8.2.2 Acquired Immunity
Acquired immunity, on the other hand is pathogen specific. It is characterised by memory. This means when our body encounters a pathogen for the first time it produces a response called primary response which is of low intensity. Subsequent encounter with the same pathogen elicits a highly intensified secondary or anamnestic response . This is ascribed to the fact that our body appears to have memory of the first encounter.
