“Novak applied for a medical exemption which was granted by a panel of experts,” said Tiley.

“Professional players do not have to reveal their personal or medical information… the grounds are the same for everyone.

“They were given the opportunity to be added to the Australian Immunisation Register which sees [some] people exempt from vaccines if approved by a panel.

“As an organization, we [Tennis Australia] abided by the conditions, and the decision was left in the hands of medical experts.”

Tiley confirmed that 26 players had applied for the same exemption with only a “handful” granted permission.
