Title: Innovations of Yo Han Jang in Influenza Vaccine Development

Introduction

Yo Han Jang is a prominent inventor based in Goyang, South Korea. He has made significant contributions to the field of vaccine development, particularly in creating innovative solutions for influenza prevention. With a total of 2 patents, his work focuses on enhancing the efficacy and safety of influenza vaccines.

Latest Patents

One of his latest patents is a universal influenza vaccine using a cold-adapted live-attenuated virus. This vaccine composition is designed to exhibit a cross-protective effect against a wide range of influenza viruses. It ensures strong protection efficacy, a broad range of protection, and safety. The vaccination method of heterologous live vaccines induces various immunological effects, significantly increasing cross-immunogenicity and cross-protective ability. This innovation is expected to be a valuable method for universal influenza prevention.

Another notable patent involves a method of preparing live viral vaccines through genetic engineering of the viral genome. This patent discloses an attenuation method for an influenza virus, specifically a reassortant virus. The reassortant virus comprises genes encoding a recombinant non-toxic protein and a wild-type non-toxic protein, along with genes encoding toxic proteins, HA (hemagglutinin) and NA (neuraminidase). This method demonstrates high attenuation without reducing productivity in fertilized eggs, making it an economically efficient live vaccine preparation method.
