We solve the Klein-Gordon equation for a massive, non-minimally coupled
scalar field, with a conformal coupling, undergoing cosmological evolution from
a radiation-dominated phase to a future sudden singularity. We show that, after
regularisation, the energy of the created particles is zero and the
back-reaction from quantum effects does not change the evolution of the
universe near the future singularity and cannot prevent the finite-time sudden
singularity.
