I have read on this forum countless times (specifically from one poster) that the mRNA vaccines are not vaccines. If I recall correctly, there is intimation that these vaccines are actually gene therapy. Seems these vaccines are referred to as "vaccines" everywhere with the exception of the poster on this forum.
Here is an article that debukes that the mRNA vaccines are gene therapy. I apologize if you don't think the source I used is reliable. I did look up the bias rating on Forbes and they are middle of the road so really no bias there...............
