  We have previously shown that the singularity in a Schwarzschild black hole
of stellar or larger mass may be avoided in a semiclassical manner by using as
a source of gravity the stress-energy tensor (SET) corresponding to vacuum
polarization of quantum fields, with a minimum spherical radius a few orders of
magnitude larger than the Planck length. In this note we estimate the nonlocal
contribution to the total SET due to particle creation from vacuum. We show
that this contribution is negligibly small as compared to vacuum polarization
and does not affect the previously suggested scenario.
