Why the deadline he chose is so symbolic and the officer honored in the capitol he died protecting a powerful ceremony and the moment between the president and the fallen heros 7yearold Daughter Announcer this is nbc Nightly News with lester holt. Good evening, everyone the race to Vaccinate Americans against covid19 hit a gutcheck moment today, one concerning enough to cause federal health authorities to call for a pause in using shots made by Johnson Johnson. Thats because six women who have received the Singledose Shot later developed Blood Clots. One woman died the fda wants a pause now to investigate any potential links to the shots heres what we know. The cases are extremely rare 6 out of nearly 7 Million J J vaccinations given White House officials say they have ordered enough of the other two vaccines to keep up the current pace of Vaccinations Tonight more than 122 Million americans have received at least one dose of covid vaccines in a few minutes, my conversation with dr. Fauci about the news and what you should know. But first late details from miguel almaguer. Reporter after todays stunning announcement, states began canceling Johnson Johnson vaccination appointments the Fda And Cdc calling for a pause in the use of the Singledose Shot out of an abundance of caution authorities say six women out of the nearly 7 Million people who have received the vaccine developed rare and severe Blood Clotting one died another is in critical condition. Nbc news speaking exclusively to a 29yearold hospitalized in nashville. I went to the e. R. A week after the a week after the shot when i was having fever, and they didnt find anything strange in my Blood Work so went home and just continued to kind of worsen over the following week when i went back to the e. R. , its because my leg was so swollen that i couldnt really walk so at that time they found the dvts or the clots in my legs. Reporter doctors now believe an immune response likely led to the clotting some of the women had no preexisting conditions they were all between the ages of 18 to 48, experiencing symptoms like severe headaches, abdominal or leg pain, and shortness of breath within two weeks of vaccination the pause of J J shots dramatic but also likely temporary. Thats what the fda was signaling, saying even though these are rare, even though you could justify not pausing, they were going to take the extraordinary step just to offer that extra level of assurance. Reporter with authorities meeting tomorrow to figure out next steps, Johnson Johnson says in part, at present, no clear causal relationship has been established between these rare events and the Janssen Covid19 Vaccine authorities say for the millions already inoculated with Johnson Johnson, theres no reason to be overly concerned. For those scheduled to get it, theyll likely get Pfizer Or Moderna instead. And while the White House says the pause will not have a significant effect on the national vaccine rollout, the impact on Vaccine Hesitancy is unclear. I really hope people continue to get vaccinated. And that this doesnt cause more skepticism. Reporter tonight, pause for one Vaccine Maker as authorities hope the setback doesnt erode public confidence. Miguel almaguer, Nbc News dr. Anthony fauci is acknowledging this news has the potential to shake Vaccine Confidence but says transparency is important we spoke earlier this afternoon. Was a pause necessary in your view yes, i believe it was necessary for a couple of reasons. One, to investigate these a bit more to make sure we get much more of the details and the granular details of that but also its important during this period of pause to alert physicians on the outside who might see women or men, but mostly women as weve seen all six of these women, who might come in with a Clotting Disorder like this. Dr. Fauci, we were told these vaccines had been thoroughly tested, there were no shortcuts, that they were safe. If there is, in fact, a connection between Blood Clots and the J J vaccine, why wouldnt it have been discovered during the trials . Its a matter of numbers, lester for example, if you look in the clinical trial, generally clinical trials have anywhere from 30,000 to 40,000 people in it youre talking about an adverse event that has occurred in 6 people out of 6. 85 million people who were vaccinated in the united states with the J J. When you get out into the real world, youre giving it to tens and tens of millions of people, and it is at that point that you see if there is a rare adverse event. You will pick it up as you get into the millions of people who are vaccinated what would you recommend to anyone who has had the J J vaccine in the last couple of weeks . Is there anything they can do well, right now i would make sure they understand that this is really a very rare event. And, in fact, it had occurred in people in a very small bracket of time frame, between 6 and 13 days so if you have received a vaccine a couple of months ago, then i would think you would have absolutely nothing to worry about. I would be surprised if there was any issue there. If you had received it within a period of, lets say, two or three weeks or a week or two, i would tell them, a, again, its a very rare event. But you should be alert to see if you get symptoms of a severe headache or some issue with movement, strokelike syndromes, that that would bring you to the doctor make sure you tell them you have been vaccinated dr. Fauci says they have not seen this particular issue with either the Moderna Or Pfizer vaccines lets turn now to the tense situation in Minnesota Weve been following where the Police Officer who shot and killed 20yearold Daunte Wright following a Traffic Stop resigned today along with the chief of police. Ron allen is there Reporter Tonight the officer who fired the fatal shot and the Citys Police Chief both resigned amid growing outrage over the death of Daunte Wright.

Reporter Wrights Family demanding justice, rejecting the Police Statement calling the incident an accident, with the officer mistakenly using her firearm instead of a taser. I just shot him. Reporter police have not revealed the exact weapons the officer carried, but Law Enforcement experts say guns and tasers typically used look and feel very different. The Familys Attorney says there was no reason to use a Weapon Wright was stopped for an expired vehicle tag, and officers discovered he had an outstanding misdemeanor warrant. They could have given him a ticket but when its black people, they do the most excessive use of force. Reporter Chyna Whitaker and wright have a son together daunte is almost 2 she says he had a doting father. How do you feel about what happened im really just hurt for my son.

Reporter with the prosecution wrapping up, the defense took center stage, arguing that George Floyd died from drugs and preexisting health conditions, not Chauvins Knee on his neck. Put your hands on the dash. Reporter the first witness, a retired Minneapolis Officer who arrested floyd during a previous incident in 2019 as shown in this Body Camera video. The passenger was unresponsive and noncompliant to my commands. Reporter but under crossexamination, he acknowledged floyd eventually did comply a paramedic then testified floyd told her hed taken multiple opioid pills that day. I asked him why he said its because he was addicted. Reporter the defense then shifted to the night of Floyds Death in 2020. Speaking publicly For The First Time, shawanda hill, the woman in Floyds Suv, told the jury he was asleep when the officers approached the vehicle. I was like thats the police open the door, roll down the window, whatever they told him to do. So he looked back and when he seen the man, the man had the gun at the window when we looked back to him. So he instantly grabbed the wheel, and he was like, please, please, dont kill me. Dont shoot me. Reporter also taking the stand, a Minneapolis Park Police Officer who detained hill while other officers restrained Floyd The Defense played video from his Body Camera and he testified about the crowd of bystanders very aggressive aggressive towards the officers, yes. Reporter then the defense called its own use of force expert. I felt that Derek Chauvin was justified, was acting with objective reasonableness. Reporter the prosecution pushed back. In this moment, was this crowd a threatening crowd . No. The defense doesnt have to have a great case. The prosecution does because the prosecution needs a unanimous verdict to convict, but the defense only needs one stubborn juror to lead to a hung jury. Reporter outside the courthouse, floyds family stood shoulder to shoulder with the family of Daunte Wright. Police officers are killing us, and we are being murdered at a rate that i never thought i could imagine. Reporter it is not clear exactly how many witnesses the defense will call, but the judge has told the jury that he expects closing arguments on monday, lester.
