On 09-May-2021, the patient experienced PALPITATIONS (Irregular heart rate/palpitations/her heart was pounding) and FEELING ABNORMAL (the patient felt really weird when the first shot was injected into her for about 40 minutes). 09-May-2021, the patient experienced BLOOD PRESSURE DECREASED (Drop in blood Pressure). In May 2021, the patient experienced VACCINATION SITE PAIN (the patient felt some pain around the injection site). On 02-Jun-2021, the patient experienced DYSPNOEA (Difficulty breathing), CHEST DISCOMFORT (Chest tightness), FEELING HOT (Feeling hot), FLUSHING (Flushing) and PARAESTHESIA (Prickling/Tingling). On 03-Jun-2021, the patient experienced APPENDICITIS (Appendicitis) (seriousness criteria hospitalization and medically significant). In June 2021, the patient experienced PRESYNCOPE (almost passed out) and TINNITUS (ears were ringing). On an unknown date, the patient experienced DIZZINESS (felt faint) and HEADACHE (bit of a headache). The patient was hospitalized on sometime in June 2021 due to APPENDICITIS. The patient was treated with Surgery (Apendicectomy) for Appendicitis. On 09-May-2021, BLOOD PRESSURE DECREASED (Drop in blood Pressure) had resolved. On 04-Jun-2021, APPENDICITIS (Appendicitis), PALPITATIONS (Irregular heart rate/palpitations/her heart was pounding), DYSPNOEA (Difficulty breathing), CHEST DISCOMFORT (Chest tightness), FEELING HOT (Feeling hot) and FLUSHING (Flushing) had resolved, PARAESTHESIA (Prickling/Tingling) outcome was unknown. At the time of the report, PRESYNCOPE (almost passed out), FEELING ABNORMAL (the patient felt really weird when the first shot was injected into her for about 40 minutes), DIZZINESS (felt faint), TINNITUS (ears were ringing) and HEADACHE (bit of a headache) outcome was unknown and VACCINATION SITE PAIN (the patient felt some pain around the injection site) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 09-May-2021, Blood pressure measurement: drop (Low) Drop in Blood Pressure. On an unknown date, Blood pressure measurement: little low (Low) little low.     mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosing remained unchanged.   For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter considered APPENDICITIS (Appendicitis) and BLOOD PRESSURE DECREASED (Drop in blood Pressure) to be possibly related. No further causality assessments were provided for PRESYNCOPE (almost passed out), PALPITATIONS (Irregular heart rate/palpitations/her heart was pounding), DYSPNOEA (Difficulty breathing), CHEST DISCOMFORT (Chest tightness), FEELING HOT (Feeling hot), FLUSHING (Flushing), PARAESTHESIA (Prickling/Tingling), FEELING ABNORMAL (the patient felt really weird when the first shot was injected into her for about 40 minutes), DIZZINESS (felt faint), TINNITUS (ears were ringing), VACCINATION SITE PAIN (the patient felt some pain around the injection site) and HEADACHE (bit of a headache).    Treatment information was not provided. The patient's body felt like it was going into red alert mode; like it did not like what was in the shot.  She felt faint, so the pharmacist took her blood pressure (which was usually on the higher side, because of her weight) and it was super low. Again after 15 minutes, bp was checked. It was a little low, but it was okay for her to go home. She felt some pain around the injection site for the next few days and had a bit of a headache, but that was it. When the patient was taking a shower on 02-Jun-2021, her right lower abdomen started hurting bad. Then that night when she got up to use the bathroom, it hurt so bad that her ears were ringing, and she almost passed out. The morning of 03-Jun-2021, her husband took her to the emergency room, and she was informed that she had appendicitis and it was needed to perform emergency surgery to remove it.
