isolated anti hbc

[sb6845]

I applied to a health center for hepatitis b blood tests a year ago, they only checked for HBsag and antiHBs but not for anti HBc. And i had my vaccination done.Then i learned about the situation of having isolated anti hbc from the internet. i had another test a few days ago.Now the results are as follows;
HBsag negative, anti HBs Positive. Anti HBc Negative.
My question is:
1.is it possible i had the virus before and infected somebody else?
2.Or  Anti hbc isn't effected by the vaccination and was negative then too, and i never had the virus?
