Immunization records have been kept since the 1960's. How old are you?
I guess the sarcasm went over your head.
Old enough to have my original vaccination records from the 60s and know that current records are kept digitally and that paper copies are usually only provided upon request.
That being said, who is going to be "checking" for current vaccinations on the streets of Rockland County? What happens if someone can't produce their "papers"?
