She didn’t travel though, the family remained in WA state from 1955 until after her graduation from high school in June 1960, when the family moved to HI. All of her previous travel was within the U.S. For those of us who did travel immunizations were a necessary evil often given too often when encountering different controlling entities which argued their vaccine was stronger than one given previously by another entity! I know that because I had so many needless tetanus shots given that I developed a somewhat severe reaction to tetanus shots!
How do you know she didn’t travel outside the US with her parents before 1960?
What about Ann Dunhams middle school schooling in Beirut, Lebanon, Notre Dame de Jamhour?
