 Who: more than 20 new crown vaccines are under development in a few weeks or with results


u25b3 Tan Desai, director general of the World Health Organization

Tan Desai said that despite the global spread of the epidemic, Chinas experience has proved that as long as strong measures are taken to detect cases as early as possible, to take isolation treatment and track the contact population, there is still an opportunity to curb the spread of the virus and avoid it becoming a pandemic. At present, the biggest enemy is not the virus, but fear, rumors and stigmatization. What is most valuable is fact, reason and unity.

New drug development, novel coronavirus pneumonia and new vaccine are three ways to fight against new crown pneumonia, but all of them need to undergo rigorous and complex processes. For example, new drug research and development needs to go through three stages: drug discovery, preclinical research and clinical research. It will take at least 10 years, with an average cost of more than 2 billion US dollars. In the sixth edition of the treatment plan, lopinavir and ritonavir have been used for antiviral treatment.
