h5n1 whole virus influenza vaccine

The **H5N1 whole virus influenza vaccine** is an inactivated or killed vaccine derived from the entire H5N1 (avian/bird flu) influenza virus. Unlike subunit or split-virus vaccines, it contains the complete virion, ensuring presentation of all viral antigens to the immune system. This vaccine is designed for active immunization against influenza A virus H5N1 subtype, which poses a pandemic threat due to its potential for high mortality and limited human immunity[6]. Whole virus vaccines typically induce robust antibody and T-cell responses owing to their antigenic breadth. They are produced by culturing the virus (often in eggs or cell lines), followed by inactivation; the resultant vaccine may include an adjuvant to enhance immune response. These vaccines are intended primarily for pandemic preparedness and stockpiling rather than routine commercial availability[4][6]. They may be deployed if H5N1 strains gain capability for efficient human-to-human transmission or during an outbreak among high-risk populations[6].
