Beijing-Sana
Researchers at the Chinese company "Kansino Biologics" revealed that a vaccine that was tested in humans for the first time proved that it was safe and led to a rapid immune response in its recipients.
The results of the researchers published in the medical journal "Lancet" showed that 801 adults received the vaccine and appeared to have neutral antibodies, and the cells in their bodies showed a response against the virus, but more studies are necessary to ensure that The vaccine can protect against infection.
Professor Wei Chen said that the vaccine's ability to stimulate an immune response does not necessarily mean that it will protect humans from "Covid 19".
