Investigation: The scope of this investigation included the reported finished goods lot EL9266, fill lot EL9257, and the bulk formulated drug product EL9248. Acceptable review of related documentation, including manufacturing batch records and review of release test results at the time of lot release confirmed that there were no issues which may have resulted in a complaint of this nature. Vendor Investigation?: No. Action Title / Short Descript.: N/A. Design Related?: Document Review Summary:  DEVIATIONS: Complete - Acceptable There were no planned or unplanned deviations recorded during the manufacturing of the reported lot or associated batches that may have caused a complaint of this nature. MANUFACTURING BATCH RECORDS: Complete -Acceptable. The bulk manufacturing batch records for the complaint batch were reviewed as part of this investigation and were found to be acceptable. All processing steps were performed within pre-established parameters. The review of the manufacturing record confirmed that all in process checks, all line startup and end of batch challenges, and all line clearance and cleaning activities were completed satisfactorily. All raw materials used in the complaint batch were of the correct weight and identity. All the manufacturing temperatures mix speeds and mixing times were within acceptable ranges. In-process appearance and specific gravity test results were all within acceptable ranges. A review of the solution filtration documentation confirmed that all filters and Water for Injection (WFI) were used within their expiration dates, and that all the filtration times, pH results, and pressure specifications were met. The manufacturing processes of raw material usage, solution formulation and filtration were all found to be acceptable. All manufacturing parameters met established requirements. A log is maintained throughout the manufacturing process of the amount of elapsed time that the product is out of refrigeration. A review of the elapsed time tracking logs confirmed that all times were within allowable limits. PACKAGING BATCH RECORDS: Complete -Acceptable. The review of the packaging record confirmed that all in process checks, all line startup and end of batch challenges, and all line clearance and cleaning activities were completed satisfactorily. Audits are performed on the finished packaged units by Packaging Operations personnel at regular intervals throughout the final packaging process.

During the audits, inspectors visually check the appearance of the finished product for defects. The Pfizer-BioNTech COVID-19 Vaccine vials are loaded into trays containing 195 vials each. Five trays are then banded together into a bundle. The vaccine requires ultra-low temperature freezer storage. Prior to loading, freezer temperatures were verified to between -67°C and -73°C. Freezer shelves were then loaded with bundles of product. During the freezing phase, which occurs 60 hours after loading, the temperature of the freezers is monitored. If the temperature is warmer than the previously recorded temperature, supervision is notified. Additionally, after the freezer temperature drops below -60°C, the temperature recorded may be warmer due to the freezer operation caused by the freezer cycling. This is acceptable. A review of the log for the reported batch confirmed that all freezer temperatures acceptable. Samples are then stored until the product is released for distribution.  LOT HISTORY: Complete - Acceptable. The results of all tests and inspections met required specifications at the time of release for distribution on 31Jan2021 Reserve Sample Evaluation: Rsrv. Sample Evaluation Reqd?: No. Rsrv. Sample Eval. Rationale: Visual examination of a reserve sample would not be expected to indicate the potency of the drug product. A reserve sample was not sent to the QC-lab to determine the amount of active ingredient since the complaint was received within six months of the release date of the involved batch. The results of all analytical tests performed at the time of lot release were confirmed to be within registered specifications. All available stability results for this product were within registered specification and stability studies (including accelerated studies) are ongoing for this product.
