There is a huge difference between passive immunity, like Adâh has, and active immunity, like a plague survivor has. Active immunes have anti-bodies that can help immunize others. That is probably not the case with Adâh’s blood. Adâh’s systems simply ignore any disease vector. This does not prevent her from being a carrier, something that Miko was worried about in Starfall.
