On August 6, local time, Michael Ryan, the head of WHO's health emergency project, said that there are currently about 165 vaccines in the world in the trial phase, 26 are in clinical trials, and six are in phase III clinical trials. Species come from China. Ruian said that the entry of the vaccine into phase III clinical trials does not mean that the development is about to succeed. This means that for the first time the vaccine is being tested in more healthy people to see if the vaccine can protect them from natural infections.
