If hepatitis B vaccine is administered before infection, it prevents the disease and the carrier state in almost all individuals.
Some people should not get hepatitis B vaccine or should wait.
People should not get hepatitis B vaccine if they have ever had a life-threatening allergic reaction to baker’s yeast (the kind used for making bread) or to a previous dose of hepatitis B vaccine.
People who are moderately or severely ill at the time the shot is scheduled should wait until they recover before getting the hepatitis B vaccine.
