theit has fuelled the vaccination debate in serbia, where less than half of the country's population are fully vaccinated. so where does all this leaves the serbian government's vaccination campaign? from belgrade, our balkans correspondent guy de launey reports. this time last year serbia was leading the european race to vaccinate its people against coronavirus. while other countries were struggling for supplies, serbians could choose from four different covid jabs, but now the campaign's gone from plain sailing to being stuck in the doldrums. translation: we would vaccinate 5,000 or 6,000 people a day - at the belgrade fair. then it dropped to 2,000 during the summer, and in recent weeks the number has fallen drastically to 300 doses per day. all that means that only around half of serbians are fullyjabbed, and that's why the vaccine hesitant stance of novak djokovic isn't as controversial here as it is in australia. still, serbians who are getting jabbed are hoping the sporting icon will come round to their way of thinking. translation: when there - was a davis cup game in serbia he was bringing tennis players for vaccination here, so i believe some day he will get that vaccine. translation: what's going l on in the background is politics more than anything else.
