Any nuclear reaction producing a photon with an energy above $2m_e$ must be supplemented by the corresponding reaction where the final state photon is replaced by an electron-positron pair. We find that pair production brings a typical $0.2 \\%$ enhancement to photon emission rates, resulting in a similar size corrections to elemental abundances. The exception is $^4{\\rm He}$ abundance, which is insensitive to the small changes in the nuclear reaction rates.
