No, "Red Alert" is called when there is an attack imminent, incoming weapons detected, enemies sighted.

So a macrophage on "red alert" would be reacting to an active infection or disease.

Sure, and this vaccine goads the macrophage into that state, putting it on "red alert", without there actually being an infection.
