So will people surviving it as that also generates antibodies and curtails the lifetime of the virus. It’s possibly worse from the virus’ point of view as the antibodies will be less specific, having the whole virus as a target. Face it, it’s a hard life for a virus. If it’s too successful, people die and fail to spread the virus. Otherwise, immunity slowly builds up and restricts the spread. Unless it manages to alter itself to change host species or manages to harm the immune system.
