I am new to this site. My son is 10, and since getting strep in september is a different kid. he is finally on ivig which helps somewhat so far.. he's only gotten 2 treatments.. so when he does get strep his symptoms are milder and shorter. eventually, the ivig treatments should prevent the immune response to the strep, and i've also considered tonsillectomy.
but it does seem that you cant predict how a kid's immune system will respond to ANY antigen - vaccine, a virus, a food, etc.. so the key is to modulate the immune system. i'm still just learning myself, since my son has missed school and has not yet returned to his previous level of function.
