Because Avant-Garden strengthens the immune systems defence considerably, donor-operated people must NOT use Avant-Garden, even if they find it useful to avoid infections in general.

People forced by their health to replace an internal organ like a kidney or a heart from a donor by an operation, must take certain medicines to reduce their immune systems defence to avoid that their organism rejects their newly operated donor-organ.

We have to make everyone aware of this so that the donor-operated people do NOT expose themselves to any risk by getting a too strong immune defence system, as strange as it may sound.
