While scientists work to come up with a safe and effective COVID-19 vaccine, doctors across the country are watching closely. Many are helping guide their patients in making an informed decision about getting a vaccine."This was indeed a surprise to see that there would vaccines available by the 1st of November. It’s clearly an aspirational goal, because we all would like to see a safe and effective COVID-19 vaccine as soon as possible, but I think testing vaccines to make sure they’re safe and effective is of paramount importance," said Dr. Bali Pulendran, a microbiology and immunology professor at Stanford University.Dr. Pulendran says the process of developing a vaccine involves numerous steps, and scientists are getting closer to the end. Still, it's hard to put an end date on the third and final phase of a vaccine trial. This last phase determines whether the vaccine actually works."The way in which you can assess whether a vaccine works is to see how many of these people acquire the disease or become infected with COVID at some period of time," explained Dr. Pulendran.Phase three divides the trial participants into two groups. One group is given the vaccine, and the other is given a placebo."And then, you calculate the efficacy based on those numbers. So, if there were 200 people affected in the placebo group but there were only 100 people who were infected in the vaccinated group, then the efficacy is 50 percent" said Dr. Pulendran.The third phase is hard to time, as it depends on how quickly some of the trial participants become infected. If they live in areas where COVID-19 infection rates are higher, the phase will be completed faster.But there are some other ways to speed up the vaccine trial.Dr. Darria Long, an emergency room physician and clinical assistant professor at the University of Tennessee-Erlanger, says one way is by doing two of the phases at the same time. Another way is if officials prepare for the manufacturing and logistics side of producing the vaccine during the third phase of the trial."This is what we see the CDC saying is to get ready on the manufacturing and logistics side because even if you come up with the perfect target drug, making sure you can manufacture hundreds of millions and that you have the little glass vials that can keep it at the right temperature, those are all things that can be hang-ups,” said Dr. Long. “So, they're wanting to expedite that process, because the last thing you want is to say is we have the vaccine, but we can’t get it to people.”Dr. Long is already answering her patients' questions as news of a possible COVID-19 vaccine continues to be publicized."I do think a lot of people are wondering about this vaccine and it runs the gamut. There are those that say they really want the vaccine because they see it as this gateway to getting back to life as we know it," said Dr. Long.There are also those who are really concerned about the efficacy and safety of a COVID-19 vaccine. Doctors say a key piece in evaluating a vaccine when it does come out is the data surrounding it."The data that comes out in the public domain: is a particular vaccine efficacious? How effective is it what is the efficacy data? Is a particular vaccine safe? What are the side reactions? And they should talk with their physicians to ask each question. Ask doctors, ‘Could you tell me what the safety part of this vaccine is?" recommended Dr. Pulendran.And above all, doctors and scientists hope politics will stay out of the development of a COVID-19 vaccine in order to ease any concerns or hopes for a vaccine to be available as soon as possible. 3644

While we’re still waiting on a comprehensive COVID-19 vaccine distribution plan, the Johns Hopkins Center for Health Security released an ethics framework Wednesday for who it says should be prioritized.There are two tiers of groups it says should go before the general public. No surprise, the first tier includes front line health care workers taking care of coronavirus patients, people over 65, those with underlying health conditions and their caregivers.Also noted are people who work in the vaccine industry and those who will be administering them. Also, school, food supply and public transportation workers.One issue with that first tier is that's a lot of people, more than 90 million by some estimates.“So, it’s quite possible when a vaccine is available, there won’t be enough available for everybody in this top tier and so there may need to be prioritization within this top tier,” said Dr. Eric Toner, senior scholar at the Johns Hopkins Center for Health Security.The second-tier group includes other health care workers, people living in remote locations without access to quality care, and other essential workers like delivery, military, and first responders.It also includes people who live in places where they can’t socially distance, so inmates and people in shelters.The framework also mentions this is a decision that shouldn't only be made by experts and officials.“The public needs an opportunity to weigh in on this because, after all, they are the ones who are the recipients of the vaccines and whether they get it or not,” said Toner.The good news is the scholars don't see cost as a barrier to the vaccine. And while a vaccine is the best hope for controlling the pandemic, it will not be a magic bullet right away.“If we have a vaccine sometime this winter that’s authorized, it will be many months before everybody has access to it,” said Toner.Some decisions about who gets the vaccine first can't be made until one is ready, because you need to know how it may impact groups like the elderly or pregnant women. 2055

While many think of NASA as the government agency that sends scientists into space, some of NASA’s most important work frequently is used to help people on Earth.In recent months, NASA has used its extensive network of scientists and researchers to combat the coronavirus. And in short order, the agency provided patients and healthcare providers with tools that may have been used to save lives.This week, NASA outlined a number of innovations the agency developed to support the fight against the virus.NASA created an open source for N95 respirators so people can make their own masks by using 3D printers. N95 respirators are unique as they protect the wearer from the virus. NASA’s designs were engineered to meet or exceed standard N95 performance, can be used for different purposes, are compatible with commercially-available filters, and do not disrupt the supply chain.If you have access to a 3D printer, here is how to create an N95 respirator designed by NASA.In addition to NASA’s open-source N95 respirators, the team from Johnson Space Center developed and tested a sterilization protocol to combat a national shortage of N95 masks. This allows N95 respirators to be reused by healthcare providers.“I had a very deep and personal connection to the evaluation (of N95 masks), because my wife is a medical professional… on the frontlines, with only one mask allocated for her to use and re-use daily,” said NASA engineer and project lead Jeremy Jacobs. “She has been very concerned about cross contamination between patient-to-patient and to our family.”Among other innovations, NASA’s Jet Propulsion Laboratory in California designed a new high-pressure ventilator tailored specifically to treat COVID-19 patients. It was designed to treat patients who might not require a full-featured ventilator, keeping the nation’s limited supply of traditional ventilators available, NASA said.NASA’s Armstrong Flight Research Center in California joined several other agencies to create a helmet that functions like a continuous positive airway pressure, commonly known as CPAP, machine to force oxygen into a patient’s low-functioning lungs. 2156

White House officials said Monday that the Trump administration is pursuing another legislative push on immigration, but when pressed said the effort would largely be the same as it has been trying unsuccessfully since last fall.The comments came in a call on Monday with reporters organized to back up a string of tweets from President Donald Trump over the weekend and into Monday pushing a hard line on immigration, sounding off on the Deferred Action for Childhood Arrivals policy, illegal immigration and Mexico.The call, held on the condition the speakers not be quoted by name, largely re-hashed the administration's talking points on immigration, calling provisions of US and international immigration law "loopholes" that human smugglers misconstrue to encourage would-be migrants to make the journey to the US. 838

When United Flight 93 crashed in Shanksville, PA, on Sept. 11, 2001, John Gerula was one of the first on the scene as a volunteer firefighter. The experience inspired John, still in high school, to enlist in the Marines. He shipped out to Iraq two years later, and today he bears the invisible wounds of war.Over the course of 18 months in Fallujah and Operation Phantom Fury, Gerula survived 21 improvised explosive device blasts, resulting in a severe traumatic brain injury that gave him migraines and memory loss, and post-traumatic stress that left him anxious, isolated and abusing alcohol.“I would spend a lot of time by myself at home on my property, just away from people,” Gerula says. “I didn't like large crowds, just the things that brought me back to what caused my issues, the flashbacks and everything.”That all changed this summer when Oliver, Gerula’s service dog, came into his life.”He can sense when I start to breathe heavy, when my heart rate's high, things of that nature, he comes up to me allows me to pet him,” Gerula says. “Since I’ve had Oliver, I’ve not had a drop of alcohol. I gave up drinking altogether. So he has made huge changes in my life.”Gerula and Oliver are among the first four pairs of veterans and service dogs to graduate from American Humane’s “Shelter to Service” program, created to combat the staggering statistics of 20 veterans committing suicide daily due to PTSD and TBI, and the 670,000 dogs euthanized every year in America’s animal shelters.“We saw a great opportunity to uplift the healing power of the human-animal bond by taking incredible dogs who were abandoned, who needed a second chance at life, giving them unbelievable, rigorous training, and then matching them with our veterans, allowing these veterans a chance for healing, hope, compassion, and love,” says American Humane’s President and CEO Robin Ganzert.Ganzert’s organization is currently training its second “Shelter to Service” class while advocating for a bill on Capitol Hill to establish national training standards and speed up the service dog waitlist, which currently runs from 18 to 24 months.And Gerula has a message to veterans seeking the help with their own struggles.“Don't give up,” he says. “The best thing to do is to keep going and just go do every option you can.” 2346
