medication was reported. The patient received every Moderna vaccine that had come out since it was all started and the last one, he had was September 2024. Patient previously received Moderna vaccines on 01-Jan-2021 (lot#025L20A), 13-Jan-2021 (lot#025L20A), 10-Feb-2021 (lot#024M20A), 27-Sep-2021 (lot#041B21A), 07-Feb-2022 (lot#007J21-2A), 09-Sep-2022 (AS7140C), 20-Apr-2023 (lot#065H22A) and 02-Oct-2023 (lot#203F23A-1).

The patient needed infusions to bring his hemoglobin and IgG back up every 3 months. The patient's most of the problems were on account of his chronic leukemia and his white count being so high (over 100,000) for 20 years. The patient was never had any ill effects from any of his vaccines.
