and the tracing of the sources in order to stamp out the local outbreaks, and we all know this is so far the worst outbreak since wuhan. just briefly, dr chen, do we know much about vaccine rollouts in the areas affected and how this virus is going to fare with that? yeah, in general, china has a very high vaccination rate. it s slowing down but it s still very high and in some areas around like 80% of people have been vaccinated. it varies a little bit. but given this is delta variant, so the threshold of immunity will be changing, so even by the end of this year, the chinese authorities are aiming for about 70% 80% of people vaccinated. so far, just ten days ago, they reached 1.4 billion doses
being vaccinated, so but given the new delta variant, it will take an even higher number and proportion of people to be vaccinated to fight against this delta variant. doctor xi chen. president erdogan of turkey says fire fighting planes from russia, ukraine and azerbaijan are now battling the wildfires on the country s southern coast. four people have died and dozens have been taken to hospital. the flames have forced the evacuation of entire villages. david campanale has the latest. soaring flames have turned summer skies blood orange over turkey s luxury hotels and villages. dozens of neighbourhoods and tourist resorts had to evacuate before the onslaught of the wildfires, which have stretched along the mediterranean and aegean coasts. we don t know anything. the personnel at our hotel

situations. and so far, most of the cases already have been traced the origin of the virus outbreak, which is good. that means it is still in the early stages. but there are still a few cases in some provinces and some sources are unknown so it is not clearly linked to nanjing so this is worrisome, so they have to be there quick on contact tracing and the tracing of the sources in order to stamp out the local outbreaks, and we all know this is so far the worst outbreak since wuhan. just briefly, dr chen, do we know much about vaccine rollouts in the areas affected and how this virus is going to fare with that? yeah, in general, china has a very vaccination rate. it s slowing down but it s still very high and in some areas around 80% of people being vaccinated. it varies a little bit.
