WebAntigens and the Adaptive Immune Response. Adaptive immunity occurs after exposure to an antigen either from a pathogen or a vaccination. The adaptive, or acquired, immune response takes days or even weeks to become established—much longer than the innate response; however, adaptive immunity is more specific to an invading pathogen.
