Vardy, 33, is the first Foxes player to reach the landmark in the competition and the first to score a century of top-flight goals since Arthur Lochhead in 1933/34.
Of the 29 players to have scored 100 Premier League goals, only Ian Wright, at 28 years and 286 days, made his debut in the competition at an older age than Vardy's 27 years and 232 days.
And at the age of 33 years, five months and 23 days, Vardy became the eighth-oldest man to reach the landmark.
|Player||Age for 100th goal|
|Peter Crouch||36y 0m 2d|
|Ryan Giggs||35y 11m 30d|
|Paul Scholes||35y 3m 18d|
|Teddy Sheringham||34y 6m 26d|
|Didier Drogba||33y 11m 28d|
|Ian Wright||33y 10m 10d|
|Dion Dublin||33y 7m 1d|
|Jamie Vardy||33y 5m 23d|
"It's an incredible achievement," Rodgers told LCFC TV. "I've said earlier that to come into the Premier League at that age and now to get over 100 goals, it's a remarkable performance level. There's many more to come from him."
His brace also sent Vardy two goals clear in the race for the Golden Boot, in association with Cadbury.
Vardy now has 21 goals this season, two ahead of Pierre-Emerick Aubameyang.
He is three goals shy of his best Premier League season of 24 goals, which he record in Leicester's title-winning season of 2015/16.
