I am not sure about America but in India, I was a child during covid, 7th grade - 8th grade and i didn't have a vaccine but my school students just one grade above us were called in school and they were asked for vaccine.

Though, to be fair, my whole family caught a "virus" during 2nd phase except my father but we didn't go to hospital and just bed rest for 2-3 days. My family really were skeptical of vaccine but personally I don't mind vaccines and would prefer it.
