For example: I received my first Moderna vaccine and did not have an immediate reaction. I did get very sick and develop and rash a week later. Yesterday, I received my second vaccine and within twelve minutes started having an allergic reaction. My entire body was on fire and my throat and tongue were swelling. They used an epipen and sent me to the hospital.
What happened between the first dose and the second dose? Why would the body react so differently? It was absolutely terrifying. No one has been able explain why I didn’t have a reaction the first time.

Not a doctor, but it sounds like an allergic reaction. You didn’t react to the first dose because you weren’t sensitive to it yet. Some people become allergic to certain substances over time with more exposure. Some never become sensitive, no matter the amount they are exposed to.
