ASKU) for COVID-19 prophylaxis. The occurrence of additional non-serious events is detailed below.     Patient had not received any other vaccines in the 4 weeks prior to COVID-19 vaccine.  Concurrent medical conditions included Blood pressure high (controlled with medications,), Diabetes and High cholesterol. Concomitant products included METFORMIN for Diabetes, ATORVASTATIN for High cholesterol.   On 31-Mar-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 30-Apr-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On 01-Dec-2021, received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. In 2021, the patient experienced CHRONIC INFLAMMATORY DEMYELINATING POLYRADICULONEUROPATHY (They diagnosed him with CIBP like a chronic GBS syndrome) (seriousness criteria hospitalization and medically significant) and GUILLAIN-BARRE SYNDROME (They diagnosed him with CIBP like a chronic GBS syndrome) (seriousness criteria hospitalization and medically significant). On an unknown date, the patient experienced WEIGHT DECREASED (Within 2 Months he lost 75 pounds.) and COVID-19 (tested positive for COVID Disease). At the time of the report, CHRONIC INFLAMMATORY DEMYELINATING POLYRADICULONEUROPATHY (They diagnosed him with CIBP like a chronic GBS syndrome) and GUILLAIN-BARRE SYNDROME (They diagnosed him with CIBP like a chronic GBS syndrome) had not resolved and WEIGHT DECREASED (Within 2 Months he lost 75 pounds.) and COVID-19 (tested positive for COVID Disease) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In April 2021, Blood test: abnormal. In April 2021, Protein total: off the chart.. In April 2021, Red blood cell count: off the chart.. In April 2021, Rheumatoid factor: Rheumatoid numbers were off the chart. In April 2021, White blood cell count: off the chart.. In 2021, Laboratory test: annual physical and lab works 2 months before vaccination, and all lab works were normal.. On an unknown date, SARS-CoV-2 test: Positive.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter considered CHRONIC INFLAMMATORY DEMYELINATING POLYRADICULONEUROPATHY (They diagnosed him with CIBP like a chronic GBS syndrome) and GUILLAIN-BARRE SYNDROME (They diagnosed him with CIBP like a chronic GBS syndrome) to be related. No further causality assessments were provided for WEIGHT DECREASED (Within 2 Months he lost 75 pounds.) and COVID-19 (tested positive for COVID Disease).    The patient had no other vaccines within 4 months of the Moderna vaccination. Prior to vaccination and during vaccination time he was on High Blood Pressure medications.  After the first shot, patient started having Fatigue and Strength loss. and trouble standing up. He had to grab to something and push himself up, to stand up.
