Most like the MMR are given as a child, same with with chicken pox vax, unless you had chicken pox then they take your word for it. Tdap is a normal one for all adults to have every 10yrs, the Hep A and Hep B are newer. Hep B used to be given in 7th grade to kids (at least when mine were in school). Hep A and B are an issue here in many parts of the US, that's why it's being mandatory. They give it to newborns babies, unless you're me and tell them no.
