If you get the last vaccination one month early it will not count as a completed series because it would have been given outside of the recommendations for the series. It would be no different than if a child received his/her vaccine outside of the schedule...it would have to be repeated in order to be considered valid by the schools or the CDC.
On the CDC website, it just says the 3rd dose needs to be given at least 2 months after the 2nd dose and at least 4 months after the first dose...
Check with your school and your PCP. It may depend not only on your school's policy but also the policies of the clinical facilities. It's also possible that your PCP might not want to administer dose #3 early.
For my school we had to have at least the first two shots completed before starting clinical rotations as long as the 2nd shot was administered before the start of classes. (Some students did not have a definite admission until right before classes started.)
From the CDC website "Primary immunization consists of 3 doses, given at 0, 1, and 6 months." There are accelerated schedules (and even a 2 dose vaccine (combo of Hep A & B) but that is only licensed for those age 11-15) but 0, 1, & 6 months is the standard.
We had to have at least two shots completed before we started clinical rotations. But not all clinical sites accepted students who didn't have the 3-dose series and a titer showing immunity. Those students were rotated to other facilities.
The Advisory Committee on Immunization Practices (ACIP) states that the minimum dosing schedule for Hep B is as follows: 4 weeks between 1st injection and 2nd, 8 weeks between 2nd and 3rd, with at least 16 weeks between the 1st and 3rd. You can view this information on the vaccine specific recommendation heading under the ACIP recommendations page.

I need to have my Hepatitis B vaccine series completed by mid-January. I got the first shot mid-August, thinking that would be enough time... I went back today for the second shot and realized that I would be one month short (i.e. if I got the third shot mid-January, I would be getting it 5 months after the first shot... one month too soon). Would there be serious complications from getting the last injection one month too soon? I need to have the series completed before beginning clinicals. Any advice on this is appreciated!
