Hi there, I actually spoke with someone from Student Wellness yesterday, and she said if you have the first 2 immunizations done by the start of classes you will be fine. Apparently that won't affect the time period of clinicals. I still am not sure when clinicals start. I don't know if you have had your 3 series Hep B previously or not, but this info might be helpful for you. If you already have had your Hep B 3 series of vaccinations but no titer drawn, then you need to get a Hep B titer. If the titer is positive for antibodies, you are good to go. You will need to document the titer and 3 series. They just put on paper that it needs to be 4-6 weeks after the 3rd, but apparently this doesn't matter. If your titer is negative, you will then need to get the series again. If the titer is questionable as to whether or not it is pos or neg then you have to get a booster.
