SOP for Conducting Stability Studies for Combination Vaccines under WHO and FDA Guidelines

Procedure for Stability Testing of Combination Vaccines

1) Purpose

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

2) Scope

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

3) Responsibilities

Vaccine Development Team: Responsible for developing combination vaccine formulations and selecting suitable packaging materials.
Stability Study Team: Responsible for conducting stability studies according to approved protocols.
Regulatory Affairs Team: Responsible for ensuring compliance with WHO and FDA guidelines and submitting stability data to the relevant authorities.

4) Procedure

4.1 Protocol Development

4.1.1 Develop a stability testing protocol that includes parameters specific to combination vaccines, such as potency, antigen content,

sterility, and preservative efficacy.

4.1.2 Define 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 packaging for stability testing, ensuring that packaging materials are suitable for vaccine storage.

4.2.2 Store samples under specified conditions,

with continuous monitoring of environmental conditions.

4.3 Conducting Stability Tests

4.3.1 Perform stability tests at defined intervals, focusing on parameters critical to vaccine safety and efficacy.

4.3.2 Document all data accurately and ensure compliance with the approved protocol.

4.4 Data Analysis and Reporting

4.4.1 Analyze stability data to detect any trends or deviations that could impact vaccine quality and safety.

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