Hand tremors; Chills; Pneumonia; Sore arm; Fever with fluctuation in temperatures; This spontaneous case was reported by a consumer (subsequently medically confirmed) and describes the occurrence of PNEUMONIA (Pneumonia) in a 76-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch nos. 032L20A and 026L20A) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.     No medical history was reported.  Concomitant products included LOSARTAN POTASSIUM, HYDROCHLOROTHIAZIDE, FLUTICASONE PROPIONATE (FLONASE ALLERGY RELIEF), MONTELUKAST SODIUM (SINGULAIR), PYRIDOSTIGMINE BROMIDE (MESTINON), MIRABEGRON, TAMSULOSIN HCL and AMOXICILLIN, CLAVULANIC ACID (AUGMENTIN [AMOXICILLIN;CLAVULANIC ACID]) for an unknown indication.   On 25-Jan-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 22-Feb-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On 23-Feb-2021, the patient experienced PAIN IN EXTREMITY (Sore arm) and PYREXIA (Fever with fluctuation in temperatures). On 04-Mar-2021, the patient experienced PNEUMONIA (Pneumonia) (seriousness criterion medically significant). On an unknown date, the patient experienced TREMOR (Hand tremors) and CHILLS (Chills). At the time of the report, PNEUMONIA (Pneumonia), TREMOR (Hand tremors), PYREXIA (Fever with fluctuation in temperatures) and CHILLS (Chills) had resolved and PAIN IN EXTREMITY (Sore arm) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 23-Feb-2021, Body temperature: 101.7 (Inconclusive) 101.7 degrees F.. On 24-Feb-2021, Body temperature: 101.7 to 103.9 degrees f (Inconclusive) 101.7 to 103.9 degrees F. On 26-Feb-2021, Body temperature: 97.9 to 99.8 degrees f (Inconclusive) 97.9 to 99.8 degrees F. On 27-Feb-2021, Body temperature: 97.5 - 99.6 degrees f (Inconclusive) 97.5 - 99.6 degrees F.. On 28-Feb-2021, Body temperature: 104.4 - 103.8 degrees f (Inconclusive) temperature range was 97.3 - 99.7 degrees F.. In 2021, Chest X-ray: pneumonia (abnormal) Pneumonia was confirmed.         Treatment for the event included paracetamol.  Pneumonia is of an infective origin, hence assessed as not causally associated with mRNA-1273 administration based on the known profile of the product.  However, based on the information provided which includes a temporal association between the use of mRNA-1273 vaccine and onset of the other reported events, a causal relationship cannot be excluded.  Pyrexia and chills are consistent with the product known safety profile.   This case was linked to MOD-2021-031492 (Patient Link).   Most recent FOLLOW-UP information incorporated above includes: On 29-Apr-2021: Medically confirmed changed.
