Hepa B vaccine experience

what are the consequences if hepa b vaccine accidentally entered the venous route while being injected intramuscularly?

i had an experience, wherein upon injecting of the needle to my deltoid region, and then the nurse pulled the "plunger" of the syringe, but NO blood was aspirated... so she gave the hepa b vaccine. But when she pulled the syringe out, i noticed that there was a few blood which oozed in and appeared in the used empty syringe.

follow-up question: did in anyway hepa b vaccine entered my veins in this case?
