1 min. readlast update: 10.22.2025

You have submitted three valid HepB vaccine doses for the Accelerated Hepatitis AB (Twinrix) series. Your next step is to complete a final HepB vaccine dose to complete your initial HepB vaccine series and submit the record for approval.  

Make sure to follow the Hepatitis B vaccine dosing schedule for the vaccine type you are receiving if completing your initial Hepatitis B vaccine series:

Accelerated Hepatitis AB (Twinrix) (4-dose series): Doses are given respectively 0, 1 week, 21-30 days, and 12 months. However, students who choose this option should remember that 1 month after the last dose, you will still need to receive the titer to prove immunity.    

 If you have questions, please contact HSIP at myshots@uw.edu.
