Okay, this question is a little harder than the last one.

I'm writing (or at least trying to write) a next generation fic.

I believe that Clark's children would be able to catch diseases. This is because I believe Clark's inablity to catch diseases stems from his alien origin, not his invulnerablity. I think there is plenty of evidence for that in the show even though it is not a popular theroy in fandom.

Because of that, I also believe his children would respond to drugs, but sitll be
invulnerable to bullets, bombs, knives, etc.
However, as part of my A - Plot, I want their oldest daughter to encounter a virus that can't be cured easily. I chose anthrax because acording to my information, their is a a - born version. (Meaning she could encounter it and not realize it - plus I wouldn't have to worrry about how to pentrate the skin.) Besides that, the info says oral drugs only work before the symptoms show.

I don't want her using the oral drugs because it would be too easy. Besides, she would have to realize she encountered it.
The standard antrax treatment is with IVs. Since she is supposed to be invulnerable, that treatment should not work for her, unless they used kryptonie to pentrate the skin.

And that brings me to my problem. I would like her to be invulerable to kryptonite as well. First of all, it sounds more reasonable with the information in the story.
Second of all, using standard antrax treatments to treat this problem sounds to easy to me. I want there to be a few days where they really do believe she will die and they don't know what to do.
Therefore, I would like to find some other treatment for antraz that sounds plausible. Either another "real" treatment that is simply not popular, but would work in her case, or another treatment that would work in the LNC universe. (They do some strange things with science - cloning, etc.) But I want it to make sense that it could work.

The only idea I can come up with that is a medical treatment but could work with a woman invulernable to needles is radiation. But that doesn't make sense as a treatment for anthrax. See what I mean?

If there really are no other options, I will assume that kryptonite could penerate her skin, and they'll use standard anthrax drugs. I'm not willing to let my character die. But that's my last option, so I'm hoping someone can help me out here.


P. S. Thanks for those of you who answered my Swiss chocolate question
