• mRNA-1010 demonstrated superiority on seroconversion rates for A/H3N2 and A/H1N1, superiority on geometric mean titer ratios for A/H3N2, and non-inferiority on geometric mean titer ratios for A/H1N1
• Non-inferiority was not met for seroconversion rates and geometric mean titer ratios for the influenza B/Victoria- and B/Yamagata-lineage strains
"While we did not achieve non-inferiority for the Influenza B strains which are more frequent in younger populations, we have already updated the vaccine that we believe could improve immune responses against Influenza B and will seek to quickly confirm those improvements in an upcoming clinical study thanks to the agility of our mRNA platform."
