Nothing new here. Sure they will mutate to avoid future drug death if they survive. Mind you they mutate before any drug hits them in order to ensure survival in a host. It's natural. parasites are masters in mutations. If parasites mutate to avoid your highly sophisticated TH2 'anti-done'... They can do same for any drug. But once again stop this silly claims reg end of the human existence. You clearly underestimate the human immune system it's damn good at doing one job with them... Keeping you alive. Be amazed that you are not dead yet. And stop PM me with some nonsense plz.
