I am a doctor and I now know the truth about vaccines!
But sheep will dream up any EXCUSE needed to deny her speaking truth. Fear creates denial it's just a shame the kids are the ones who pay for those ewww conspiracies.
Theoretically, vaccine usually contains an agent that resembles a disease-causing microorganism.

Body's immune system is stimulated to recognize the agent as a threat and destroy it, and any of these microorganisms that it later encounters.
