In 2014, the patient started ADALIMUMAB (HUMIRA) (Subcutaneous) Citrate free. In 2017, ADALIMUMAB (HUMIRA) (Subcutaneous) dosage was changed to Citrate free. On 03-Jul-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 28-Jul-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On 03-Jul-2021, the patient experienced VACCINATION SITE BRUISING (Took covid-19 vaccine had bruised arm), VACCINATION SITE NODULE (Knot at injection site) and ABDOMINAL PAIN (Abdominal pain). In July 2021, the patient experienced INTESTINAL OBSTRUCTION (Ate corn and peas at the same time and caused a blockage in intestine) (seriousness criterion medically significant). On 28-Jul-2021, the patient experienced VACCINATION SITE NODULE (recurred knot at injection site), VACCINATION SITE BRUISING (took second Covid-19 vaccine recurred bruising on the arm) and ABDOMINAL PAIN (recurred abdominal pain). On an unknown date, the patient experienced CROHN'S DISEASE (Crohn's disease aggravated / Crohn's disease flare up) (seriousness criterion medically significant) and WEIGHT INCREASED (Weight gain / gained 50 pounds). The patient was treated with HYDROMORPHONE HYDROCHLORIDE (DILAUDID) at an unspecified dose and frequency. In July 2021, INTESTINAL OBSTRUCTION (Ate corn and peas at the same time and caused a blockage in intestine), VACCINATION SITE BRUISING (Took covid-19 vaccine had bruised arm), VACCINATION SITE NODULE (Knot at injection site), VACCINATION SITE NODULE (recurred knot at injection site), VACCINATION SITE BRUISING (took second Covid-19 vaccine recurred bruising on the arm), ABDOMINAL PAIN (Abdominal pain) and ABDOMINAL PAIN (recurred abdominal pain) had resolved. At the time of the report, CROHN'S DISEASE (Crohn's disease aggravated / Crohn's disease flare up) and WEIGHT INCREASED (Weight gain / gained 50 pounds) had not resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Weight: Gain 50 Pounds.         It was unknown if patient was enrolled in a COVID-19 Vaccine Trial.   This case was identified as part of a retrospective clean-up activity where certain emails received in the Moderna mailbox were missed to be booked-in.  Company comment:  This spontaneous case concerns a 52-year-old female patient with relevant medical history of Crohn's disease, who experienced the unexpected, serious  (medically significant ) events of Crohn's disease (Crohn's disease aggravated / Crohn's disease flare up), and Intestinal obstruction on unknown dates in the context of receiving a dose of mRNA-1273 vaccine.  Onset latency cannot be determined as date of onset of events were not provided. The event intestinal obstruction occurred during  the same month of vaccination of both doses as the two doses were given within the same month. Patient received a 2-dose primary series of mRNA-1273 vaccine given 25 days apart. The relevant medical history of Crohn's disease  remains a confounder as the disease itself is known to result in flares, and with intestinal obstruction as the most common complication.  The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report   Most recent FOLLOW-UP information incorporated above includes: On 17-Aug-2021: Follow-up received include medical history added, Drug allergy added, Concomitant added, Event Abdominal pain, Vaccination site nodule added.; Sender's Comments: This spontaneous case concerns a 52-year-old female patient with relevant medical history of Crohn's disease, who experienced the unexpected, serious  (medically significant ) events of Crohn's disease (Crohn's disease aggravated / Crohn's disease flare up), and Intestinal obstruction on unknown dates in the context of receiving a dose of mRNA-1273 vaccine.
