In this addendum to Phys. Rev. D 95, 054018 (2017)PRVDAQ2470-001010.1103/PhysRevD.95.054018 we recompute the rates for the decays of the Higgs boson to a vector quarkonium plus a photon, where the vector quarkonium is J/ψ, (1S), (2S), or (3S). We correct an error in the Abel-Padé summation formula that was used to carry out the evolution of the quarkonium light-cone distribution amplitude in Phys. Rev. D 95, 054018 (2017)PRVDAQ2470-001010.1103/PhysRevD.95.054018. We also correct an error in the scale of quarkonium wave function at the origin in Phys. Rev. D 95, 054018 (2017)PRVDAQ2470-001010.1103/PhysRevD.95.054018 and introduce several additional refinements in the calculation.
