Immunogenicity, antibody persistence, and safety of the 60 μg hepatitis B vaccine in hemodialysis patients: a multicenter, randomized, double-blind, parallel-controlled trial
Background: To evaluate the immunogenicity, antibody persistence, and safety of the 60 µg hepatitis B vaccine in hemodialysis patients in China.
Methods: We conducted a multicenter, randomized, double-blind, parallel-controlled trial including 352 hemodialysis patients who were centrally randomized in a ratio of 1:1 to receive a 20 µg (IM20 group) or 60 µg (IM60 group) recombinant hepatitis B vaccine at months 0, 1, and 6.
Results: The vaccine-elicited antibody responses peaked at month 7, and declined at month 12. At month 7, the IM60 group had stronger GMC of anti-HBs, and a higher proportion of seroconversion and high-level response than the IM20 group did (P < 0.05). Better immune responses were observed in the IM60 group, especially for those aged or in the high-frequency hemodialysis population.
Conclusion: The high dose 60 µg recombinant hepatitis B vaccines elicited stronger immune responses than the 20 µg hepatitis B vaccine did among hemodialysis patients.
Clinical trial registration: ClinicalTrials.gov, number NCT02963714.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform.
