Hi. Newbie question. What stops a vaccine from triggering the very illness it's supposed to prevent? It's my understanding that viruses like Ebola aren't really alive, but are able to trick host cells into replicating the virus's DNA. How then do you "kill" such a virus so that it's dead form triggers the creation of antibodies but not the illness you're trying to prevent?

Thanks.
