The purpose of this trial is to determine if there is an improvement in the immune response of older adults over 50 years of age using a modified process hepatitis B vaccine and a currently licensed hepatitis B vaccine (RECOMBIVAX HB™).
Allocation: Randomized, Control: Dose Comparison, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Prevention
Comparator: RECOMBIVAX HB™ Hepatitis B Vaccine (Recombinant), Comparator: Modified Process Hepatitis B Vaccine (Experimental), Comparator: ENGERIX-B™ (currently licensed product)

To assess the safety and immunogenicity of a booster dose of hepatitis B vaccine in children who have received a 3-dose primary series of either RECOMBIVAX HB or ENGERIX-B. The primary vac...
Hepatitis B Vaccine [Recombinant] is a well-established vaccine which has been used extensively, worldwide since its initial licensure in 1986. Hepatitis B vaccines:  induce protection ...
This study was conducted in healthy infants and will provide new immunogenicity and safety data for the modified process hepatitis B vaccine. This study was conducted to address the follo...
To determine if there is an improvement in the immune response to HBsAg (hepatitis B virus) in healthy infants using a modified process in a combination Haemophilus Influenzae, type b/Hepa...
A study to test the safety, tolerability, and efficacy of 4 regimens of vaniprevir + Peg-IFN and RBV as compared to placebo + Peg-IFN and RBV.
Our ability to detect statistical dependencies between different events in the environment is strongly biased by the number of coincidences between them. Even when there is no true covariation between...
Hepatitis B vaccines are highly effective in preventing hepatitis B virus infection and have been included in the national immunization program of Japan since 2016. Heptavax®-II is one of two hepatit...
Vaccine failure with chronic hepatitis B virus (HBV) infection still develops in children after universal hepatitis B immunization. This study aimed to investigate the natural course of chronic HBV in...
Hepatitis B virus infection remains an important public health problem in the United States. Currently approved alum-adjuvanted vaccines require three doses and have reduced immunogenicity in adults, ...
Any vaccine raised against any virus or viral derivative that causes hepatitis.
INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).
A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).
A species in the genus HEPATOVIRUS containing one serotype and two strains: HUMAN HEPATITIS A VIRUS and Simian hepatitis A virus causing hepatitis in humans (HEPATITIS A) and primates, respectively.
INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
