• A novel mosaic-8b nanoparticle vaccine is under development to provide broad cross-reactive immunity against known and future sarbecovirus strains, enhancing pandemic preparedness.
• The vaccine targets conserved regions of the receptor-binding domain (RBD) shared by all SARS-like betacoronaviruses, aiming to overcome the limitations of current vaccines due to viral mutations.
• Pre-clinical research indicates the mosaic-8b vaccine triggers robust immune responses, even after prior SARS-CoV-2 exposure, generating broadly cross-reactive antibodies.
• Engineering biology CRDMO Ingenza has partnered with other organizations to formulate the vaccine, utilizing microbial platforms to reduce development time and costs.
