This document outlines definitions, tests, specifications, and procedures for vaccines, immunoglobulins, diagnostic antigens, and their packaging and stability studies. It defines vaccines, immunoglobulins, and diagnostic antigens. It describes physico-chemical, biological activity, analytical, and other tests done during development and production. It lists specifications that must be provided for the final product and additional specifications for oral liquids and parenterals. It also covers batch manufacturing records, packaging material specifications, and stability studies on the finished product.

Immunological products quality control
Definitions A vaccine is a product intended to stimulate the immune system in the prevention, amelioration or treatment of disease or infection. A vaccine may be a live attenuated, preparation of bacteria, viruses or parasites, inactivated (killed) whole bacteria (bacterins) viruses or parasites, living irradiated cells, crude or purified fractions of organisms, including those derived from recombinant DNA in a host cell, synthetic antigens, polyneucleotides (eg. plasmid DNA vaccines), inactivated bacterial toxins (toxoids), or a combination of the above.
Definitions Immuno-globulins and antisera are preparations of antibodies of human or animal origin respectively intended to treat or provide immediate protection against infections. A diagnostic antigen is a crude or purified fraction isolated from microbial culture and intended for in vivo detection of an existing specific immune response (antibodies).

1- Physico-chemical tests: 􀂾 identity Protein determination (Bradford, BCA) UV/Vis spectroscopy ELISA HPLC (SEC) and FPLC (Affinity) Potency Tests: Bioactivity assays Specific binding assays. General Tests: Appearance pH Osmolality Ion chromatography
1- Physico-chemical tests: 􀂾 purity HPLC (SEC, IEC, RP) Endotoxin content (LAL-test) Host cell protein assay (Threshold® and ELISA) Host cell DNA assay (Threshold®) Host Cell Contaminants. Bioburden Virus testing Residual solvents (GC) Sterility Determination of water content
2-Biological activity tests  Specific identity testing such as ELISA  Cytometric analysis  Neurovirulence testing  Serotyping  Electrophoretic typing  Inactivation studies  Neutralization assays  Titrations  Immunogenicity  Potency
4- Summarized specifications of the final product the acceptable limits of all the physical, chemical, biological and microbiological parameters. A full description of analytical and other control procedures carried out to ascertain the final product specifications stated above shall be given. Where analytical procedures in various parts of the application coincide, these procedures may be described fully in one part and may be subsequently referred to in other parts, provided that the relevant page and paragraph are clearly identified.
Specifications and test methods for all dosage forms 1. Description 2. Identity: the test method should proven to be specific and sensitive for active ingredient(s) 3. Potency: the test method should be proven to be specific, sensitive and stability indicating for active ingredient(s) 4. Impurity limits: to identify and determine the level of degradation products of active ingredients, and active ingredient – excipient interaction impurities
Additional specifications and test methods for oral liquids  Uniformity of content and mass  pH  Microbial limits  Antimicrobial preservative content/preservative efficacy test  Antioxidant preservative content  Extractable from primary container  Alcohol content  Dissolution for suspensions  Redispersibility  Specific gravity  Water content
Additional specifications and test methods for Parental Uniformity of content and mass  pH  Sterility Endo-toxins/pyrogens  Particulate matter  Water content  Antimicrobial preservative content/PET  Antioxidant preservative content  Extractables  Functionality of delivery systems, eg. syringeability for prefilled syringes  Osmolality  Redispersibility
5-Batch Manufacturing Records (BMR) From the release of raw materials to release of final product for marketing, shall be submitted including QC reports. Batch records for one particular batch should include: 􀂾 supplier’s certificates of analysis of raw materials 􀂾 adsorption records 􀂾 formulation records 􀂾 filling records 􀂾 lyophilisation records 􀂾 packaging records 􀂾 labeling records 􀂾 reconciliation records 􀂾 manufacturer’s Certificate of Analysis of the finished product. 􀂾 a certified copy of a State Batch Release Certificate for the batch, including results of purity, potency and efficacy testing
6- Specifications of the packaging material The following information shall be provided: 􀂾 description of the container and closure system including primary(inner)and secondary(outer) packaging. 􀂾 The chemical identity of materials for each component of the system 􀂾 Detailed specifications and tests for primary (immediate) packaging components
Evidence of suitability of the container and closure system for the finished product: •compatibility of primary packaging components with the finished product * performance of the system in drug delivery, eg. actual volumes of teaspoons and extractable volumes of vials and ampoules Such specifications and tests shall be as per the British Pharmacopoeia, European Pharmacopoeia, or United Pharmacopoeia, or in-house, and certificates of analysis shall be provided as proof that the packaging conforms to specifications.
