Former world No. 25 Jeremy Chardy says he has a "series of problems" after taking the COVID-19 vaccine and his 2021 season is over. This summer, 34-year-old Chardy decided to get vaccinated and it didn't work out well for him.

Chardy, now ranked at No. 73 in the world, claims he is unable to train and play. "Since I got my vaccine [between the Olympics and the US Open], I have a problem, I have a series of problems. As a result, I can't train, I can't play.

[...] I prefer to take more time to heal myself and be sure that, in the future, I won't have any problems," Chardy told L'Equipe.

Chardy regrets taking the vaccine

"At the moment, my season is stopped and I don't know when I'll start again.

[...] So now I regret having taken the vaccine, but I couldn't have known. [...] It's the first time that the idea that next season might be my last has crossed my mind," Chardy added. Last month, world No. 3 Stefanos Tsitsipas expressed reluctance about taking the vaccine.

"The COVID-19 vaccine has not been tested enough because it is new and has some side effects. I know some people who've had them. I'm not against it, I just see no reason for someone in my age group to be vaccinated [yet]," Tsitsipas said in August.

"For us young people I think it's good to pass the virus because we'll build immunity. I don't see it as something bad. As I said, it isn't obligatory, everyone has freedom to decide for themselves what's right & what's not.

"At some point we should all do it, I'm not saying the opposite. The time will come when we will not be given many options, but until then I want to see a better version of the vaccine that gives us more pluses than minuses."

However, Tsitsipas changed his views as a couple of days ago he revealed he's planning to take the vaccine before the season ends.
