Novavax Shares Gain 19% in Short Week
Novavax Inc. heads into the week after a jump over four sessions. U.S. markets were closed over the weekend. The stock finished Friday at $10.97, up 6.3% that day, gaining around 19% since May 22. Nasdaq stayed shut Monday for Memorial Day, so trading will run on a shorter schedule. This matters now because the U.S. Food and Drug Administration told approved COVID-19 vaccine makers Friday that shots for the 2026-2027 season should use the JN.1-lineage XFG variant in a monovalent vaccine — a single-strain shot.
