Fabienne Schlumpf

Swiss marathon record holder and Olympic athlete Fabienne Schlumpf has been diagnosed with myocarditis shortly after being vaccinated with the COVID-19 booster shot. Schlumpf, who finished 12th in the marathon race at the recent Olympic Games in Tokyo, is now unable to compete for the foreseeable future. The 31-year-old was reported to be feeling ‘fatigued‘ in everyday life and after her heart rate skyrocketed during an easy endurance run last month, she sought out a doctor who diagnosed her with myocarditis.
