ok, let me see if i get that straight. you claim that
	(A) AZT does not help HIV+ people
	(B) AZT is harmfull and causes AIDS.

but at the same time, you cite a study that shows an at least transient
positive effect on people during primary HIV infection  just to dispute
when AZT dosage was changed ? doesn't that strike you a weired ?

p.s. I suspect the key word here is "primary infection". the initial
viremia results in much higher plasma titers (RT-PCR) than the chronic
viral titers. for clinical benefits, you want to hit the virus harder than
in normal therapy. i don't know the exact date the dosage was changed, but
i think chronically infected patients received the lower dosage discussed
here since the early 90s. so find some more studies to back your beliefs
(they are not opinions).
