At the 2008 U.S. Olympic Trials, Vessey finished 5th in the 800 m, with a time of 2:02.01. In June 2009, Vessey was a surprise winner at the Prefontaine Classic, in 2:00.18. The race director said Vessey "was a last-minute, last-minute add. One step above a field-filler". The competition included Olympic gold medalist Pamela Jelimo.
Vessey continued her impressive results in 2009. At the Herculis meet in Monaco, she won the race with a time of 1:57.84. At the time, this was the fastest 800 m performance for the year, and tied for the seventh fastest by an American runner. This result earned Vessey a place on the US 2009 World Championship team—she finished 4th at the 2009 U.S. Championships, and needed to break 2:00 to earn an "A" standard.
At the 2009 World Championships, Vessey finished seventh in the 800 m semifinal with a time of 2:03.55. At the 2009 IAAF World Athletics Final in Greece, Vessey took 2nd and the Silver in a time of 2:00.31.
In 2011, masters runner Rose Monday became Vessey's coach. She qualified for the finals of the 800 m at the 2011 World Championships in Athletics, where she finished sixth, even moving up to fifth place later because of the disqualification of Russian Yekaterina Kostetskaya. A week later, Vessey won the 800 m in 1:58.64 at the Hanžeković Memorial as part of the IAAF World Challenge Meetings.
At the 2012 US Olympic trials, Vessey finished eighth in 2:03.44.

Benoit Duboscq serves as her strength coach. In May 2015 Vessey ran the second leg of the 4x800m US National Team which won the gold medal at the IAAF World Championships in the Bahamas and set a pending USA national record. It was the world's fastest time in this event for more than 20 years. Her split was 2:00.92. She also has individual 800m victories in 2015 at the Palo Alto Stanford Invitational, the Hoka One One Occidental Invite, and the Prefontaine Classic National 800m. Maggie tripped on someone's leg in the 800 meters final with 250 meters to go and  finished 8th at 2015 USA Outdoor Track and Field Championships. She finished 7th in 800 m prelims 2016 United States Olympic Trials (track and field).
