Moderna (MRNA) stock jumps after-hours as CEO signals pullback in new vaccine trials
Moderna shares jumped 4.2% to $51.87 in after-hours trading Thursday after CEO Stephane Bancel said the company will halt new late-stage vaccine trials, citing resistance from U.S. officials and an unreliable U.S. market. The move follows weak COVID vaccine demand and comes as Moderna and Merck reported their experimental cancer vaccine cut melanoma recurrence or death by 49% over five years in a mid-stage study.
