mNEXSPIKE is designed to be different from Spikevax® (COVID-19 Vaccine, mRNA)1,2
mNEXSPIKE encodes immunodominant epitopes of the COVID-19 spike protein, thus incorporating a smaller mRNA molecule compared to Spikevax, which encodes for the entire spike protein.1,3
mNEXSPIKE demonstrated a numerically higher rVE against COVID-19 vs Spikevax in a phase 3 noninferiority trial1*
Higher antibody response and seroresponse rate led to a greater immune response compared with Spikevax.†
Clinical study of mNEXSPIKE was not designed to evaluate superiority.
In a subgroup analysis of adults aged ≥65 years, mNEXSPIKE demonstrated a numerically higher rVE vs Spikevax1*
