How are the COVID vaccines different from other vaccines on the market?
The COVID vaccines are mRNA (messenger RNA) vaccines, which are completely new. No mRNA vaccine has ever been licensed for human use before. There are no other therapies or prophylactics on the market that use the same approach, despite a handful of efforts.
Traditional vaccines introduce pieces of a virus (“live” or inert), as well as adjuvants such as aluminum and mercury, to stimulate an immune reaction. The new mRNA vaccine is completely different. It actually injects (transfects) molecules of synthetic genetic material from non-human sources into our cells. Once in the cells, the genetic material interacts with our transfer RNA (tRNA) to make a foreign protein that supposedly teaches the body to destroy the virus being coded for. So the vaccine is hijacking the protein-makeup machinery.
