Procedure for Stability Testing of Combination Vaccines

1) Purpose

The purpose of this SOP is to define the procedures for conducting stability studies for combination vaccines in alignment with WHO and FDA guidelines. This ensures that combination vaccines maintain their quality, potency, safety, and efficacy throughout their intended shelf life.

2) Scope

This SOP applies to all personnel involved in the stability testing of combination vaccines, including those working in formulation development, quality control, and regulatory affairs.

3) Responsibilities

Vaccine Development Team: Responsible for creating combination vaccine formulations and selecting appropriate packaging materials.
Stability Study Team: Responsible for conducting stability studies as per the approved protocols.
Regulatory Affairs Team: Responsible for ensuring that stability data complies with WHO and FDA requirements and is submitted to the appropriate regulatory bodies.

4) Procedure

4.1 Development of Stability Protocol

4.1.1 Develop a stability testing protocol that incorporates parameters crucial for

combination vaccines, such as potency, sterility, preservative efficacy, and antigen content.

4.1.2 Specify storage conditions (e.g., refrigerated, frozen) and testing intervals (e.g., 0, 3, 6, 12 months) according to WHO and FDA guidelines.

4.2 Sample Preparation and Storage

4.2.1 Prepare samples in their final container-closure system for stability testing, ensuring packaging suitability for vaccine storage requirements.

4.2.2 Store samples under controlled conditions, ensuring continuous monitoring of temperature and humidity.

4.3 Execution of Stability Tests

4.3.1 Perform stability tests at each defined interval, focusing on critical parameters that impact vaccine safety, potency, and efficacy.

4.3.2 Accurately document all data and ensure compliance with the approved protocol.

4.4 Data Evaluation and Reporting

4.4.1 Review and analyze stability data to detect any trends or deviations that could compromise vaccine quality or effectiveness.

4.4.2 Compile a comprehensive stability report for regulatory submission, including all findings, results, and conclusions.
