We use a recent result for the graviton contribution to the one-loop vacuum polarization to solve the effective field equations for dynamical photons on a de Sitter background. Our results show that the electric field experiences a secular enhancement proportional to the number of inflationary e-foldings. We discuss the minimum effect this establishes for primordial inflation to seed cosmic magnetic fields.
