Ii-Key Platform Overview

The Ii-Key-SARS-CoV-2 vaccine is designed as a "Complete Vaccine" that has the potential to induce the T-Cell and antibody immune responses that can provide protective immunity with long-lasting immunologic memory against SARS-CoV-2 in a highly specific manner to ensure safety. Ii-Key is a platform technology enabled by the amino acid key sequence "LRMK" that is shared across the platform. The LRMK key sequence works by its ability to deliver any desired peptide epitope of interest directly to the MHC Class 2 complex on the surface of antigen presenting cells. Once a suitable target epitope is identified, an Ii-Key vaccine candidate is created by means of synthetic peptide synthesis, which produces a single linear amino acid chain that includes the Ii-Key sequence, a short inert linker sequence, and the target epitope of interest. In this way, the target epitope is delivered by the Ii-Key sequence directly to antigen presenting cells, resulting in an immune system stimulation.
