Are Half-Elves immune to the paralyzing property of a Ghoul’s Claw action?


The Ghoul’s Claw attack in the Monster Manual (p.148) has the rider of forcing a save or paralyzing a creature if the target:

… is a creature other than an elf or undead …

My question is this:

Is a Half-Elf required to make the saving throw, or is it immune, like Elves and Undead are?
