Simona Halep has become one of the first active players, at least publicly, to get the COVID-19 vaccine. The 29-year-old received her first dose this week in Romania. 

One of the ways the world No. 3 would have been eligible for the vaccine is due to her status as an Olympic athlete. While it's become a highly political issue, it's up to each nation to decide if and when to vaccinate its athletes ahead of the Olympic Games in Tokyo, which start on July 23. Olympic organizers have said they will not require athletes to be vaccinated to participate. 

Halep contracted COVID-19 last fall after skipping the New York swing and losing in the fourth round of Roland Garros. She just reached the quarterfinals of the Australian Open, falling to Serena Williams, and has withdrawn from next week's WTA 500 in Doha. 

Per guidelines, she'd need to get her second dose during the week of March 15, meaning she could still play Dubai before and then head to Miami afterward.
