I'm sure i got my hepatitis shots when i was young i work in a prison so i got them again then missed the 2 shot by 90days so i had to start over isok?

Don't start over.: your vaccine series does not need to be restarted. You should get the second dose ASAP and be sure that the third dose is separated from the second dose by at least eight weeks. If your job may entail a reasonable chance of coming into contact with hepatitis B infected fluids, you should get hepatitis B markers after the vaccination series is complete. Good luck.
