ah, 3 years that would change the world forever. but jillions journey around the world, september 7th on d w. ah ah. ah, this is dw news live from berlin, a mission to prevent catastrophe. a team of you and experts is making its way to the russian occupied zapper region, nuclear power plant in ukraine to safeguard it from the fighting, raging around the site. also coming up on the shaft world leaders paid tribute to

mikhail gorbachev, the last leader of the soviet union and the man credited with helping to end the cold war. last, the u. s. approved updated cove at 19 vaccine that target the latest strains of the omar prawn variance, the new booster shots could be going into arms in a matter of days. ah. hello, i am clare richardson, thanks so much for joining us. inspectors from the u. when's nuclear watchdog are on their way to europe's biggest nuclear plant in russian occupied ukraine? the long awaited mission to the sapir asia plant is aimed at safeguarding the site against catastrophe. fighting has raged for weeks in the area around the complex aah! arriving to conduct what the head of mission calls a very complex task un inspectors are preparing to visit bizarre parisha power

plant on thursday. for now, the team remains in ukrainian controlled territory. but the head of the un mission was clear that they are heading to a wall zone, insisting his team house one job to prevent a nuclear accident. you know, we don't carry dimension. thickness. is a mission that seeks to prevent a nuclear accident and to preserve, as it's important, the largest, the biggest threat, bowers and in europe, the whole of europe, not only in ukraine. so this is what we are concentrating. ukraine and russia had accused each other of shelling areas near to the facility last week. damage to a transmission line, not the plant off line heightening fears of a radiation leak, or even a react to meltdown. ukraine's energy minister said the visit by the un should

drive home the dangers posed by zakiria. the most important that this wizard should, ah, underlying the importance of nuclear security and that the russians should understand that they cannot play with this any game. as combat continues on ukraine's eastern front, all eyes runs up her regia hoping to prevent a disaster, but could reach far beyond the country's borders. did other correspond at martinez? belinda is in the city as operation and he told us what he's learned about the un nuclear inspectors chances of crossing into russia. how territory we are urine conflicting signals. russian officials have announced that they will arrive to morrow morning, indicating that it will be a speedy process either. on the other hand,

the occupational authorities have said that they will not be handed a pass through the checkpoints and then they will, they will have to queue up like everybody else, potentially delaying their arrival. it will be very important for them to reach the site and to figure out what's really happening. they are shelling a has occurred today again on reserve. we really don't know how safe the situation is at the moment, but the original plan is that they will travel there to morrow and then they will get access to the plant. of course, on it much as long as speaking to us earlier on tributes are being paid to mikhail gorbachev who has died at the age of 91. the last leader of the soviet union, he helped ends the cold war by forging warmer ties. with the west. germany's chancellor, olaf schultz said gorbachev had been a courageous reformer who dared to do many things. russian president vladimir putin hailed him as an extraordinary global statesman. but the kremlin said gorbachev had

been badly wrong about the prospect of rapprochement with what it called the bloodthirsty west. so let's take a look at me. i'll gorbachev's legacy as seen through the eyes of his fellow russians. sama blame him for the soviet union's collapse. and even see him as a traitor. russia's news channels reported that president blood, amir putin had expressed his deepest condolences. but musk invites themselves were not united in mourning their former leader. one waiter was guys a will he laid the foundation fraud, democracy that existed in the late ninety's and early 2 thousands was much more. he was a remarkable politician. the only and last president of our country who did good and bad things of that as well. you'll see that the country fall apart, and now my relatives live in a different country that the ex soviet republics aren't together anymore. that's bad. ocean blue for a little. we lost our home country and are restoring it. now. it was a big one. now it's a small one. wiling. in gorbachev's,

homeland ambivalence reigns, kremlin spokesman dmitri pasco, of hailed him as a statesman who will go down in history, but dismissed his hopes, of a rapprochement between russia and the west. as romanticism that did not work out was in the face of what he called the bloodthirsty innes of moscow's opponents. and in the united states, health officials have approved updates to coven 19 vaccines that target the latest strains of the oma kron variance, the tweak to booster shots made by materna and pfizer, by on tech could be available in a matter of days. they will only be administered to people who have already received their primary vaccinations. so let's get more on why covered vaccines needed an update and how it's been done. to help fight off coven 19 vaccines induced defensive measures in the body. among them are the production of protective antibodies that can recognize and latch on to the surface of the corona

virus. especially it's spike protein that can stop the virus from docking on to cells to infect them and flag it up for destruction by other immune system defenders. but if the structure of the spike protein changes due to mutation, it can have consequences. the immune system might no longer quickly recognize the invader. ami cron has over time adapted to become all the more efficient for infecting human cells. there are a number of parameters and characteristics that make it a really difficult virus to deal with. one of which is because it has changed some of its surface structure by a mutation. and the spike has a number of changes m r n. a vaccines use snippets of genetic code to make the body produced to spike protein to stimulate an immune response to sars covey. to re

writing the code is a pretty fast and straightforward process, and changing it changes the vaccines associated spike protein. so why have amazon specific vaccines taken so long to arrive? this has a lot to do with 2 factors. factor one, we're not sure that better adapting and refining the vaccine is genuinely going to afford a market improvements in protecting against future infections. and then of course, at the level of the manufacturer, decisions has to be made. when do we bite the bullet and actually now produce a new vaccine. experts hope messenger r n a vaccine technology will help us keep pace with new variance of sars covey to as the virus continues to evolve. ever more on this,

let's bring in it. william schaffner, a professor of preventative medicine at vanderbilt university in nashville, tennessee. great to see you again. we are clearly playing catch up as this virus continues to mutate. how much additional protection do you think this new booster will provides? well, we certainly hope that this new booster will provide substantial additional protection against serious disease disease, serious enough to require hospitalization. we also hope it provides some, but we know it won't be complete protection against infection. those mild infections will continue. but if we keep people out of the hospital, we will have achieved our goal. now, these updated boosters aiming to provide cross protection against several variance are only for people who have already had the original vaccine shots. why is that? well, that's correct. at the moment,

these new vaccines have not been tested as original vaccines. they're only there as an updated booster. and so you have to get vaccinated with the original vaccine before you qualify for one of these updated vaccines. ok, so you need to do the full course and then get this new booster vaccine with covert here to stay. do you think that these boosters are going to become a yearly thing? akins, the flu shot. that's everyone's favorite question. we don't know the answer to that yet and hasn't been decided, but i will say it is likely so as with influenza where we create a new vaccine each year and get vaccinated. so to i think with co good will be doing something similar going into the future. because coven itself, the virus, is not going to disappear. and what about the prospect of even having a 2 in one that covers both flu and cov 19?

0, that's wonderful. not this year, we won't have a combined influenza and cope with vaccine, but scientists are already working on that for next year. okay. now in the united states though, we know that many people are still skeptical about rolling up their sleeves. just half of vaccinated americans got their 1st booster dose. according to the cdc, i'm do you think that we're going to see that number dropping further for this one? i think we will have to sell this car as it were. we are going to have to really promote this vaccine because there's a lot of vaccine the t. and in addition, this fall, we will be asking people to roll up both their sleeves. once high for influenza, the other side, for cove, it. that will not be universally well received. so we're really going to have to be very persuasive. william schaffner, professor of preventative medicine at vanderbilt. and i thank you so much for

taking the time to speak with us on date of the unit. my pleasure. while the world's oldest film festival, the venice film festival has kicked off after taking place under covert restrictions for the past 2 years. it is the 1st time the event is happening without masks since 2019. with an all star lineup of celebrities and films. it's also hoping to make a return to the glitz and glamour of festivals past. ah, then when it comes to old world movie magic, no one does it better than the venice film festival. for this year, the goal is clear to get film fans excited about going back to the movies in female figures or, and focus on the lido cuban actress on a day a mos plays marilyn monroe and blog showing the darker side of the hollywood icon.
