  A hadronic vacuum polarization correction to the photon propagator is found
by using the Dubnicka-Meshcheryakov parameterization of the pion
electromagnetic form factor and new experimental data on the $e^+e^-$ hadrons
annihilation cross section. Then, the contribution from the hadronic vacuum
polarization to the muon anomalous magnetic moment and the Lamb shift in muonic
atoms are calculated.
