Novak Djokovic is against any compulsory vaccinations for tennis players returning to the game after the coronavirus hiatus, and faces a dilemma if forced to do so himself.
"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.
"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."
