Question about Candida immune stimulating shot

Has anyone had any luck getting their doctor, allergist, etc. getting an candida extract/immune stimulant shot? They read as very helpful with activating the immune system against candida but most doctors aren't familiar with them from what I can tell, functional or mainstream, etc. If you've had experience with said shots, how did you get your doctor to administer them? Was it a mainstream or alternative doctor? Thanks
