Dr. Anthony Fauci – who has been considered one of the most trusted leaders tackling the COVID-19 pandemic in the United States – once again stressed that, as far as the evidence suggests, the novel coronavirus is naturally occurring and was not made in a laboratory.

Moderna Inc. submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration for the company’s mRNA vaccine candidate against the novel coronavirus SARS-CoV-2 to evaluate mRNA-1273 in Phase 2 and late-stage studies if supported by safety data from the Phase 1 study led by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

Gilead Sciences Inc.’s shares surged 16 percent in after-hours trading on Thursday following a media report detailing encouraging partial data from trials of the U.S. company’s experimental drug remdesivir in severe COVID-19 patients.

As the world shifts toward a concept of social distancing as part of an attempt to protect against the novel coronavirus, new research is showing the virus that causes COVID-19 is quite stable on hard surfaces, and even in the air.

Inside the United States, the first clinical trial for a vaccine to the novel coronavirus that causes COVID-19 begins today. The mRNA-1273 vaccine is being developed by Moderna Therapeutics with the National Institute of Allergy and Infectious Disease (NIAID).
