Would a dose of 1 ml of 10 mcg Engerix B (2 vials of the Pediatric dose) be the same as 1 ml of 20 mcg (1 vial of the Adult dose)?
The pediatric formulation of Engerix-B is not licensed by FDA for use in adults. Adults 20 years of age and older should receive 1 mL (20 mcg) of the adult formulation of Engerix-B. With Recombivax HB, two pediatric doses can be used in place of an adult dose, because Recombivax is licensed for that usage.
