immunizations

I recall reading that for the academies there were certain immunizations that were mandatory. Does anyone know if that is the same for NROTC students? Aside from the usual ones for high school, I was wondering whether my DD is required to get 'optional' ones for hpv protection or any others?

DS has never been vaccinated and will be starting them tomorrow. I cannot seem to find what is actually required for admittance, or at least to have them started before R-Day. Does anyone have this info? Also tried call WP multiple times and could not get a live nurse. Thanks!
