Unvaccinated Novak Djokovic made headlines at the Australian Open in January after first receiving a medical exemption to play, but then being deported by the government following a legal battle.
"Personally I'm opposed to vaccination and I wouldn't want to be forced by someone to take a vaccine in order to be able to travel," Djokovic insisted.
"I know some people that, through energetic transformation, through the power of prayer, through the power of gratitude, they managed to turn the most toxic food, or maybe most polluted water into the most healing water.
"Scientists have proven that in (an) experiment, that molecules in the water react to our emotions to what has been said."

The Serbian tennis superstar currently sits joint second with Roger Federer behind Rafael Nadal in the all-time Grand Slam victory table, needing just one more, a 21st title, to draw level.
However, in a BBC interview, Djokovic stated he was not willing to become the most decorated Grand Slam winner in the history of the sport, if it meant not sticking to his principles of free choice and not having the life-saving Covid vaccine.
Will Djokovic play in the French Open?
Djokovic won last year's French Open, coming back from two sets down to beat Stefanos Tsitsipas at Roland-Garros, but doubts surrounded his eligibility to take part in the 2022 edition on clay.
The 2022 French Open will officially get underway after qualifying on May 22 and as it stands, the Serb will be able to defend his crown.
Despite previously requiring every entrant into the country to be vaccinated, recent changes mean Djokovic can not only enter France, but compete.
"As things stand, nothing stands in the way of Djokovic taking part in the French Open," tournament director Amelie Mauresmo said in March.
Djokovic has a great chance of equalling the Grand Slam record this year, with Federer out. The 40-year-old is continuing his rehabilitation after knee surgery last August, while Nadal arrives in Paris with doubts surrounding his fitness.
