Vaccine Science Lab
Machine-translated · View original
The lab uncovers how vaccines drive the immune system and develops new vaccines.

AboutAbout the lab
Exploring the science of vaccines
The Vaccine Science Lab studies how vaccines activate the body's immune system.
The lab investigates how the immune system recognizes nucleic acids (DNA and RNA) derived from pathogens and the body's own cells, and what responses they trigger.
Using this knowledge, the lab works on developing nucleic acid-based vaccines, adjuvants, and immunotherapies.
The lab aims to provide an environment where students can learn broadly, from basic immunology research to practical vaccine development.
Key terms
- Adjuvant
- A substance added to a vaccine to strengthen the immune response
- Nucleic acid
- A molecule, such as DNA or RNA, that carries genetic information
- Innate immunity
- An immune mechanism that the body naturally has, which responds immediately to invading pathogens

ResearchResearch themes
The lab studies how nucleic acids regulate immunity, and what that regulation means, in infectious diseases and other immune-related diseases. It develops nucleic acid-based vaccines, adjuvants, and immunotherapies, with the aim of realizing "Bench to Clinic."
*Illustrative imageHow vaccines drive the immune system
Vaccines are one of the most successful medical technologies, yet their molecular mechanisms remain unclear. The lab aims to clarify, at the molecular level, how vaccines and adjuvants transmit signals inside cells and between cells through innate immune receptors.
*Illustrative imageDeveloping next-generation adjuvants
Depending on how they are used, adjuvants can be either poison or medicine. To bring out their benefits while suppressing side effects, the lab develops adjuvants that use nucleic acids such as DNA and RNA, as well as adjuvants that combine these with technologies for delivering them to targeted tissues and cells.
