Ok, I get it, wrong place for a joke, though the general concept of a vaccine is to infect you with a weak/dead version of the agent causing the infection causing the body to learn how to fight the real thing.
mRNA vaccines do differ in that they send in building blocks for the body to produce the weak strain itself.
