Nice.
I will agree that if this is true it is good news. The problem is that from the information I have seen (and I’ll look for it right after I post this) for an AIDS vaccine to be really useful it MUST be 100% - preventing each and every host cell in the body from ever being invaded. That has never been true with any vaccine. This is why I must be colored very skeptical about the usefulness of this solution.
I don't know how accurate this article is since I'm not a physician, but it sounds very plausible. If so, even a very good vaccine for this type of virus is only going to be marginally useful in the long run.
