Novak Djokovic says his opposition to vaccinations may get in the way of his return to competitive tennis.
“Personally I am opposed to vaccination and I wouldn’t want to be forced by someone to take a vaccine in order to be able to travel,” the world No 1 said in a live Facebook chat with several fellow Serbian athletes on Sunday. “But if it becomes compulsory, what will happen? I will have to make a decision.
“I have my own thoughts about the matter and whether those thoughts will change at some point, I don’t know.
“Hypothetically, if the season was to resume in July, August or September, though unlikely,
I understand that a vaccine will become a requirement straight after we are out of strict quarantine and there is no vaccine yet.”
