You are correct. Instead of messenger RNA that enters the cell and directs protein synthesis; AstraZeneca, Sputnik V and Johnson and Johnson vaccines are adenoviruses that are engineered. The coronavirus spike gene is inserted directly into the virus’s genetic material. My error.
“Unlike the Pfizer-BioNTech and Moderna vaccines, which store the instructions in single-stranded RNA, Sputnik V uses double-stranded DNA.”
The modified virus after injection enter the cell’s nucleus to modify the genes like viruses do to reproduce themselves but instead they produce mRNA that then directs the assembly of the spike protein by the cell.
Besides old age, I also blame omissions and confusion in the media that appears to be intentional.
