Gastroparesis; STRUGGLING TO KEEP WAIT ON; This spontaneous case was reported by a consumer and describes the occurrence of IMPAIRED GASTRIC EMPTYING (Gastroparesis) in an adult female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.    Co-suspect product included non-company product UPADACITINIB (RINVOQ) for Rheumatoid arthritis.    Concomitant products included mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination.   On an unknown date, the patient received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form and UPADACITINIB (RINVOQ) (Oral) at an unspecified dose. On an unknown date, the patient experienced IMPAIRED GASTRIC EMPTYING (Gastroparesis) (seriousness criterion medically significant) and UNEVALUABLE EVENT (STRUGGLING TO KEEP WAIT ON). At the time of the report, IMPAIRED GASTRIC EMPTYING (Gastroparesis) and UNEVALUABLE EVENT (STRUGGLING TO KEEP WAIT ON) had not resolved.        The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) was unknown.

Physician advised to wait on booster for covid  vaccine. Patient had steroid shots in knee. It was unknown if patient was enrolled in a covid-19 vaccine trial. Treatment medications were not reported.  The reporter's causality for the event(s) of gastroparesis and struggling to keep wait on with rinvoq(upadacitinib) was a reasonable possibility.
