Hit by flooding in sudan. One of the worlds most advanced vaccine trials has been put on hold off to a participant fell ill astra zeneca says a patient has a potentially unexplained illness which will need further investigation the pharmaceutical giant is working with Oxford University to develop the vaccine late stage testing got underway last week thousands of taking part in the u. K. U. S. Brazil and south africa its hoped 3000000000 doses can be distributed globally but julie fisher is from Georgetown Medical university she explained why these steps have been taken. At this point a group of external experts will be consulted and its a normal part of the process theyll be called in to see if any adverse events that were reported and were serious are likely to be due to the vaccine or to be unrelated and their advice will help decide whether or not the vaccine trial continues we are all familiar with my old verse of events that can happen after vaccination like fever or pain at the side of the injection to put a pause it has to the the event would be serious something that was perhaps related to. The heart the lungs the kid is another system in the body. That was really required medical attention and that was found to be serious enough to merit causing this very important effort to test this vaccine in order to make sure that the vaccine is safe and that the adverse events were not due to the vaccine itself there is a set of expectations to test the safety of any vaccine that will be given to 2 people and that that is that would be tested in a small group of volunteers to make sure that it is safe and has a reasonable chance of being effective before even going into larger groups of volunteers much less the public without that kind of testing we just dont know for sure if the vaccine will protect people from an action i think we would like to see one as quickly as possible all of us but i think its reasonable to assume that it would be at the very earliest the end of 2020 and more likely 2021. Well astra zeneca is one of 9 Drug Companies that have pledged not to rush approval for vaccines until proved to be safe the joint statement from the companys c. E. O. s comes as President Trump continues to suggest that a vaccine could be out as early as november that would be right before election day White House CorrespondentKelly Holcomb explains how the development of a punk scene is being politicized this is unprecedented according to some drug Industry Experts what i can tell you is that the u. S. President has certainly been touting that the vaccine may be released by the end of the year then as recently as yesterday on the steps behind me at a press conference he said even by the end of october of course the timing rather interesting given that election day is november 3rd and that seemed to cause some alarm among the c. E. O. s of these major Drug Companies because quite unexpectedly and again without precedent they released this letter stating that they are only going to release a vaccine when it is safe to do so and they wont sort of rush for any arbitrary timeline put forward by a politician now in the case of donald trump he certainly is pushing to get this is quickly as possible looking for a success given the fact that he is lagging in the polls but he is not the only one politicizing it in fact his rival joe biden is hammering hard on Donald Trumps sort of claims that hes handled the krona virus very well in fact the focus of a new ad being put out by the Biden Campaign is that hes framing the contrast between himself and donald trump darkness versus a fresh start as he calls it. The largest migrant and refugee camp in greece has been partly vacuum waited because of several fires strong winds fanned the flames at the maria camp on the island of les vause reports say some of the fires were started deliberately to protest newly imposed coronavirus restrictions the facility was placed on a current in the last week after the 1st case was found infections have since risen to 35. 00 but Douglas Herman is the cofounder of refocused media labs thats a thats a group that works with citizen journalists inside moria camp he says the increase restrictions led to riots and the fires being started. At the current moment there are several fires that are kind of all over the camp. Yes corona has been identified in this camp in recent days and the number of confirmed cases have been rising many of the asymptomatic people have been put into a quarantine area on the far eastern side of the camp and that area earlier this evening was attacked by individuals who seemingly do not believe that corona is actually in the camp and that it is being seen as a reason to continue a 6 month lockdown in the camp some attacks on some vehicles to move people out of the camp or to move them around ensued and some of the people that were in this corner an area were fleeing from that violence and in the process of that several fires were set on the perimeter and then now those fires have been set inside the camp also office for the asylum seeking process takes place is on fire our students living quarters are on fire. Numerous people have been evacuated from the area of their own accord or are now by authorities the space that was created for quarantine was for anyone who had recently tested or had been potentially connected to anyone who had tested positive of those cases where its symptomatic and they were just basically quarantining them off to the side for 14 days so once you know once night falls its kind of not necessarily you know aggressively policed and in this area some individuals gathered and started arresting some of the people that were inside and some sort of violence ensued the images and the photos and the stories that are coming back from our students are that you know this violence has just kind of turned into kind of a full scale riot. Please police chief and other Senior Officers in new york States Rochester city have announced theyre stepping down as criticism grows over the departments handling of daniel prudes arrest and subsequent death protests erupted after details emerged about the incident which took place in march a black mans family released previously unseen video which showed police putting a hood over his head as he knelt naked and restrained on the street he died a week later he was taken off life support 7 officers involved have been suspended a grand jury will help determine whether charges should be brought smoking or not hope mariotti in chicago hes a former u. S. Federal prosecutor or not oh so the Top Police Chiefs in rochester have now stepped down how significant is this and how much pressure was on them to quit do you think well i think there is significant pressure 1st of all theyre obviously being heavily criticized for their actions theyre also being asked to reform a Police Department which is not an easy thing to do theres a lot of forces working against that and their own activities are under scrutiny and we dont really know whether or not for example some of the folks that are in that Community Church are also under investigation yeah thats an interesting point you make the analogy because the proved case happened back in march and the rochester men recently expressed frustration that the police chief didnt inform how soon a about the case do you think there was an attempt by the Police Leadership perhaps to cover up the details of the case. Well if thats possible and if it was the case there may be a criminal Investigation Underway of some of those members of the hierarchy and that would certainly give them a reason to step down because a disciplinary action could be taken against them that would require them to testify something that would protect would potentially hurt them in a criminal proceeding or not so we know that 7 Police Officers have now been suspended over the death of Daniel Pruden and this grand jury will determine with the charges should be brought against them so just talk us briefly through what other legal challenges involved in getting a conviction against these offices given that the autopsy report for example found the prude was high on p. C. P. Well 1st of all its always difficult to obtain a conviction against Police Officers i just know from experience that they do you know jurors and grand jurors even in the indictment stage give the benefit of the doubt to officers so theres that working against them and then of course its difficult to prove the an officer state of mind and officers can always say that they you know werent sure they they saw something or observed something that isnt captured on the video they can create reasonable doubt in the United States you have to prove their guilt beyond a reasonable doubt and includes proving their intent just a final thought to you right now to we we saw of a down the old prude family released that controversial body count footage of the arrest in the hood being placed over his head how crucial will that video be in a court of nor do you think oh absolutely critical in fact if it were not for that video i dont think you are and i would be discussing this case that video is what makes this entire matter so vivid that is hard to deny that there is something very wrong that happened to mr pruitt went on to mariotti thank you very much indeed for your time thank you thank you.
