ENGERIX-B will not prevent hepatitis caused by other agents, such as hepatitis A, C, and E viruses, or other pathogens known to infect the liver. Immunization is recommended in persons of all ages, especially those who are, or will be, at increased risk of exposure to hepatitis B virus,1 for example: Infants, Including Those Born of HBsAg-Positive Mothers (See DOSAGE AND ADMINISTRATION.) Adolescents (See CLINICAL PHARMACOLOGY.) Healthcare Personnel: Dentists and oral surgeons. Dental, medical, and nursing students. Physicians, surgeons, and podiatrists. Nurses. Paramedical and ambulance personnel and custodial staff who may be exposed to the virus via blood or other patient specimens. Dental hygienists and dental nurses. Laboratory and blood bank personnel handling blood, blood products, and other patient specimens. Hospital cleaning staff who handle waste. Selected Patients and Patient Contact…
