Here's the 'official' leader in the COVID-19 vaccine race

When the World Health Organization (WHO) says that a given anti-coronavirus product is a leader, that's about as official as it gets in the fast-moving world of COVID-19 therapies and vaccines. Earlier this year, a top WHO executive stated that Gilead Sciences' remdesivir was the leading therapy targeting COVID-19. Remdesivir, of course, has now become the de facto standard of care for the novel coronavirus disease.
