GAITHERSBURG, Md. -- Under the fluorescent lights, inside a series of labs, researchers believe they may have cracked the code to create a vaccine for the new coronavirus, which has officially named COVID-19.“It’s rapidly evolving,” said Dr. Gregory Glenn, president of research and development at the Maryland-based company Novavax. “As a company, we are very invested in looking at how to protect people against infectious diseases.”Novavax is one of several pharmaceutical companies around the world, racing to develop a vaccine for the strain of the coronavirus, which recently emerged in Wuhan, China.“We have to puzzle-solve with vaccines,” Dr. Glenn said. “We think about: what do we want to have the immune response to target? Because that should block the infection and stop the illness and that’s the goal here.”He showed a three-dimensional computerized depiction of what the virus looks like.“The coronavirus – corona being ‘crown’ – has spikes,” he said. “Those spikes have a very important function. They let the virus bind to the human cell and then those spikes act as a syringe to inject genetic material into the human cell.”A vaccine would potentially stop that process, thereby protecting a person from the coronavirus.“We have the gene, we have the vaccine, we’re going to move it into animal testing shortly,” Dr. Glenn said. “Our goal is in late spring to be testing in humans.”It normally takes about 18 months to get human trials started on a vaccine. This shorter time frame is nothing new for the company; they developed an Ebola vaccine within 90 days ready for testing – but there’s a catch.It can take years for a vaccine to get approved, but under dire circumstances sometimes they can be used through something called “expanded access” or “compassionate use” – meaning, the vaccine can be used in humans, before it’s fully licensed.“That happened with Ebola – they didn’t have a licensed vaccine, but they were able to use it under ‘compassionate use,’ they developed evidence that it was working,” Dr. Glenn said.As for a fully approved coronavirus vaccine, experts say that would take longer.“A vaccine in a year would be record-setting time, but not in time to probably have much impact for this disease outbreak,” said Dr. Eric Toner with the Johns Hopkins Center for Health Security.However, if the coronavirus sticks around or comes back stronger in a second wave of the disease, Dr. Glenn said they want to be ready.“We know time is of the essence here,” he said.So far, approximately 73,000 people have been infected and more than 1,800 people have died from the most recent strain of the coronavirus. 2653

GARY, Indiana — An Indiana family is upset after their son was given a "Most Annoying" award at school. Eleven-year-old Akalis Castejon is autistic and non-verbal and works with special education teachers at Bailey Preparatory Academy in Gary, Indiana. Because he is non-verbal, he will often rock back and forth as he struggles to express himself. At the end-of-the-year lunch, his parents were shocked when a teacher handed the fifth-grader an award trophy labeled "Most Annoying Male." Other awards that were given out at the event had much more positive connotations, such as "Best Student" and "Most Improved."The boy's father, Rick Castejon, says he's grateful his son did not understand what was going on but wants an apology from the teacher. "When they called him up, he was just excited to get a gold star because it was shiny," Castejon said. The Gary Community School Corporation released a statement saying they do not condone this type of behavior and will continue to put the well-being of their students first. 1039

  

HONG KONG (AP) — Pet cats and dogs cannot pass the new coronavirus on to humans, but they can test positive for low levels of the pathogen if they catch it from their owners. That's the conclusion of Hong Kong's Agriculture, Fisheries and Conservation Department after a dog in quarantine tested weakly positive for the virus Feb. 27, Feb. 28 and March 2, using the canine's nasal and oral cavity samples. A unidentified spokesman for the department was quoted in a news release as saying. "There is currently no evidence that pet animals can be a source of infection of COVID-19 or that they become sick." Scientists suspect the virus known as SARS-CoV-2 that causes the disease originated in bats before passing it on to another species, possibly a small wild mammal, that passed it on to humans. However, experts from the School of Public Health of The University of Hong Kong, the College of Veterinary Medicine and Life Sciences of the City University of Hong Kong and the World Organisation for Animal Health (OIE) have unanimously agreed that the dog has a low-level of infection and it is "likely to be a case of human-to-animal transmission." The dog, and another also in quarantine which has tested negative for the virus, will be tested again before being released. The department suggested any pets, including dogs and cats, from households where someone has tested positive for the virus should be put into quarantine. In general, pet owners should maintain good hygiene, including washing hands before and after handling animals, their food and supplies and no kissing them. People who are sick should avoid contact with pets and a veterinarian's advice should be sought if changes in a pet's health conditions are detected. "Apart from maintaining good hygiene practices, pet owners need not be overly concerned and under no circumstances should they abandon their pets," the spokesman said. 1919
