Having stood up well to the pressure being put on them by the visitors, the Chemics edged back ahead prior to the interval when Patrick Ah Van used his full frame to cross over. Stefan Marsh then added to the scoring with two successful goals in the closing stages of the first half to put Widnes on their way.
It was to be St Helens who ran away with things in the second half, however, racking up four tries within 21 minutes of the restart through Atelea Vea, Luke Thompson, Jordan Turner and Hohaia to turn the contest on its head.
Burns was on target with each of the conversions to ensure that his side held control of the game heading into the closing stages.
An injury-hit Widnes showed some character as they battled away, and they were rewarded thanks to Aaron Heremaia's score late on which made the scoreline just that little bit more respectable.
