The occurrence of additional non-serious events is detailed below.     The patient's past medical history included Stenosis.   On 03-Feb-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 03-Mar-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On 27-Oct-2021, received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On 28-Oct-2021, the patient experienced OROPHARYNGEAL PAIN (sore throat) and MYALGIA (extremely sore/minor soreness). On 29-Oct-2021, the patient experienced FEELING COLD (feeling like a cold) and DIARRHOEA (extreme diarrhea). On 30-Oct-2021, the patient experienced RHINORRHOEA (runny nose) and PYREXIA (fever). On 31-Oct-2021, the patient experienced LIVER FUNCTION TEST ABNORMAL (liver test showed low reading) and WHITE BLOOD CELL COUNT DECREASED (lymphocytes were real low, like a sign of infection). On an unknown date, the patient experienced PRODUCTIVE COUGH (spitting up phlegm) and MONOCLONAL IMMUNOGLOBULIN PRESENT (high Spike abx result of 728). The patient was treated with LOPERAMIDE HYDROCHLORIDE (IMODIUM) for Adverse event, at an unspecified dose and frequency; AZITHROMYCIN (Z-PAK) for Adverse event, at an unspecified dose and frequency; METHYLPREDNISOLONE for Adverse event, at a dose of 4 mg(6 tabs on 1st day, 5 tabs on 2nd day, 4 tabs on 3rd day); GUAIFENESIN, PSEUDOEPHEDRINE HYDROCHLORIDE (MUCINEX D) for Adverse event, at an unspecified dose and frequency and AMMONIUM CHLORIDE, GLYCYRRHIZA GLABRA LIQUID EXTRACT (EXPECTORANT [AMMONIUM CHLORIDE;GLYCYRRHIZA GLABRA LIQUID EXTRACT]) for Adverse event, at an unspecified dose and frequency. On 29-Oct-2021, OROPHARYNGEAL PAIN (sore throat) had resolved. At the time of the report, FEELING COLD (feeling like a cold) and DIARRHOEA (extreme diarrhea) had resolved and RHINORRHOEA (runny nose), LIVER FUNCTION TEST ABNORMAL (liver test showed low reading), WHITE BLOOD CELL COUNT DECREASED (lymphocytes were real low, like a sign of infection), PRODUCTIVE COUGH (spitting up phlegm), MONOCLONAL IMMUNOGLOBULIN PRESENT (high Spike abx result of 728), PYREXIA (fever) and MYALGIA (extremely sore/minor soreness) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 31-Oct-2021, Liver function test: low reading low reading. On 31-Oct-2021, Lymphocyte count: low low. On an unknown date, SARS-CoV-2 antibody test: high HIGH.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter did not provide any causality assessments.   The day after the shot, it was extremely sore, which passed the next day. 2 days after the shot, started feeling like a cold and had extreme diarrhea for 4 hours, which was stopped with Immodium. The next day, experienced sore throat, runny nose, which progressed to fever. No concomitant medication provided. It was reported that patient received complete blood work and liver test, there was no signs of covid 19 and patients liver showed low reading and lymphocytes were real low, like a sign of infection. But he had no viral or bacterial infection when tested. The patient liver test was stable spitting up phlegm and having runny nose. The patient took strong nasal decongestant (Muconex D) and an expectorant felt a little better than the earlier week but still having phlegm and runny nose.
