Subject: Why does our body not mount an immune response against our own antbodies.

Our body produces antibodies in response to foreign antigens.
These antbodies are then themself very potent immunogens. Since 
these molecules are new to the body they should not be recognised 
as self.Thus the body should mount an immune response against these 
primary antibodies(i.e. produce antibody against this antibody.
Further more similarily this secondary antibody should again   elicit
a further immune response.And this chain should continue.Which is an 
unending and impossible task.Why does it not happen.
