David Whalley, via twitter asked:
Are humans evolving to become resistant to HIV?
We put this question to Peter Kwong from the National Institute of Allergy and Infectious Diseases in Maryland...
The answer is yes in some ways in that if enough people die off, they will evolve to be resistant, but hopefully, we don't have to go through a lot of death to have that. Hopefully, we’ll be able to come up with a vaccine and just eliminate the virus that way.
