The primary purpose of this study is to determine the ability of the Protector Cap Jet Injector to prevent cross-contamination in the next injection sample. The hypothesis is that the Protector Cap Jet Injector will prevent contamination in the next injection sample, even following injection of volunteers with high levels of hepatitis B virus.
The jet injector is a needle-free injection device that uses a high-pressure stream to penetrate the skin and deliver medication into intradermal, subcutaneous, or intramuscular tissues. Multi-dose jet injectors are a type of jet injector with a reusable fluid path that consists of the vial adapter, dose chamber, fluid pathway, and nozzle. Although credited with decades of use and the delivery of millions of doses of vaccine in the field, multi-dose jet injectors are no longer used due to evidence of cross-contamination between injections. The HSI-500 Jet Injector with Protector Cap has been designed with a disposable plastic cap that acts as a shield between the nozzle and the skin to eliminate cross-contamination between injections while maintaining a high rate of vaccine delivery to multiple patients.
The objective of this pilot safety study is to provide a preliminary indication of the ability of the jet injector to prevent cross-contamination from hepatitis B virus between volunteer injections. A secondary objective of the study is to test study procedures prior to a larger-scale safety study.

Diseases of viral origin, characterized by incubation periods of months to years, insidious onset of clinical manifestations, and protracted clinical course. Though the disease process is protracted, viral multiplication may not be unusually slow. Conventional viruses produce slow virus diseases such as SUBACUTE SCLEROSING PANENCEPHALITIS, progressive multifocal leukoencephalopathy (LEUKOENCEPHALOPATHY, PROGRESSIVE MULTIFOCAL), and AIDS. Diseases produced by unconventional agents were originally considered part of this group. They are now called PRION DISEASES.
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
A general term for diseases produced by viruses.
Virus diseases caused by the Lentivirus genus. They are multi-organ diseases characterized by long incubation periods and persistent infection.
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).
