UW HSIP- Subsequent HepB Add’l Dose #1

1 min. readlast update: 10.22.2025

You have submitted a negative/non-reactive HepB Surface Antibody titer indicating you do not have immunity to HepB. Your next action is to complete a single additional HepB dose and then a repeat Quantitative HepB Surface Antibody titer in 1 month.

HSIP recommends completing a Heplisav-B vaccine dose since it is known to boost antibody responses significantly. If the Heplisav-B is not available, then any HepB dose is accepted. 

Once approved, a post-vaccination Subsequent HepB Repeat Titer tag will be created. You will need to complete a post-vaccination Quantitative HepB Surface Antibody Titer one month from the additional HepB vaccine dose. 

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