Can Twinrix (HepA-HepB combination vaccine) be used for people planning international travel?

Yes. If time allows, use the standard Twinrix schedule of 3 doses given intramuscularly on a 0-, 1-, and 6-month schedule. If travel is imminent the accelerated 4-dose Twinrix schedule can be used, which is 3 doses given on days 0, 7, and 21-30 days and a booster dose at 12 months.
