    "abstract": "We study the effect of vacuum polarization in nuclear reactions of\nastrophysical interest. This effect has the opposite sign compared to the\nscreening by the atomic electrons. It is shown that vacuum polarization further\nincreases the longstanding differences between the experimental data of\nastrophysical nuclear reactions at very low energies and the theoretical\ncalculations which aim to include electron screening, albeit by a small amount.",
