Hosts Huddersfield twice went in front, but were pegged back on both occasions - including a goal five minutes from time.
However, rather than be downbeat, striker Vaughan has insisted that "every point counts".
"Felt like two points dropped today, however, at this stage every point counts! Go again next week and hopefully get the three points," he wrote on Twitter.
The result has left Huddersfield 21st in the Championship standings, just one point above the drop zone.
