{'blood groups': [3, 1, 1, 2], 'blood group': [2, 2, 0, 1], 'blood transfusion': [1, 0, 1, 0], 'transfusion': [0, 0, 3, 1], 'hospital': [0, 0, 1, 2], 'ab': [0, 0, 1, 0], 'serious accident': [0, 0, 1, 0]}

In this scenario, the safest blood group for immediate transfusion to a person with an unknown blood type is O, Rh-.

The reason for this is that individuals with blood type O are considered universal donors because their red blood cells do not have A or B antigens on their surface. This means that their blood can be transfused to individuals of any blood type without the risk of an immune reaction due to ABO incompatibility.

Additionally, selecting Rh-negative blood (Rh-) further minimizes the risk of potential Rh incompatibility reactions. People who are Rh-negative can safely receive Rh-negative blood, regardless of their Rh status.

On the other hand, individuals with blood types AB, Rh+ or AB, Rh- are considered universal recipients. This means they can receive blood from any ABO or Rh blood type without experiencing an immune reaction.

Therefore, in this scenario, the safest option for immediate blood transfusion would be O, Rh-.
