I could be wrong but I'm not sure the rabbies vaccine is a good example. Because even though it is effective after rabbies enters the body I'm not sure it is effective after the initial immune response which may only occur once the virus reaches the central nervous system. Not saying you're wrong, I just genuinely don't know if an immune response is triggered by the virus before that.
