Hey all!I am currently in the process of doing my health packet for the LVN program. I am pretty confused about the vaccines. I am 25 years old and had these vaccines when I was younger.-2 shots of MMR, one when I was 2 and the other when I was 4.-3 shots of Hepatits B, two when I was 2 (a few months apart) and one when I was 5.i have asked various people about these vaccines including a doctor, nurse practioner, and a nurse. They have all told me something different.How long should each vaccine last and would I need to get it again? The school I'm going to just wants proof of the vaccines or titers. I have immunization records as proof but not sure if it I would still need the vaccines again.
