For the First Time in History Man Cured of HIV

1. The notion that a cure must be widely applicable is the foundation of clinical medicine, even with personalized medicine. You simply can't run clinical trials with a sample size of 1. Just because an individual treatment is tailored to the patient doesn't mean the process and plan of action is generated new each time. The OP is stating how there is no way to generate the 'curative' stem cells and the odds of them appearing in natural populations is extremely rare. This case is an awesome but exceptional situation, and is not a basis to claim a breakthrough in the fight AIDS. As a proof of principle, even anti-retrovirals show that an individual can be healthy post-infection.

2. There are no FDA approved therapeutics for disease that use bacteriophage, there is only some things as preservatives for meat. Most treatments of genetic disorders are generally nonspecific - they treat symptoms and gene therapy is still a developing field. Even in that case, the delivery vector is usually generalizable - usable in many patients with slight individual modification.

3. in vivo refers to in glass, or in an experimental set-up, this is most clearly not in vivo.

Anti-retrovirals only do so much - they have to be taken for the patient's whole life. This is different, they are claiming that HIV has effectively been eradicated in a living body, which just hasn't happened before. This isn't meant to be a clinical trial, it's the only living proof we have that we can kill all the HIV without killing the patient.

And you're mistaken about in vivo. In vivo = "within the living", in vitro = "within glass" (& "in silico" = "within silicon", ie. simulated on a computer).

Do you consider organ transplants to not be "cures" of any disease? I've yet to hear of even a potential method for growing vital organs from scratch, and even the methods using donor cells seem to lack FDA approval.

If you do believe that organ transplants can cure a disease, then there must be some threshold of donor commonness that divides organ transplants and this treatment. Where might that line fall?

The sample size has to be large enough for the results to have statistical significance. If something happens in the patient that never happens in comparable cases, and you have piles of information about suitable controls, then you can place a high certainty in the treatment being able to work. You don't have a success rate, but nobody's claiming one.
