  We consider the role played by subcritical bubbles during the electroweak
phase transition, estimate their average size, amplitude and formation rate
taking into account the crucial role played by thermalization. We also study
the influence of subcritical bubbles on the formation of critical bubbles in
the thin wall regime and show that, contrary to some recent claims, subcritical
bubbles do not affect the nucleation of critical bubbles in an appreciable way.
  From this fact we conclude that the electroweak baryogenesis scenarios
associated with a first order electroweak phase transition still remain an
attractive possibility.
