COVID-19 vaccine(QTP104)

Next-generation mRNA COVID-19 Vaccine QTP104

  • QTP104 is a next-generation mRNA vaccine (repRNA: involved in self-amplification mRNA) encoding the Spike(S) protein of SARS-CoV-2. repRNA is capable of inducing a strong immune response with a smaller amount than simple mRNA vaccines by inserting replicase that is involved in self-amplifying. In addition, it has the advantage that there is no PEG-related allergic side effect by using LION formulation that doesn’t contain PEG components as a delivery material.
  • *LIONs: Lipid Inorganic Nanoparticles

Mechanism of Action

RNA encoding spike protein delivered to immune cells through LNP technology (LION)

  • Like the simple mRNA vaccine, QTP104 induces the antigen, which leads to the formation of antibodies. repRNA has the advantage of more antigenic production than simple mRNAs by replicase.
