The 2015 season had started well with a win in the 60 m at the 2015 European Athletics Indoor Championships in Prague, (Czech Republic). At the 2015 World Championships in Beijing Schippers won the silver medal in the 100 m and gold in the 200 m, just before Elaine Thompson. Her 200 m winning time of 21.63 seconds was a new European record and made her the third fastest woman in history over that distance. The Dutch 4 × 100 meters relay team (Nadine Visser, Schippers, Naomi Sedney and Samuel) finished fifth in 42.32, but was disqualified for a changeover infringement. In the heats the team had also run 42.32, a new national record. Her stunning victory opened her up to scrutiny about possible doping. There were questions about the acne on Schippers back and face, which can be a sign of steroid abuse. Most insiders, however, dismissed those claims, pointing out that the acne was hereditary in the family and the fast track in Beijing.
