Antibodies?

Can an infusion of antibodies make you herx?

Can you further explain so that you can get a solid response to your question? What specific antibodies are you referring to?

Is it IVIG you are getting?

If so, sometimes LLMD's give that to their patients. I'm sorry I don't know much about it...but it is used for lyme patients sometimes.
I remember reading an article that a pediatric LLMD stated he uses IVIG sometimes. I will see if I can find it.

I don't know if it mentioned herxing from it.

Actually, in your case I'd say to be cautious with it, and be prepared to herx - although you may not. Why DoD I say this? Because your immune system will get a boost, which also means it will likely try to fight the infections more, creating more toxins, which is what causes us to herx.

I assume you have been getting these for a while now? How did last month's IVIG go? That should tell you quite a bit.

Try increasing your detoxing, that may be the key to tolerating the treatments better.

I'm curious though, if you don't mind. I was wondering if this is something you acquired "at birth" or if it's something that developed later in your life? The reason I'm asking is because even if you got it at birth, you may be able to deal with it easier after you treat Lyme and company, and of course, if you got it later, it could be due to Lyme, or treating Lyme may make a big impact on how well you do afterwards.
