>>120729203Normal vaccines work by introducing an inactive version of the virus into the body so the immune system can recognize the surface structure of the virus and create anto-bodies in response.
An mRNA vaccine introduces temporary genetic code into the body that direct cells to fold proteins in a manner that are supposed to look kind of like what they think the surface of tha actual COVID-19 virus look like, and hope both the immune system picks up on them, produces antibodies as a result, and also that its structure looks close enough to the actual virus that the actual antibodies are effective.
That's why it's not a vaccine in any traditional sense.
