The vacuum-polarization (VP) corrections to rates for nuclear-fusion reactions in the [ital pp] chain and in the CNO cycle are calculated. For the reactions of particular importance to the solar-neutrino problem, the [sup 3]He([sup 3]He,2[ital p])[sup 4]He, [sup 3]He([alpha],[gamma])[sup 7]Be, [sup 7]Be([ital p],[gamma])[sup 8]B, and [sup 14]N([ital p],[gamma])[sup 15]O reactions, we find the magnitude of the effect to be less than 2%. The effect of VP on all the other reaction rates is expected to be of a similar order of magnitude. We discuss how these results affect the predicted fluxes of solar neutrinos.
