Pneumonia; Coughing; Low drug level; This is a solicited report received from contactable reporter(s) (Consumer or other non HCP). The reporter is the patient. Other Case identifier(s): 22K-163-4519878-00 (Agency).  A 61-year-old female patient received BNT162b2 (BNT162B2), as dose number unknown, single (Batch/Lot number: unknown) intramuscular for covid-19 immunisation; adalimumab (HUMIRA), first regimen (Lot number: 1164842) at unk (cf) and second regimen (ongoing) (Lot number: 1164842) at weekly (unk, weekly (1 in 7 d)), all subcutaneous for crohn's disease.

The following information was reported: PNEUMONIA (hospitalization, medically significant), outcome "recovered"; COUGH (hospitalization), outcome "not recovered", described as "Coughing"; DRUG LEVEL DECREASED (non-serious), outcome "unknown", described as "Low drug level". The action taken for adalimumab was dosage not changed.  Clinical information: On unknown dates, the patient experienced pneumonia, Humira not stayed in patient system so upped it to once a week and coughing with Humira. On an unknown date, pneumonia resolved. The patient stated that Humira was not staying in her system so her physician upped it to once a week.

The reporter's causality for the event(s) of Humira not stayed in patient system so upped it to once a week with Humira (Adalimumab) was a reasonable possibility. The reporter's causality for the event(s) of coughing with Humira (Adalimumab) was no reasonable possibility.  Causality of Humira: Causality for Pneumonia as per reporter (Drug/Vaccine): Not reported and Causality as per Mfr. (Drug/vaccine): Reasonable possibility. Action(s) taken with drug: Dose not changed Dechallenge: N/A. Causality for Low drug level (Drug level decreased). Action(s) taken with drug: Dose increased.
