Coronavirus vaccine: How are trials done, safe for humans?
Coronavirus vaccine: How are trials done, safe for humans? The first corona vaccine trial for people across Europe was launched in Oxford, and the first two of over 800 volunteers were vaccinated. Half of the volunteers will receive a Covid-19 corona vaccine and the other half will be vaccinated, which protects them from meningitis, but does not affect the coronavirus. The key to the experiment is this: Volunteers will not know which vaccine has been given to them. Only doctors will know this. The vaccine was produced by a group of scientists from Oxford University in a three-month study period. In what method was the vaccine produced? There are many known methods of producing vaccines. This vaccine was prepared by weakening a normal and harmless flu virus (adenovirus) seen in chimpanzees and replacing it so that it cannot develop in the human body. Scientists have inserted the gene of proteins from the surface of ...
