Description

For sample adults who had ever received the hepatitis B vaccine (SHOTHEPBEV), SHOTHEPBNO indicates whether they had received at least 3 doses of the vaccine, or less than 3 doses.

The survey form included the following information on the vaccine, which interviewers were to read "if necessary":

Approximately 90 percent of people achieve immunity from hepatitis B after 3 doses of the vaccine. The U.S. Task Force on Adult Immunization recommends that adults have a blood test to determine whether they have achieved immunity from hepatitis B, 1 to 6 months after receiving three doses of the vaccine. If blood test results indicate the person is not immune (i.e., titer is not greater than 10 milli-International Units per milliliter of surface antibody in the vaccine recipient), the Task Force recommends the administration of an additional dose and a follow-up blood test. Up to 3 additional doses of hepatitis B vaccine may be administered to achieve immunity.
