Pharmacovigilance comment: the serious events of cellulitis and inflammation at implant site, and the non-serious events of pain, swelling, erythema, warmth, bruising, induration at implant site and discomfort at injection site were considered expected and possibly related to the treatment.Serious criteria include the need for multiple medical interventions to prevent permanent damage.Potential root causes are the treatment procedure and injection procedure associated with inadequate aseptic technique.Potential contributory factor include pfizer covid-19 vaccine.The non-serious events of feeling abnormal and tenderness were considered unexpected, unrelated to the treatment.No treatment was performed to affected area.Alternative etiology include undiagnosed medical conditions.The case meets the criteria for expedited reporting to the regulatory authorities.Engineering evaluation: no corrective or preventive actions are deemed necessary based on the outcome of the performed investigations.Manufacturer narrative: routine investigations have been performed and provide sufficient information to assess the potential root cause and indicate a possible association to the treatment procedure.The reported lot number was valid and verified the reported product.The information in this case does not indicate a nonconforming product or malfunction.The performed investigations are therefore considered adequate and no additional investigations will be conducted.
