WHO Guidelines for Stability of DNA and mRNA Vaccines Laboratory Testing Service: A Comprehensive Guide

The stability of DNA and mRNA vaccines is a critical aspect of vaccine development, manufacturing, and distribution. To ensure the efficacy and safety of these vaccines, the World Health Organization (WHO) has established guidelines for their stability testing. These guidelines are based on international standards, including those developed by the International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), the European Committee for Electrotechnical Standardization (CENELEC), and others.

International Standards

The following international standards are relevant to DNA and mRNA vaccine stability testing:

  • ISO 13485:2016 Medical devices Quality management systems Requirements for regulatory purposes

  • ASTM E2599-10 Standard Guide for Stability Studies Related to Applications of Pharmaceutical Products

  • CENELEC EN 62304:2006 Medical software Software life-cycle processes

    • National Standards

    In addition to international standards, national standards also play a crucial role in DNA and mRNA vaccine stability testing. For example:

  • USP <1070> Stability Testing of Drug Substances and Products

  • EU GMP Annex 1 Manufacture of Sterile Medicinal Products
