Long-Term Study on Safety and Immunogenicity of HEPLISAV™ and Engerix-B® in Adults With Chronic Kidney Disease

An Observational Study Evaluating the Long-Term Safety and Immunogenicity of HEPLISAV™ Compared With Engerix-B® in Adults With Chronic Kidney Disease Who Have Previously Received At Least One Hepatitis B Vaccine Series

The purpose of this study is to determine the durability of seroprotection of HEPLISAV™ and Engerix-B® and the number of injections of each vaccine needed to maintain seroprotection in a cohort of chronic kidney disease (CKD) patients over time.
