Information in the article “Preventive Strategies in Chronic Liver Disease” (November 1, 2001, page 1555) regarding seroconversion rates in hepatitis immunization was misleading. The first full paragraph in the left column on page 1557 should have been worded this way: “In patients without chronic liver disease, seroconversion occurs in 94 percent of patients following hepatitis A vaccination and 100 percent of patients following hepatitis B vaccination. Vaccination of adults with chronic liver disease of viral or nonviral etiology produced seroprotection rates similar to those observed in healthy adults.²² However, seroconversion rates are lower in patients older than 40 years, in those with end-stage renal disease, alcoholism, and decompensated cirrhosis, and in those with a liver transplant. ⁷”
