Former World No.1 Andy Murray says tennis players should have a COVID-19 vaccination in order to play in future tournaments.
The 2021 tennis calendar still remains uncertain with the Australian Open likely to be delayed with strict quarantine rules in place.
Murray said he would support a compulsory programme in the sport to ensure events went ahead.
“I think that probably should be the case,” he said.
“I would hope that all the players would be willing to do that for the good of the sport – providing everything has proved to be safe, clinical trials and everything have been done and there are not any significant side-effects.
“I’m confident that players would be into it if it meant the tour going back to normality.”
