The most recent information was received on 24-May-2021 and was forwarded to Moderna on an unknown date.    This spontaneous case was reported by a patient and describes the occurrence of COVID-19 (Caught Covid after taking Both Moderna Vaccine/positive covid test), COUGH (coughing), PRODUCTIVE COUGH (phlegm) and DRUG INEFFECTIVE (lack of drug effect) in a 65-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch nos. 0421 and 029A21A) for COVID-19 vaccination.     Concomitant products included MYCOPHENOLATE MOFETIL HYDROCHLORIDE (CELLCEPT [MYCOPHENOLATE MOFETIL HYDROCHLORIDE]) for Immunosuppressant drug therapy, LOSARTAN POTASSIUM (COZAAR), WARFARIN and FLECAINIDE for an unknown indication.   On 04-Feb-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 04-Apr-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On 17-May-2021, the patient experienced COUGH (coughing).
