“He got the antibody treatment and within 24 hours was almost completely symptom-free.”
What did the antibody treatment consist of?
I don't know. My wife does most of the communications with them.
With people, especially family even more so than friends, getting accurate, detailed info on medical issues is problematical at best.
I have observed that many (most?) people do not really dialog with their doctor or ask questions. They also don't read up on what is being given to them. My BIL and his wife never question their doctor about anything. They take everything they hear in his office as the gospel.
Back to your initial question, I assumed the treatment was a standardized protocol with perhaps the only variations being dosage based on weight and or sex. They live in Florida BTW.
