As I understand it, "hidden" is a relative thing. Before exposure one's immune system doesn't know what to look for, after exposure, and immune response, one's T and B cells have a much better chance. That's why denovo immune response to an epitope may not be sufficient, but once the immune system has been 'exposed' or 'educated' the response is much more specific. There are two parts to the immune system, innate, basically structural, and adaptive (T's and B's) that can be primed with certain factors to create a very precise response. The long term nature of immune response is dependent on those cells, which come in number of different 'flavors'. Tissue Resident Macrophages hang out in the area of initial infection, waiting for "that guy" to show up again. They can sit relatively dormant for years. I don't want to mislead, our understanding of the long term memory function of the immune system isn't completely understood. And so we don't know how long a given immune response will last, at least not yet. Does that help? I'm not an immunology prof, or researcher, so I may not have been clear.
