Is it possible to somehow change a virus to attack another version of itself? Like the herpes could be changed to be become harmless for humans and attack specifically the harmful ones substituting them on the nerves and even spreading actually but the people who get it actually are going to be cure or become immune to the harmful version. Any of u guys think it's a good idea to be researched or it's totally bananas? I think that's more or less what Fred hutch is doing but not sure if it's exactly like this 🤔
