Returning to normalcy. The fbi Say Pipe Bobs found near the capitol before the riot. The monster winter storm sweeping coast to coast and the Deep Freeze Gripping the northeast. A video of a School Officer body slamming the student, the family is speaking out. Paying tribute to the hollywood icon this is nbcs nightly news with lester holt good evening everyone, we begin with major developments with the fight to control the pandemic Johnson Johnson announced just ready to speak fda approval for its single shot vaccine of their critical phase 3 trial the j j vaccine is not quite effective than the other vaccines already in the market that variant just discovered in the United States adding further urgency to lagging vaccination efforts. I spoke to dr. Fauci a short time ago trying to get some clarity in all this. He had an interesting answer whether people can be reinfected from emerging variant of the virus. My interview is coming up in just a moment. Lets start with tom costello. Reporter pandemic experts say the data today from Johnson Johnson suggests doctors may have another effective tool to fight covid take a look at the numbers j j says its vaccine is 72 effective at preventing covid in the u. S. 85 effective and preventing the most serious symptoms, that compares to the pfizer and Moderna Vaccines are 95 effective. Importantly the company says it was less effective against the dangerous South African strain no one received the j j vaccine went to the hospital or die of covid. We have 100 efficacy against going to the hospital, 100 efficacy against death this is a big result reporter the j j vaccine has two big advantages it requires one shot and not two like the others. It does not need to be kept at ultra cold temperatures, making it easier to ship and distribute it would be a mistake to compare j js 72 Efficacy Rate with a 95 Efficacy Rate to me, one shot is better than two because i hate needles and shots. Reporter some americans may choose the pfizer or Moderna Vaccine over j j i dont mind having to come back for a second dose if it is going to be a little more effective. Reporter americans are told in advance which vaccines they are receiving. Some americans are reluctant to get this vaccine. Take what you can get and especially when you have a vaccine thats disinfected, we are lucky to have this reporter one more important stat, while the j j vaccine is 72 in the u. S. , the flu vaccine is just 45 or 60 effective whats the Timeline Reporter yeah, they could get Emergency Authorization within weeks the government already has a 1. 5 billion with j j for 100 million doses by the end of june, lester tom, thank you very much. Todays development, i spoke a short time ago with dr. Anthony fauci to get some perspective. I started off asking him if the new vaccine news was positive or disappointment this is actually good news. It is valued and the whole effort of getting more Vaccine Candidates into the mix. You know we have two successful vaccines that have Emergency Use authorizations the mrna from pfizer and moderna. This is another type of the vaccine. It is called a viral vector vaccine. Even though the results show a 72 in the United States, it was a study that involved not only the United States but also south africa and brazil. The important point is that the protection against severe disease was very high even in south africa where the mutant is dominant even the numbers when you compare against mild to moderate disease, 72 verses 94 or 95 , clearly 94 and 95 is better but from a practical standpoint from what you want to do to keep people out of the hospital and prevent deaths, this is value added. Number one, it is a single dose and much more convenient it does not require a stringent cold chain you can keep it refrigerated it is relatively cheap and the company can make billions of doses so it will have value. That leads to my next question, when you say effectiveness, is the goal to keep us healthy completely healthy uninfected or keep us alive . It is both. The most important thing that challenged us as you well know is what we have gone through with this extraordinary historic pandemic, we have about 430,000 deaths so one of the important things you want to do is to keep people out of the hospital. If you could also protect them against any kind of symptoms that would be good when you look at early disease, the Johnson Johnson, is 72 effective. If you look down the pike at keeping people out of the hospitals and keeping them alive, thats where the value is at it. Not quite as good against the early disease but against the serious consequences, it has done very well what do you say to folks who say i want the best, the most effective vaccine and this one just does not offer enough of it well, you know, first of all, people would want to get the choice of what they want there will be a messaging issue exactly for the reasons that we are discussing right now when you compare that initial number of 72 verses 94 to 95 , there very well may be people who actually prefer to have one dose, they would say the difference in efficacy against early disease does not make that much difference. So, i think there will be usefulness of it there will be some that say numerically is the best efficacy, thatll happen and thats the messaging issue let me ask you about the South African variant, we have seen a couple of cases in South Carolina would you say it is localize and is not a big deal . It may be wishful thinking. We would hope that we could get our people vaccinated as quickly as psible befo anything spreads the way it is spread in south africa where it is clearly a dominant strain. When ever you see a couple of cases, you could be sure that you will see a lot more. It is not going to stop at a couple of cases. Thats the nature of how that viruses spread as you see more variants, does that raise the risk of reinfection. People already have covid and potentially facing it again. Thats an excellent question and thats what is seen in south africa when we were communicating with our many scientific and colleagues in south africa they would tell us something strange is going on right now. We have people infected several months ago and now with the new strain getting infected. The immune response induce to the first infection was not good enough to prevent the second infection. However, it appears that the vaccine itself appears to be better of inducing that kind of protection because they had anywhere from 50 to 88 severe disease. Vaccination appears to be good or better natural infection than preventing further infection does this push back the calendar in terms of when life may appear to be normal again. Is this putting pressure on your projection of that point possibly but not necessarily. I believe if we Pay Attention to these mutants and adapt the vaccines to upgrade them to do that that we still would be able to get to some form of normality as we get to the mid to late fall as i predicted a few months ago. It is going to require a good and efficient way of vaccinating as many people as possible and our thanks to dr. Fauci for joining us he tells me hes growing more optimistic efforts to ramp up vaccinations rising concerns of those variants as more americans defy safety guidelines. Here is miguel almaguer. Reporter labs like these across the nation, scientists are racing to discover more dangerous variants of the virus. The cdc is working with all 50 states to ramp up surveillance universities and hospitals are at the forefront detecting the Virus Mutations thats resilient to the vaccine we are worried of the South African variant because it appears to make the vaccine less effective. Reporter now the South African variant discovered in South Carolina it is Community Spread a greater number of americans are currently infected spreading the variant and dont even know it we should be treating every case as if it is a variant during this pandemic right now reporter it is possible though not certain some variants may make you sicker or deadlier. Many do appear to be more contagious reporter the u. K. Variant is already becoming more prevalent in the u. S. , nbcs Janis Mackey Frayer is in china it is perhaps the perfect storm to fuel new variants and a deepening crisis miguel almaguer, nbc news. Up next now the manhunt intensifying the person who placed two pipe bombs near the u. S. Capitol discovered the day of the siege here is pete williams. Reporter the fbi says the bombs were planted the night before the capitol siege between 7 30 to 8 30 p. M these videos obtained by the fbi and the washington post.
