Hepatitis B
For Adults (Including HBV Screening)

We’re thinking of using Twinrix and we’re wondering whether we can use it for doses #1 and #3 only and use single antigen hepatitis B vaccine for dose #2?

No. Twinrix contains 50% less hepatitis A antigen component than Havrix, GSK’s monovalent HepA [720 vs. 1440 El. U.], so the patient would not receive the recommended dose of HepA antigen.
