The electromagnetically induced transparency (EIT) with squeezed vacuum was investigated. The control light with squeezed vacuum resonant on the 87Rb D1 line was injected into an optically dense rubidium gas cell. While using the control light, the absorption was found to decrease up to 31% at the zero-magnetic field, and the width of the transparency window was found to be 2.6 MHz. The restored squeezing to -0.18±0.03 dB with the control light indicated the change of the atomic medium to transparent for the squeezed vacuum due to the existence of the control light.
