This danger is stilll becoming increased for those medial workers who are more exposed in their everyday work to contaminated human blood or other biological materials. Therefore, the health institutions must introduce prevention measures against possible infection, but also the protection procedures to be applied immediately before and after incidental exposition to infectious material. They are especially essential at the occasion of incidental injuries of the persons by medical instruments which had been in the contact with blood. That is why it is obligatory for the employees of the health care institutions to be vaccinated against possible infection by Hepatitis B.
