What the paper reports
This review compares self-amplifying and circular RNA vaccine architectures, expression kinetics, delivery approaches, and immune responses. It discusses the different reasons these platforms may extend antigen production or reduce dose requirements, alongside manufacturing, purity, reactogenicity, and regulatory challenges. It is a synthesis of heterogeneous preclinical and early clinical evidence, not a new head-to-head trial establishing superiority over conventional mRNA vaccines.
Why this paper is included
Useful for comparing next-generation RNA platforms; heterogeneous studies and limited clinical data prevent broad claims of superior durability or safety.
The interpretation above is analysis, not a conclusion attributed to the original source.
