Tennis star Novak Djokovic's comments about Covid-19 vaccination will "cause harm", a medical expert has claimed.
His views are "enormously influential" and could "reinforce beliefs" among people who are not as fit and healthy, according to Professor Dominic Wilkinson, professor of medical ethics at the University of Oxford.
Meanwhile Health Secretary Sajid Javid suggested that the only reason Djokovic was able to return to playing tennis "and earn millions again" was because of the success of the Covid-19 vaccination programmes.
