The occurrence of additional non-serious events is detailed below.     No Medical History information was reported.   On 05-Jan-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 05-Feb-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. In February 2021, the patient experienced INTESTINAL OBSTRUCTION (had swollen left mesentery lymph nodes which caused blockage in intestine) (seriousness criteria hospitalization prolonged, medically significant and life threatening), ABDOMINAL DISTENSION (abdominal swelling dissension) (seriousness criteria hospitalization prolonged, medically significant and life threatening), ABDOMINAL LYMPHADENOPATHY (had swollen left mesentery lymph nodes which caused blockage in intestine) (seriousness criteria hospitalization prolonged and medically significant), INFLAMMATION (inflammatory response which resulted in abdominal surgery) (seriousness criteria hospitalization prolonged and medically significant), VOMITING PROJECTILE (started throwing up and had projectile vomiting) (seriousness criteria hospitalization prolonged and medically significant), DIARRHOEA (diarrhea) (seriousness criteria hospitalization prolonged and medically significant), GAIT DISTURBANCE (couldn't go to the bathroom because of intestinal blockage) (seriousness criteria hospitalization prolonged and medically significant) and ABDOMINAL PAIN (intermittent pain in belly). The patient was hospitalized for 14 days due to ABDOMINAL DISTENSION, ABDOMINAL LYMPHADENOPATHY, DIARRHOEA, GAIT DISTURBANCE, INFLAMMATION, INTESTINAL OBSTRUCTION and VOMITING PROJECTILE. The patient was treated with POLYCARBOPHIL CALCIUM (FIBER) ongoing since an unknown date for Pain abdominal, at a dose of UNK, qd; PARACETAMOL (TYLENOL [PARACETAMOL]) for Belly ache, at an unspecified dose and frequency; Surgery (Abdominal Surgery) for Abdominal distension and Surgery (Abdominal Surgery) for Inflammation. At the time of the report, INTESTINAL OBSTRUCTION (had swollen left mesentery lymph nodes which caused blockage in intestine), ABDOMINAL DISTENSION (abdominal swelling dissension), ABDOMINAL LYMPHADENOPATHY (had swollen left mesentery lymph nodes which caused blockage in intestine), INFLAMMATION (inflammatory response which resulted in abdominal surgery), VOMITING PROJECTILE (started throwing up and had projectile vomiting), DIARRHOEA (diarrhea), GAIT DISTURBANCE (couldn't go to the bathroom because of intestinal blockage) and ABDOMINAL PAIN (intermittent pain in belly) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Computerised tomogram: abnormal (abnormal) abdominal swelling dissension.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter considered INFLAMMATION (inflammatory response which resulted in abdominal surgery) to be related. No further causality assessments were provided for INTESTINAL OBSTRUCTION (had swollen left mesentery lymph nodes which caused blockage in intestine), ABDOMINAL DISTENSION (abdominal swelling dissension), ABDOMINAL LYMPHADENOPATHY (had swollen left mesentery lymph nodes which caused blockage in intestine), VOMITING PROJECTILE (started throwing up and had projectile vomiting), DIARRHOEA (diarrhea), GAIT DISTURBANCE (couldn't go to the bathroom because of intestinal blockage) and ABDOMINAL PAIN (intermittent pain in belly).    Concomitant medication was not provided. Patient did not have any Past Medical History and did not took any medication prior to vaccination.   This case was linked to MOD-2022-465089 (Patient Link).

The start dates of the events were not provided. The events intestinal obstruction and abdominal distension were assessed as life-threatening. All events were assessed as medically significant and resulted in hospitalization, except for the event abdominal pain. The report stated that 4 days after vaccination, the patient experienced an inflammatory response which resulted in abdominal surgery.

He also had diarrhea and could not go to the bathroom because of the 'intestinal blockage'. The patient sought consult at the hospital. CT scan showed 'abdominal swelling dissension' and an abdominal surgery was performed. The reporter stated that the doctors mentioned that the cause of the inflammatory response was secondary to the vaccine. No other medication utilized in the hospital for treatment was reported. The patient was hospitalized for almost 2 weeks and was out of work for 3 months. He is now taking fiber daily and unspecified pain medication for the intermittent abdominal pain.
