Novak Djokovic has been granted permission to play in the Australian Open. All players and staff at the tournament must be vaccinated or have an exemption. Djokovic has not spoken about his vaccination status, but last year said he was "opposed to vaccination" Australian Prime Minister Scott Morrison said there should be no special rules. The controversy comes as the country is seeing tens of thousands of Covid-19 cases. Over 90% of Australia's over-16 population is fully vaccinated, but some Australians still cannot travel interstate or globally because of restrictions. A&E doctor Stephen Parnis tweeted: "I don't care how good a tennis player he is. If he's refusing to get vaccinated, he shouldn't be allowed in"
