In brief: Depends on dose

Immunoglobulin preparations are not checked if they have protective level antibodies anti-hepatitis a.
Assuming that most blood donors have enough antibodies anti-hepatitis a, the immunoglobulin preparations should also have enough to neutralize a potential infection. However, this is especulation and it is possible that there could be enough viruses to overcome the neutralzing antibodies received.
