Clinical narrative: Was immunocompromised after 1st dose of moderna vaccine/Was not immunocompromised before 1st dose of moderna vaccine; This spontaneous case was reported by a consumer and describes the occurrence of IMMUNODEFICIENCY (Was immunocompromised after 1st dose of moderna vaccine/Was not immunocompromised before 1st dose of moderna vaccine) in a 75-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch nos. 031L20A, 025A21A and 049E21A) for COVID-19 vaccination.     No Medical History information was reported.   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 19-Aug-2021, received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On an unknown date, the patient experienced IMMUNODEFICIENCY (Was immunocompromised after 1st dose of moderna vaccine/Was not immunocompromised before 1st dose of moderna vaccine) (seriousness criterion medically significant). At the time of the report, IMMUNODEFICIENCY (Was immunocompromised after 1st dose of moderna vaccine/Was not immunocompromised before 1st dose of moderna vaccine) outcome was unknown.        The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) was unknown.
