@baseballHS,
sorry for slow reply - busy at work today. I did some poking around, and it doesn't seem like every college allows those vaccine waivers you mention. I checked Penn State and U Penn -- Penn State (public) does allow any student to choose to waive vaccines, but U Penn (private) only allows medical and religious waivers, not the more generic waiver you describe. I'm guessing that these rules vary by state, and also by education level (K-12 vs Higher Education). My native state of CA only allows medical waivers for K-12 vaccines. Bottom line -- young folks with strong feelings about vaccines would need to check the policies of the specific colleges they are considering.
