The company has focused on two main aspects within this platform: the engineering of optimized mRNA constructs and the development of proprietary delivery systems.

CureVac’s engineering efforts center on the use of optimized mRNA, rather than chemically modified variants, to maximize translation efficiency while preserving safety and immunogenicity profiles. The proprietary optimization process tailors the mRNA’s coding regions and non-coding regions (such as untranslated regions, or UTRs) to improve protein expression levels, maintain stability, and ensure extended intracellular presence. This fine-tuning of sequence elements ensures that even at lower doses, the mRNA molecules produce sufficient levels of protein to trigger a protective immune response. In essence, the platform transforms mRNA into a highly efficient and reliable tool, capable of instructing cellular machinery to produce antigenic proteins or therapeutic enzymes as needed—a capability that forms the backbone of both vaccine and therapeutic strategies.

Furthermore, CureVac’s second-generation mRNA backbone represents a leap forward in delivering sustained and high-level antigen expression. Enhancements in the non-coding regions have been shown to yield prolonged and improved mRNA translation kinetics, an attribute crucial in COVID-19 vaccine candidate development and seasonal flu vaccine exploration. This technological advancement is a direct response to the challenges inherent in mRNA instability and the need for robust protein production in a clinical setting. By optimizing the mRNA structure, CureVac is not only improving the performance of its products but also making considerable strides in reducing the manufacturing challenges—demonstrated by expanded production capacities at its Tübingen headquarters and European sites.

In addition to sequence optimization, CureVac invests heavily in refining its delivery vehicles—primarily lipid nanoparticle (LNP) formulations—that encapsulate the mRNA. These LNPs protect the mRNA from degradation in vivo and ensure efficient cellular uptake, thus playing a crucial supportive role in the overall R&D framework. Collectively, these efforts underscore a commitment to both the fundamental and practical aspects of mRNA therapeutic development, ensuring that the platform remains at the forefront of biopharmaceutical innovation.
