The patient experienced lack of drug effect, drug effect decreased, itching, diarrhea on an unspecified date; diarrhea recurrent and abdominal pain on 26Feb2021; imbalance hormonal/hormonal imbalance, breast lump, shoulder lump and mass on Jun2021. The action taken in response to the events for adalimumab was dose not changed. The patient had not recovered from drug effect decreased, imbalance hormonal, breast lump and shoulder lump; recovering from itching; recovered from diarrhea on an unspecified date, recovered from diarrhea recurrent and abdominal pain on Mar2021. Outcome of lack of drug effect was unknown.   Causality between the events and BNT162b2 was reported as: not related for itching, diarrhea, breast lump and mass. Probable for abdominal pain and imbalance hormonal. Probable and not assessable for diarrhea recurrent. Not reported for drug effect decreased and lack of drug effect. Causality between the events and Humira was reported as: not assessable for itching, diarrhea, imbalance hormonal, breast lump, and mass. Not related with abdominal pain. Not related and not assessable for diarrhea recurrent. Not reported for drug effect decreased and lack of drug effect.  The lot number for the vaccine, BNT162b2, was not provided and will be requested during follow up.; Sender's Comments: A causal association between BNT162B2 and the reported events drug effect decreased, lack of drug effect, abdominal pain, imbalance hormonal, and diarrhea recurrent cannot be excluded based on a compatible temporal relation. The rest of the events are likely due to underlying medical conditions or are intercurrent and are unrelated to suspect product BNT162B2. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events.
