Overview

The **inactivated whole virion H5N1 vaccine + aluminium hydroxide** is a monovalent vaccine designed for pandemic preparedness against the H5N1 strain of avian influenza. Unlike split-virion or subunit vaccines, this formulation utilizes the entire inactivated virus particle, which preserves the full array of viral antigens and has been shown to be more immunogenic in populations that are immunologically naive to the H5 strain. The addition of **aluminium hydroxide** (alum) as an adjuvant enhances the immune response by creating a depot effect at the injection site and stimulating the recruitment of antigen-presenting cells. This specific formulation has been developed and stockpiled by several manufacturers, most notably **Sinovac** (under the brand name Panflu) in China and a consortium of manufacturers in Japan, to provide a rapid response capability in the event of an H5N1 influenza pandemic.
