Doctors in Berlin are reporting that they cured a man of AIDS by giving him transplanted blood stem cells from a person naturally resistant to the virus.
But while the case has novel medical implications, experts say it will be of little immediate use in treating AIDS. Top American researchers called the treatment unthinkable for the millions infected in Africa and impractical even for insured patients in top research hospitals.
Now, admittedly, this article is pretty pessimistic about the practicality of using this treatment on everyone with AIDS, saying that it's just much too expensive and hard to find donors, but I think this is still absolutely incredible news.
I'm not a doctor (what's the right acronym for that? IANAD? hmmm...), but to me this is saying that we might be lots closer to a vaccine to one of the most horrible diseases of our time... a situation well worth celebrating.
