Our immune system are able to distinguish viruses when antigens on the surfaces of virus particles bind to immune receptors that are meant for these antigens.Similarly as a lock recognizing a key. After an infection, the body produces many more of these virus-specific immune receptors, which prevent re-infection by this particular strain of the virus and produce acquired immunity.
