Dr Kelly is a physician , he has understanding of medicine , one can learn any specialty after studying different diseases for few months/years.
I feel that after reading about HIV and COVID for so long being in cydy , I will not embarrassed myself with the biggest specialists , and actually when I listen to some , I see that I am better then many.
And I believe that many not medical people , being here for few years , doing good DD , maybe consider a specialist in these diseases ...
Dr Kelly is learning about CCR5 and related diseases for many years now , I expect he is knowledgeable ..
Not as much as Dr Patterson , of course .
Dr Patterson study mostly CCR5 for the last 25 years..but there are things in medicine he will not know today, but afters spending few months on it he will , if ever needed...
All IMO.
