FAE/Thermobaric/Novel Explosive (NE) warheads work by a combination of high blast overpressure & residual vacuum effects, with secondary incendiary effect.

There is no vacuum effect. That is an urban legend. The oxigen could be almoste burend out, but the result nowhere closed to vacuum. There is some negative overpressure, enough to shake a human though, but
"The primary injury mechanisms are blast and heat, with secondary effects through flying fragments and toxic detonation gases"
