Mechanism of Action. Hiberix is a non-infectious vaccine used to prevent Haemophilus influenzae type b (Hib) infection in children. The vaccine works by causing the body to produce its own protection (antibodies) against the disease.
HAVRIX (Hepatitis A Vaccine) is a sterile suspension of inactivated virus for intramuscular administration. The virus (strain HM175) is propagated in MRC-5 human diploid cells. After removal of the cell culture medium, the cells are lysed to form a suspension.
