Tennis' world No 1 Novak Djokovic reportedly holds an 80% stake in a biotech company aiming to develop a treatment for Covid, which does not involve vaccination.
Djokovic has long been opposed to the Covid vaccine, and now appears invested in finding a way he can protect himself and others who are opposed to having their jab.
Reuters have reported the Serb - who was recently deported from Australia after having his visa revoked twice having initially been granted a medical exemption - has joined forces with Danish biotech firm QuantBioRes.
