Declaration of public policy. The availability of scientific knowledge, skills and materials for the purpose of injecting, transfusing or transplanting human whole blood, plasma, blood products, blood derivatives and products, corneas, bones, or organs or other human tissue is important to the health and welfare of the people of this State. The imposition of legal liability without fault upon the persons and organizations engaged in such scientific procedures inhibits the exercise of sound medical judgment and restricts the availability of important scientific knowledge, skills and materials. It is therefore the public policy of this State to promote the health and welfare of the people by limiting the legal liability arising out of such scientific procedures to instances of negligence or willful misconduct.
