The US food and drug regulatory body has allowed the emergency use of an investigational anti-viral vaccine to treat COVID-19 patients after some researches, including one led by an Indian-American physician, found that the drug helped recover some of the infected cases faster.

The Food and Drug Administration (FDA) gave emergency use authorisation (EUA) for the use of investigational anti-viral Remdesivir for the treatment of COVID-19 patients. "I'm pleased to announce that Gilead now has an EUA from the FDA for Remdesivir," US President Donald Trump told reporters at the White House on Friday.
