SGA - one quick question regarding the Hoffan-drug

Yes, I know, I could do the research myself but perhaps somebody out there already knows it, so asking won't hurt. The Hoffan-drug who turns people into poison for the Wraith (provided the medicated person survives) - is the effect hereditary or limited to the person who was treated? Meaning: Will children of Wraith-immune parents also be immune to feeding by birth and poison a Wraith who tries?
