Sean Dyche's team have also drawn at third-placed Tottenham Hotspur and fifth-placed Liverpool and are currently seventh in the table after Saturday's 1-0 win at Southampton.
Vokes said Burnley have settled into the top flight.
"I don't know, I suppose it's the mentality," Vokes, who scored the winner at St. Mary's, said after the match.
"We go into games not fearing teams. It's three wins against top Premier League sides now and it's not just the wins, it's the performances that go with it.
"Last year, a lot was made of our away performances and our results have picked up. We are a proper Premier League team now and you feel that every day coming into work."
Burnley host 19th-placed Swansea City on Nov. 18 following the conclusion of the international break.
