Explicitly finite equations are derived with the adaptation of the renormalization method of van Hees and Knoll [H. van Hees, J. Knoll, Phys. Rev. D65, 025010 (2001)] to the case of non-vanishing field expectation value. The set of renormalization conditions used in this method leads to the same set of counterterms obtained recently in A.
