What meib92 said. Program requirements may differ by school, but from what I've seen, most will accept proof of vaccination for MMR, tetorifice (within ten years), & varicella, some require HepB titers to be done even if you can prove completion of the series, especially if it was finished over ten years ago, and many will make you show or several years of TB tests, or a 2-step in the last year.
