Sampling is an operation to select a portion of products for the purpose of testing in the laboratory.

VBM-LSD carries out sampling of vaccines and other biologics with a procedure that is well documented to show batch number, date and place of sampling, sampling method used, description of product sampled, notes on possible abnormalities, other observations, and name and signature of inspectors and consignee.

VBM-LSD carries out sampling of vaccines and other biologicals in collaboration with Ports inspectorate directorate.

A systematic random sampling is adopted on a batch-by-batch basis for the same product and every form of bias is eliminated.

VBM-LSD personnel are adequately trained in the practical aspects of sampling and qualified to perform sampling operation with sufficient knowledge of biological substances making them well equipped to execute the work effectively and safely.

Samples are kept in cold boxes to maintain cold chain of product all through the period of transportation to the laboratory.

  Quality documents required from Consignee during sampling include:

• Certificate of Analysis (CoA): The CoA lists tests performed on a particular sample with the results obtained and the acceptance criteria applied, followed by an indication of whether or not the sample complies with specification. The compendia method used for the test should also be shown.
• Summary lot protocol: This document describes the key steps and critical test results at each step of the production process.
• Certificate of Release from the NRA where the product originates from.

Lot release is a basic requirement in the control of vaccines. It is to confirm the production of each batch or lot is consistent since every lot is distinct.

Biologicals are inherently variable due to the nature of the starting materials, manufacturing process and test methods. Post licensing monitoring of vaccines and biologics involves lot by lot release. The objective is to verify that a batch is in conformity with the approved specification and that it meets the product license or market authorization. The importance is that it ensures that each batch of the vaccine are safe and potent; in addition to GMP Inspection, Post Market Surveillance, and assurance of proper storage.

The documents required for lot release of a product include.

1. Summary Lot Protocol (for protocol review)
2. Certificate of Analysis
3. Certificate of Release from the NRA where the product originates from.

VBM-LSD issues lot release certificates on imported vaccines after analysis and document review.

• Lot Release for 2022
• Lot Release for 2021
• Lot Release for 2020
• Lot Release for 2019
• Lot Release for 2018

Biologics are very specific and highly effective medicinal products derived from living organisms and cannot be produced by chemical means like drugs. Some biologics are extracted from living systems (e.g. blood), others are products of recombinant DNA technology like monoclonal antibodies etc.

Vaccines are biological substances that provides active acquired immunity to a particular infectious disease caused by bacteria and viruses.

Vaccines are administered to a large number of healthy adults and infants; this helps to protect individuals from several life threatening diseases. In Nigeria, vaccination has greatly reduced the burden of infectious diseases and NAFDAC ensures the safety and efficacy of Biologics including vaccines before use.

The public is advised to always consult with healthcare providers to determine the vaccines and biologicals suitable for use and fit for purpose. Vaccines and biologicals should be administered by certified trained personnel.

Patients should report any adverse event following immunization to healthcare provider immediately.

The general public should report all activities that contravene the Agency’s mandate of safe guarding the health of Nigerians to NAFDAC authority.

Healthcare providers should always ensure that only vaccines and other biologics, certified safe and efficacious by NAFDAC are administered to patients. Healthcare providers should forward all reports of adverse events following immunization to the Pharmacovigilance unit of NAFDAC.Healthcare providers should ensure proper cold chain monitoring along its distribution line.

Healthcare providers should interface with designated NAFDAC staff on issues concerning NAFDAC. Please avoid use of external NAFDAC consultants for the purpose of NAFDAC accreditation as their appointments have been revocated.

The role of NAFDAC in safeguarding the health of the nation through immunization activities is to ensure that only safe and efficacious products are administered to the populace. This mandate is implemented through inspection, registration and appropriate laboratory tests alongside document review(certificate of analysis, certificate of release from regulatory authority of country of origin and summary lot protocol) to assure that vaccines and biologics to be used nationwide for immunization are appropriate, safe, of good quality and satisfactory for the intended users.

The stipulated time for analysis of Vaccines/biologicals is 8weeks (working days only)

CONDITIONS FOR REJECTION OF PRODUCTS

• Products with compromised cold chain system
• Submission of insufficient products as per sample guide
• Non-availability of required documents
• Poor Labelling of products
• Disparity in product information and required documents information.

All enquiries concerning sample submitted for analysis is made at the Directorate sample was submitted, which can then be forwarded to the Director or office of the Head of Laboratory.

The Head of Laboratory receives all complaints and ensures the resolution of all complainants related to laboratory activity. Complaints should be resolved within 45 working days.

Documents submitted during sampling of vaccines are

• Certificate of Analysis (COA)
• Certificate of Release (COR) from NRA of country of Origin (Vaccine)
• Summary Lot Protocol for production and testing (vaccines).

TRF stands for Test Request Form.  It is a form issued to the customer to documents samples submitted to the laboratory and also to indicate test parameters being requested for the sample submitted by customers.

Vaccines should be stored and transported to the laboratory as stipulated on the product label by the manufacturer

No, except when there are issues of controversy after going through the appropriate channel.

Laboratory Risk-Based Testing &Categorization.
