Human Hepatitis B Immunoglobulin

Introduction

Human Hepatitis B Immunoglobulin is a special preparation of antibodies that provides protection against the Hepatitis B virus. It is mainly used for immediate protection in individuals exposed to the virus, such as newborns of infected mothers or healthcare workers after accidental exposure. This immunoglobulin helps prevent Hepatitis B infection until the Hepatitis B vaccine can start working. It is a highly effective treatment option for reducing the risk of developing the infection in high-risk cases.
