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.

It’s not uncommon for your body to react more strongly to something after repeat exposures. It’s not exactly the same, but that’s also sort of what’s happening when you get repeated doses of a vaccine: your immune response to the disease gets stronger (although the allergic reaction is a different kind of reaction).
