> Wow, I didn't even know that you can be immune to HIV. HIV contains some code which use to convert a cell to be a zombie (afaik that cell's vulnerable place in cell's DNA is called CD4). But some people has that part of cell's DNA slightly different, not better not worse but different, therefore not vulnerable to that special code. The HIV for different cells is yet to be discovered. When we will have understanding of how to change the DNA code (implementing is really easy tbh), than any malintentioned person might develop new viruses shaping some known ones to be even more destructive.
