For those of you who had it done, don't worry about it now - if you didn't have problems with reactions or anything then you're fine. But it was probably a moot point to have it done if you weren't tested for the virus in the first place to see if you already had it or not. That's why I thought it was bull**** too because unless you were a virgin when you had the needles, then there was a chance that you had already come into contact with the virus, making the whole point of the vaccination, well, pointless.
