Mortality follow‐up of the 1942 epidemic of hepatitis B in the U.S. Army
James E. Norman, Gilbert W. Beebe, Jay H. Hoofnagle, Leonard B. Seeff – 1 October 1993 – The hypothesis that adult infection with the hepatitis B virus in the United States leads to a carrier state with a high risk of primary liver cancer was tested in two ways: (a) a cohort mortality study of U.S. Army veterans given yellow fever vaccine contaminated with hepatitis B virus in 1942 and controls and (b) a case‐control study comparing veterans with hepatocellular carcinoma in Veterans Affairs hospitals with matched controls with respect to receipt of contaminated vaccine in 1942.
