We review the status of the calculation of next-to-next-to-leading order corrections to large angle Bhabha scattering in pure QED.

Abstract
We review the status of the calculation of next-to-next-to-leading order corrections to large angle Bhabha scattering in pure QED. After discussing the electron-loop and photonic corrections, we focus on the recently calculated two-loop virtual corrections involving an heavy-flavor fermion loop. We conclude by assessing the numerical impact of these corrections on the Bhabha scattering cross section at colliders operating at a center of mass energy of about 1-GeV. © 2008 Elsevier B.V.
