My arm got a bit sore and had a mild headache, some body aches, and felt a little fatigued. Knowing what I knew, I realized that my symptoms were a sign that my body was mounting an immune response to the vaccine and therefore I am developing immunity against COVID-19. After 48 hours, all my symptoms vanished and I am doing fine now. I am grateful for the amazingly efficient systematic vaccination procedure and would urge each one of you to get vaccinated
