  We comment on the paper ``Remarks on flavor-neutrino propagators and
oscillation formulae'' [Phys. Rev. D64, 013011 (2001)].
  We show that the conclusions presented in that paper do not apply to the
exact field theoretical oscillation formulae obtained in the BV formalism (for
three flavors) which are free from the dependence on arbitrary mass parameters,
account for CP violation and reduce to the usual quantum mechanical
(Pontecorvo) three flavor oscillation formulae in the relativistic limit.
