The Role of RNA in the Development of Vaccines

The MRNA vaccine, the MRNA, we did not invent it, nature invented, and actually it was invented for the pathogens. The virus has a 29 different protein encoding sequences. We are just selecting one of the 29 protein coding sequence. And this we are using to, as a vaccine, why? Because it goes for a protein which is on the surface of the virus. That could be recognized by the immune system and can neutralize it.
