The vaccine uses messenger RNA to get cells in your body to produce the spike protein that is on the COVID virus. This is to train your immune system to recognize and build immunity to the COVID virus. If your dose of the vaccine is successful, this can eliminate or greatly reduce the virus' ability to infect you.
The virus uses messenger RNA to get cells in your body to produce more full viruses - this is how viruses reproduce in your body and spread the infection. This comes with potentially very serious illness and potentially death.
The difference is clear.
Thanks for the mRNA theory stuff, but this is a rushed EUA vaccine untested long-term for safety or efficiency.
The alternative is a virus with a 0.0415% chance of hospitalization symptoms (Pfizer study).
