Fauci Calls for US-UK Flights to Remain Open Despite New Strain of Coronavirus: ‘Don’t Overreact’ Mediaite 12/21/2020 Dr. Anthony Fauci is calling for flights between the United States and United Kingdom to remain open despite the reported spread of a new, more contagious strain of Covid-19. “Keep an eye on it,” Fauci advised in a comment to CNN. “Don’t overreact to it.” Experts believe a Covid-19 mutation that has been spreading in the U.K. is up to 70 percent more transmissible than the original version. No research has been conducted on whether vaccines developed by Pfizer, Moderna, or other drug companies are capable of inoculating patients against it.
