The occurrence of additional non-serious events is detailed below.     Concurrent medical conditions included Inflammatory arthritis, Egg allergy and Dairy intolerance.   On 20-Dec-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 17-Jan-2022, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On 17-Jan-2022, the patient experienced MATERNAL EXPOSURE DURING BREAST FEEDING (Nursing mother received the vaccine/ She is not sure if her inflammation is affecting her baby). On an unknown date, the patient experienced HAEMATOCHEZIA (Blood in her stool / Little tiny blood clot comes out of stool) (seriousness criterion medically significant), HEPATIC PAIN (liver started hurting), ABDOMINAL PAIN UPPER (gut(stomach) pain/ stomach pain worsened), ABDOMINAL LYMPHADENOPATHY (mesentery are swollen and she has inflammation there), SPLENOMEGALY (Enlarged a spleen), PALPITATIONS (Heart palpitation), CHEST PAIN (Chest pain), DIARRHOEA (started having loose bowel/ Loose bowel worsened), LYMPHADENITIS (Lymph nodes are swollen and she has inflammation there), ELECTROCARDIOGRAM ABNORMAL (abnormal T wave on ECG) and INFLAMMATION (inflammation). On 17-Jan-2022, MATERNAL EXPOSURE DURING BREAST FEEDING (Nursing mother received the vaccine/ She is not sure if her inflammation is affecting her baby) had resolved. At the time of the report, HAEMATOCHEZIA (Blood in her stool / Little tiny blood clot comes out of stool), HEPATIC PAIN (liver started hurting), ABDOMINAL PAIN UPPER (gut(stomach) pain/ stomach pain worsened), ABDOMINAL LYMPHADENOPATHY (mesentery are swollen and she has inflammation there), SPLENOMEGALY (Enlarged a spleen), PALPITATIONS (Heart palpitation), CHEST PAIN (Chest pain), DIARRHOEA (started having loose bowel/ Loose bowel worsened) and LYMPHADENITIS (Lymph nodes are swollen and she has inflammation there) had not resolved and ELECTROCARDIOGRAM ABNORMAL (abnormal T wave on ECG) and INFLAMMATION (inflammation) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 19-Sep-2019, SARS-CoV-2 test: yes (Positive) Covid-19 positive test Yes. In 2022, Computerised tomogram: abnormal (abnormal) Lymph nodes were swollen, mesentery were swollen, and had inflammation there.. In 2022, Electrocardiogram: abnormal (abnormal) Abnormal T wave on ECG. In 2022, Hepatic enzyme: slightly elevated (High) slightly elevated but not concerning.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter did not provide any causality assessments.   Patient had a history relating to mentioned AE and both Acute and Chronic illnesses at the time of vaccination. No concomitant medications were reported. It was reported that the patient had side effects but did not have medical proof or name for them. Two weeks after both doses, she had blood in her stool and a little tiny blood clot came out but there had not been any finding in accordance with that.
