A booster shot of mRNA vaccine reexposes your imune system to a single protein that is present on the virus, allowing your immune system to more readily initiate an immune response should you be exposed. Since you already have two shots, you are protected, and with the booster, your imune system is on high alert for covid-19 virus. If you were exposed, your immune system is ready to fight it off.
