The first participant in a clinical trial for a vaccine to protect against the new coronavirus will receive an experimental dose on Monday, according to a government official.The National Institutes of Health is funding the trial, which is taking place at the Kaiser Permanente Washington Health Research Institute in Seattle. The official who disclosed plans for the first participant spoke on condition of anonymity because the move has not been publicly announced.Public health officials say it will take a year to 18 months to fully validate any potential vaccine. Testing will begin with 45 young, healthy volunteers with different doses of shots co-developed by NIH and Moderna Inc. There’s no chance participants could get infected from the shots, because they don’t contain the virus itself. The goal is purely to check that the vaccines show no worrisome side effects, setting the stage for larger tests.Dozens of research groups around the world are racing to create a vaccine as COVID-19 cases continue to grow. Importantly, they’re pursuing different types of vaccines — shots developed from new technologies that not only are faster to produce than traditional inoculations but might prove more potent. Some researchers even aim for temporary vaccines, such as shots that might guard people’s health a month or two at a time while longer-lasting protection is developed.Also in the works: Inovio Pharmaceuticals aims to begin safety tests of its vaccine candidate next month in a few dozen volunteers at the University of Pennsylvania and a testing center in Kansas City, Missouri, followed by a similar study in China and South Korea.Even if initial safety tests go well, “you’re talking about a year to a year and a half” before any vaccine could be ready for widespread use, according to Dr. Anthony Fauci, director of NIH’s National Institute of Allergy and Infectious Diseases.That still would be a record-setting pace. But manufacturers know the wait — required because it takes additional studies of thousands of people to tell if a vaccine truly protects and does no harm — is hard for a frightened public.President Donald Trump has been pushing for swift action on a vaccine, saying in recent days that the work is “moving along very quickly” and he hopes to see a vaccine “relatively soon.”Today, there are no proven treatments. In China, scientists have been testing a combination of HIV drugs against the new coronavirus, as well as an experimental drug named remdesivir that was in development to fight Ebola. In the U.S., the University of Nebraska Medical Center also began testing remdesivir in some Americans who were found to have COVID-19 after being evacuated from a cruise ship in Japan.For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The worldwide outbreak has sickened more than 156,000 people and left more than 5,800 dead. The death toll in the United States is more than 50, while infections neared 3,000 across 49 states and the District of Columbia. The vast majority of people recover. According to the World Health Organization, people with mild illness recover in about two weeks, while those with more severe illness may take three weeks to six weeks to recover.___The Associated Press receives support for health and science coverage from the Howard Hughes Medical Institute’s Department of Science Education.

The CDC has recently issued guidance indicating that up to nearly one half of antibody tests are inaccurate.While early indications are that having antibodies offers some protection against reinfection, the CDC said too little is known about antibodies to determine whether it is safe for a person to no longer need to conduct social distancing. Additionally, the CDC said that a positive test should not be used at this time to determine if an individual is immune.The CDC added, “Serologic test results should not be used to make decisions about grouping persons residing in or being admitted to congregate settings, such as schools, dormitories, or correctional facilities.”The CDC said that it recommends providers use multiple antibody tests on patients, and it obtains the most accurate tests available.The CDC said that the prevalence of those testing positive for antibodies among the general population is between 5 and 25, with higher figures coming from areas with localized outbreaks. The FDA has also warned that all antibody tests can produce false results, and that “broad use of the tests, when not appropriately informed by other relevant information, such as clinical history or diagnostic test results, could identify too many false-positive individuals.” 1286

The Hubble Telescope can sure find some scary images of deep space in a video released by NASA on Monday. The images were of the twin galaxies AM 2026-424, which is a mere 724 million light-years away from Earth. That means the light we are seeing on Earth was emitted 724 million years ago.From Earth, the colliding galaxies appear to form the shape of a face, with two "eyes," which make up the core of the galaxies."Each 'eye' is the bright core of a galaxy, one of which slammed into another. The outline of the face is a ring of young blue stars. Other clumps of new stars form a nose and mouth," NASA said in a statement.""Although galaxy collisions are common—especially back in the young universe—most of them are not head-on smashups, like the collision that likely created this Arp-Madore system," NASA added. "The violent encounter gives the system an arresting 'ring' structure for only a short amount of time, about 100 million years. The crash pulled and stretched the galaxies' disks of gas, dust, and stars outward. This action formed the ring of intense star formation that shapes the nose and face." 1129

The medical journal BMJ published a report today that links a lower risk of early death to higher levels of physical activity at any intensity in middle-aged and older people.Previous studies have repeatedly suggested that any type of sedentary behavior, such as sitting still, is not good for your health. Being sedentary for 9.5 hours or more a day, excluding sleeping time, is associated with an increased risk of death.Led by Prof. Ulf Ekelund of the Norwegian School of Sports Sciences located in Oslo, Norway, researchers analyzed studies that assessed how physical activity and sedentary time were linked with risk of an early death.Using accelerometers -- a wearable device that tracks the volume and intensity of activity -- to measure total activity, intensity levels were separated into categories of light, moderate and vigorous.Cooking or washing dishes were examples of light intensity, brisk walking or mowing the lawn were considered moderate intensity, and jogging or carrying heavy loads were used as examples of vigorous intensity.The risk of death for participants was approximately five times higher for those who were inactive compared to those who were the most active, according to the researchers.The study was conducted in the United States and Western Europe on 36,383 adults who were at least 40 years old with an average age of 62. Participants were tracked over an average of 5.8 years.However, the findings in the study may not apply to other populations and younger people.At least 150 minutes of moderate intensity or 75 minutes of vigorous physical activity each week are recommended guidelines, 1642

That scene from “Friends” when we find out Ross is still a patient at his pediatrician’s office is getting more common for young adults.One reason is young adults can stay on a parent's insurance until they are 26 years old so it's easier and more affordable to stick with the same doctor.There are downsides though.“If they start to get medical conditions, high blood pressure, hypertension, adult onset diabetes, those more … adult medical conditions, that’s an appropriate time to say, ‘hey maybe it’s time to transition to an adult provider,’ ” said Dr. Christina Johns with PM Pediatrics. The pediatric emergency physician says one benefit of staying on with a pediatrician longer is the patient continues to see someone familiar with their medical history, especially for those with chronic childhood health issues. And she says it prevents the young adults from moving into another trend she's noticing — relying solely on emergency room and urgent care only.“There really does seem to be a large group of adults who use those places as their primary care,” the pediatrician said. “It’s really important to have a relationship with a primary care doctor.”Johns says when young adults become parents and when women need regular OB/GYN care, those are also appropriate times to transition away from a pediatrician.The American Academy of Pediatrics discourages transitioning away from pediatric care solely based on age. Their position is that it’s a decision between a patient and their doctor. It should take into account meeting the needs of the patient and the abilities of the doctor. 1606
