Vibration. the  oscillating,   reciprocating,  or  other   periodic   motion  of a  rigid  or  elastic   body  or  medium   forced   from  a  position  or  state  of  equilibrium.

Shockwave: a region  of  abrupt   change  of  pressure   and   density   moving  as a  wave   front  at or  above   the   velocity  of  sound,   caused  by an  intense   explosion  or  supersonic   flow   over  a  body.

So basically, vibration relies on oscillations while shockwaves rely on change and pressure, and involve the speed of sound. I hope this is good enough of an explanation.
