  Cosmology with non-perturbative quantum corrections resulting from torsion is
considered. It is shown that the evolution of closed, open and flat Universes
is changed because of the presence of a non-zero dispersion of quantum torsion.
The evolution of a Universe with quantum torsion and with one type of average
curvature can be similar to the evolution of a Universe without quantum torsion
and with another type of average curvature. For the description of the
non-perturbative quantum torsion, a vector field approximation is applied.
