After signing a new four-year contract, the Serbian has taken over from Patrice Evra as Sir Alex Ferguson's preferred choice as skipper in the continued absence of Rio Ferdinand and Gary Neville.
Vidic won his first silverware in the role last month when United beat Chelsea in the Community Shield at Wembley and on Saturday, the 29-year-old kept the job even though Ryan Giggs started the victory against West Ham at Old Trafford.
It is testament to the performances Vidic has produced since his £7million switch from Spartak Moscow four-and-a-half years ago.
And even though he is not taking the accolade that seriously, he is enjoying the experience.
"It is a big achievement for me," he said.
"No-one is going to say they don't want to be the captain of Manchester United and I am very happy with it.
"It is a major responsibility but I have always liked responsibility. I am not a player who shies away from it. Nothing has really changed in that respect."
Indeed, nothing has changed in the dressing room either.
Vidic's age and longevity does afford him veteran status alongside the likes of Jonny Evans, Nani and the Da Silva twins but Wayne Rooney has been at Old Trafford longer, while Darren Fletcher and John O'Shea are both Red Devils lifers.
All these players' contributions pale into insignificance alongside those of Giggs, Neville and Scholes, who are are approaching two decades service.
And, as Vidic acknowledges, even when they are not actually leading the team out of the Old Trafford tunnel, they are the true leaders.
"We all know the captains of the team are Gary Neville, Ryan Giggs, Paul Scholes and Rio Ferdinand," he said.
"They are the real leaders. The other players follow how they do things.
"They don't have to do anything special. They just have to be themselves to be an example for the rest of the players.
"When they are not on the pitch, I just try to do my best and use the experience I have gained in the years I have played for Manchester United."
