Havrix Hepatitis A Vaccine Description

Havrix inactivated vaccine is a sterile suspension of inactivated virus strain HM175, propagated in MRC-5 human diploid cells. After removing the cell culture medium, the cells are lysed to form a suspension. This suspension is purified through ultrafiltration and gel permeation chromatography procedures. Treatment of this lysate with formalin ensures viral inactivation.

Initial U.S. Approval: 1995; Proper Name: Hepatitis A Vaccine, Inactivated: STN: BL 103475

Havrix Hepatitis A Vaccine Indication

HAVRIX is a vaccine for active immunization against disease caused by the hepatitis A virus (HAV). HAVRIX is approved for use in persons 12 months of age and older. Primary immunization should be administered at least 2 weeks before expected exposure to HAV.

Severe allergic reaction (e.g., anaphylaxis) after a previous dose of any hepatitis A-containing vaccine or to any component of HAVRIX, including neomycin, is a contraindication to the administration of HAVRIX.

Immunocompromised persons, including individuals receiving immunosuppressive therapy, may have a diminished immune response to HAVRIX. And vaccination with HAVRIX may not result in protection in all vaccine recipients, says GSK.

Children and adolescents: A single 0.5-mL dose and a 0.5-mL booster dose were administered between 6 to 12 months later. Adults: A single 1-mL dose and a 1-mL booster dose administered between 6 to 12 months later. Primary immunization should be administered at least 2 weeks before expected exposure to HAV.
