Moderna Rises 6% Despite GSK Moving Rival mRNA Flu Vaccine to Phase III
Moderna (MRNA) rose 6% to $148.32 as GSK (GSK) advanced its mRNA flu vaccine to Phase III, seen as platform validation. Moderna's melanoma trial success and BioNTech (BNTX) also benefited. Jefferies cautioned on mRNA therapy success across solid tumors. GSK gained 0.7% to $50.60.
