Hepatitis in clinical practice. 1. Hepatitis A and B.

As is evident from the foregoing discussion, hepatitis A and hepatitis B are not static, passé disease. Knowledge concerning these illnesses continues to expand at a fantastic rate--all of it of extreme practical clinical significance. Most interesting is the elucidation of the etiology of the acquired immune deficiency syndrome (AIDS) and the increase this knowledge is hoped to produce on the utilization of hepatitis B vaccine. Also extremely important is the development of recombinant DNA vaccine, which will permit total circumvention of the question of AIDS and safety of the hepatitis B vaccine.
