People seem reassured by the fact that there is no covid virus in the vaccine. I am the opposite. I think there is some legitimate scientific reasoning behind the idea of "like cures like" when it comes to the immune system. Exposing the body to just enough of something so that it mounts its own defense.
Tricking the body sounds riskier.
Perhaps because I don't believe you can "trick" the body without some type of long term consequence. . Or nature for that matter.
