Polarization propagators are powerful theoretical tools that were first developed within the non relativistic regime and applied in atomic and molecular physics more than thirty years ago. Electric and magnetic molecular response properties are between that properties that were most studied with them. Whence they were generalized for being applied in a {it full} relativistic framework it became apparent their special role for describing the quantum origin of any molecular property and the coherence of both, their definition and the proposed aproximate solutions of the corresponding equation of motions. Then the finding of a QED based theory of polarization propagators was a natural generalization of the relativistic polarization propagator theory given that propagators summarises the quantum behavior of molecular systems.
