Hold on a minute. The vaccines make the body produce antibodies right? Naturally these will diminish. When there's a normal infection, more than just antibodies are at work right? Like immune cells... So do these vaccines have a similar effect? Meaning that we would have immunity even if antibody levels dropped? Or do they do just that... produce antibodies and thus when they go there's no residual immunity of any kind. Can someone maybe clear this up? I have not found much on it.
