Australian tennis player Alex de Minaur has insisted he is fully vaccinated following reports he was being investigated for buying a falsified Covid-19 pass.
The 23-year-old played in last month's Australian Open, where vaccination was compulsory.
"I want to make it 100% clear that I received my second shot," he said.
"I have a completely valid, accurate and true vaccination record."
Writing on Twitter, De Minaur added: "I received my first dose of the vaccine in London last summer and the second one at the Hospital La Paz in Madrid.
"News came out today that the hospital is under investigation for providing falsified Covid certificates to some of its patients.
