Korean Universities Develop Novel KE-VAC Vaccine Platform

SEOUL, South Korea (April 9, 2025) — Researchers from‍ Chungnam National University, the Korea Virus Basic Research Institute, and⁣ Sungkyunkwan University have ⁣jointly announced the development of a next-generation vaccine platform ⁣called KE-VAC (Kinetically Engineered Vaccine). This innovative platform is designed ⁢to stimulate the immune system in a manner ⁢similar⁤ to natural infections,perhaps leading to a ⁤more robust and long-lasting immune response against a variety of viruses and their variants.

KE-VAC: Mimicking Natural Infection for Enhanced Immunity

The findings of this collaborative⁤ research ‍effort were published online March 25⁣ in Nature Communications, a peer-reviewed scientific journal.

Key researchers ‍involved in the⁤ study include Professor lee Jong-soo from Chungnam National University’s ⁣Veterinary College, with DK Haluwana listed as co-first author; Professor Yong-taek Team from Sungkyunkwan University; and ‍the ‍director of the Korea Basic Research Institute.

How KE-VAC Works

The KE-VAC platform utilizes nanoparticles ⁤to‍ control the toll-receptor 7/8 agonist (TLR7/8‍ agonist), ⁢mimicking viral genetic material to⁢ gradually activate cells. This approach is coupled with aluminum-based ⁣adjuvants that slowly release antigens. The combined⁣ effect‍ ensures that the antigen ⁢and‍ immune reinforcements work synergistically,addressing the limitations⁢ of existing vaccines,such as short-term ⁣immune sustainability ⁣and immune‍ cell fatigue.

Preclinical Testing Shows Promise

In preclinical trials, the research team tested KE-VAC ⁢in mice and ferret⁤ models‍ to assess its⁣ effectiveness against various pathogens, ⁤including variants of the virus that causes COVID-19, influenza viruses, and the severe fever ⁣with thrombocytopenia syndrome ⁤(SFTS) virus. The results indicated a ⁤specific cytoplasmic immune response, suggesting broad applicability.

Potential Impact on ⁣Public health

Researchers believe that ⁢KE-VAC’s immune-stimulating mechanism represents an advancement over ⁢existing⁢ mRNA ‍vaccines and aluminum-based vaccines. They anticipate that this new platform ⁤could substantially contribute to⁣ infectious disease prevention and public health by‍ offering a⁣ novel⁢ approach to vaccine technology. Future clinical trials are planned to‍ evaluate the potential for human application.

Researcher’s Viewpoint

According to Professor Lee Jong-soo of⁢ Chungnam⁤ National University, KE-VAC creates “a more flexible and strong immune system through a multi-dimensional stimulus that ⁤mimics natural infections beyond the limitations of existing vaccines⁢ focused on short-term immunity.”

Funding

The research received support from the Support Project of the⁤ Basic⁤ Science⁤ Research Institute, the‍ Korea Research Foundation’s mid-sized researcher support‍ project, and the university-focused‍ research⁣ institute support ⁢project.
