What are Adenovirus vaccines?

A genetically modified virus is used in the adenovirus vaccines to carry a code for the cells in the body to produce the coronavirus’ spike protein, which is used to enter the host cells by the virus, and this is anticipated to help the body identify this spike protein as a foreign substance and produce an immune reaction against it so that the virus can be eliminated when it attempts to infect the human body.
