Family history included Prostate cancer (Her husband's cancer was pre-existing to any COVID vaccines, for a while ago and undergoing radiation before COVID-19, in 2019 or something like that.) since an unknown date. Concurrent medical conditions included COPD (she was having a little COPD from growing up in a smoking house, but she never smoked) and Clinical trial participant (She was enrolled in a clinical trial and had participated in trials in the past.

On 17-Dec-2025, the patient received sixth dose of mRNA-1283 (MNEXSPIKE PFS) (Intramuscular use) 1 dosage form. On an unknown date, the patient started Pre-filled Syringe (unknown route) at an unspecified dose. On an unknown date, the patient experienced PAIN IN EXTREMITY (arm hurt a little bit), FEELING ABNORMAL (felt a little bit different for a day or so) and FATIGUE (tired). At the time of the report, PAIN IN EXTREMITY (arm hurt a little bit), FEELING ABNORMAL (felt a little bit different for a day or so) and FATIGUE (tired) had resolved. DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Continuous glucose monitoring: 5.8 and 5.3. On an unknown date, Glycosylated haemoglobin: pre-diabetic. The patient had no vaccines within the past 4 weeks of any vaccine. She helped out in trials because she was in pretty good shape. After the vaccine, the patient and her husband were taking their ninety-minute walk. The patient wore a Continuous Glucose Monitoring device and monitored everything she ate so she was no longer pre-diabetic. She got a Continuous Glucose Monitoring and brought her levels down. It did not really bother her; she could still do 5 flights of stairs in 45 seconds. She did not do this on the day when she got the vaccine. No concomitant medication was reported. The patient and her husband always got Moderna vaccines. They tried and got the vaccine every 34 months. They did not have COVID. Her doctor told her, if she was not having any side effects, it meant the vaccine was not working well because there should be side effects for the immune system to fight back. It was unknown if the patient experienced any additional symptoms/events. No treatment medication was reported. This case was linked to MOD-2026-794792, MOD-2026-794793 (Patient Link).
