GSK begins its Phase III efficacy trial for FLUm3HA.b-3NA in September 2026.
GSK announced plans to advance the vaccine candidate into a Phase III trial starting in September 2026. The milestone is met when the trial officially doses its first participant.
Across 6 frontier models answering independently, the panel is barely on the yes side: the median is 63%.
They do not agree: Qwen puts it at 78% and DeepSeek at 12%, 66 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Nothing is settled until 14 Oct 2026, when the outcome is checked against sources and every number above gets a permanent score.
