To build public trust and confidence in innovative products like mRNA vaccines and therapies, they must be of good quality, safe and effective. To address the need for a common set of methods for determining mRNA quality—including verifying the identity of the drug substance, controlling impurities and measuring content for dosing—USP is developing a set of analytical methods to support developers, manufacturers, regulatory agencies and national control laboratories worldwide.

USP welcomes public comments on Analytical Procedures for mRNA Vaccines Quality - 2nd Edition.
