The world's biggest COVID-19 vaccine test got underway Monday with the first of 30,000 planned volunteers. The experimental vaccine is made by the National Institutes of Health and Moderna Inc. It's one of several candidates in the final stretch of the global vaccine race. Officials are seeking to find out whether more people who get dummy shots become infected than those given two doses of the real vaccine. The U.S. government plans separate huge studies of several leading vaccine candidates through fall, each in hot spots where the virus still is spreading.Dr. Anthony Fauci and other Trump administration officials have said that the company is already producing millions of doses of the vaccine in the event that it receives Emergency Use Authorization from the FDA following the trial. Fauci remains cautiously optimistic that a vaccine could be available by January of next year — though it's unclear how long it would take for a vaccine to be available for all Americans who want it. 1004

The shape of the Earth is a spheroid, right? A YouGov study conducted this year says a third of people ages 18-24 aren’t sure our planet is round."If you believe we live on a globe, I know you're deceived." Welcome to the Flat Earth International Conference. “NASA has obviously lied to us on numerous occasions,” says Wendell, a conference attendee.Most of the people gathered at the conference held in Denver, Colorado believe Americans live on a lie. The flat Earth believers think pictures of the earth are fake and astronauts are actors. Social media sites like YouTube have made the flat earth theory more available in recent years. Some of those accounts have tens of thousands of followers."If you do trust your senses, you're seeing things different than what you're being fed," says Debra Auden, who traveled from Texas to the conference.Dr. Ka Chun Yu, the curator of space science at the Denver Museum of Nature and Science, says he was really surprised when he heard about the number of flat-earthers."We've known for over 2,000 years that the earth is more or less a sphere, a ball or a round shape."This is how the Greeks knew the earth was round. They realized that if you had sticks in the ground and you were able to measure their shadows on the same day, the lengths of the shadows would actually be different," Dr. Yu says.But to flat-earthers, science's facts are fiction. Flat Earth believers say an ice wall keeps us from falling off the surface.So, why do flat-earthers believe there would be such a lie about a round Earth? Some say conspiracy, while others turn to God. "You might not be convinced, but I encourage you to visit your local science museum or planetarium," Dr. Yu says. 1752

The way doctors treat asthma in both children and adults just got a major update.Speaking to the Journal of the American Medical Association, respiratory experts said the changes in guidelines focus on six key areas, including improving asthma diagnosis, management, and treatment.It’s the first published update in 13 years.“So, one of the goals of our update was to address the issue of who can use intermittent inhaled corticosteroids and when used, are they as effective as daily use,” said Michelle M. Cloutier, MD with UConn Health.One of the biggest changes is that many patients may not need to use an inhaler every day anymore.“Especially those families of young children who don’t necessarily buy into using daily medication when their children are having intermittent symptoms,” said Stephanie Lovinsky-Desir, MD, MS with Columbia University Irving Medical Center.The new recommendations for inhaler use vary by age and severity of asthma, so it’s important to talk to your doctor about the new guidelines.Asthma affects nearly 5% of adults and 10% of children.During the pandemic, because of the higher death rate of asthma patients from COVID-19, more people have been seeking treatment for the condition.The average annual cost of asthma per person is more than ,200. But research has also shown among other things, regular use of medication and flu vaccines can reduce the chances of someone with asthma being hospitalized, driving up those costs. 1472
