The novelty of this (not captured in the headline) is that the man received non-resistant stem cells .

I believe in all previous cases the donors had mutations of the CCR5 gene which made them resistant to HIV.

Second sentence from the article:

> Significantly, he is also the second of the seven who received stem cells that were not actually resistant to the virus, strengthening the case that HIV-resistant cells may not be necessary for an HIV cure.

Yes, but why read the first paragraph of an article when you can write a comment to demonstrate your knowledge and ignorance simultaneously?

As the sentence right below the title says:

> A handful of people with HIV have been cured after receiving HIV-resistant stem cells – but a man who received non-resistant stem cells is also now HIV-free
