I have a question Ladies!

So my boyfriend has Hep C from his mother and I have read that this disease is spread through blood and in very very rare cases Semen and other fluids,I'm 19 and very healthy and I'm pretty sure that I had a vaccine for it when I went to take my phlebotomy classes in November. I was wondering if I could get it because all we have done pretty much in 4 years is just oral and he hasn't done the business in my mouth in probably a year or so. So I was just curious! Thank you
