It is quite easy to counteract the virus. The challenge is not causing more collateral damage to the body in the process. We also do have other mechanisms. One of the simplest treatments is convalescent plasma, where you take blood plasma from people who have recovered from a virus (and presumably have antibodies) and give it to an infected patient. This is not telling the immune system how to react in the way a vaccine does; it is bypassing the immune system to provide anti-bodies directly (of course, after the anti-bodies attach, normal immune system responses take over). A team of Isreali scientiest have produced artificial anti-bodies that serve the same function without relying on someone else's immune system to produce [0]. There are also a host of anti-viral drugs designed to interfere with with various processes used by virus. For instance, ribavarin resembles adenoside, which is a one of the building blocks of RNA. It can therefore inject itself into the virus's RNA during replication and cause fatal mutations in the virus. > it seems they are nothing more than mechanical devices. Chemical devices would probably be more accurate. Even determining what shape they have is an difficult computation problem (protein folding). Even if you know that, you have to consider how it would interact with every other chemical process in the body that it comes into contact with.
