Hello and welcome to ehealth forum.

Transfusion reactions occur when antibody in the serum of recipient reacts with the antigen on donor's red blood cells.
As O blood group does not have any antigen on its RBS, it is safe to be Transfused to A blood types provided they are Rh compatible aswell

I hope it helps
