Vaccine begins human trials


The novel coronavirus vaccine was first tested in Seattle on 16 March, National Institutes of Health. The first anonymous experimenter was vaccinated at the Kaiser Permanente Institute in Seattle. Public health officials say 45 young healthy volunteers will take part in clinical trials and inject different doses of reagents. All volunteers will not have the risk of infection because the reagent itself does not contain viruses. The first stage of the experiment is purely to verify the safety and side effects of the vaccine, and to accumulate data for larger experiments. Vaccine trials can take as long as 18 months. At present, more than 10 research institutions around the world are accelerating the development of related vaccines.
