When the WHO investigation report to China was translated into Chinese and published, the most important sentence was “inadvertently” omitted: “Redesvir in the United States is the only effective drug for the treatment of new coronaviruses.”
So WHO has come to the conclusion that Redecive is the only effective drug? I also think that experts cannot really announce whether the data proves to be valid at the end of April as announced. It must be something that has been known after a small-scale experiment. Double blindness is just a process to make the data more convincing to the public.
