Recently, a "light vaccine" disinfection equipment has frequently appeared in the circle of friends in the industry. When the UV LED wind direction checked relevant information, it was found that this product was developed by Columbia University, Fudan University, Shanghai Institute of Major Infectious Diseases and Biosafety. Co-developed by Interstellar (Shanghai) Industrial Co., Ltd., it uses the 222nm ultraviolet wavelength. After the "photovaccine" device is turned on, it claims to emit pure 222nm wavelength light that is harmless to the human body, and disinfects the air and the surface of the object.
This "light vaccine" equipment played a certain role in protecting the Chinese Olympic delegation from the new crown virus during the Tokyo Olympic Games. 777 people had no new crown cases and all went home safely, achieving the "zero infection" set by the delegation before the expedition. "Target.
It is understood that the entire Olympic delegation used more than 200 UV disinfection equipment. During the Olympic Games, the China House for athletes’ rehabilitation and training and every Chinese athlete’s room in the Olympic Village will be equipped with “light vaccine” equipment. , Continue to kill pathogens in the air and environment, greatly improving biological safety. The "light vaccine" is not dazzling when used, and its disinfection factor 222nm is invisible light. The human body has no perception when used, and does not affect the daily life and training of athletes.

"Light vaccine" is flexibly arranged in the corridor of the Chinese team
In 2018, Professor David Brenner of the Nuclear Medicine Research Center of the School of Public Health of Columbia University found that 222-nanometer ultraviolet light is not only harmless to the human body and effective disinfection, and published a related paper in the journal Nature .
Wu Fan, deputy dean of the Shanghai Medical College of Fudan University and dean of the Shanghai Institute of Major Infectious Diseases and Biosafety, introduced: “The light with a wavelength of 222 nanometers is suitable for scenes with people. Special places such as hospitals and nursing homes can particularly reflect their advantages.
"Light vaccine" is widely cited in the national team's rehabilitation training base
In addition to the Tokyo Olympics and Zhengzhou's anti-disaster and epidemic prevention campaign, the "light vaccine" also played a role in major hospitals and was well received by medical staff. At present, the traditional ultraviolet light disinfection used in medical institutions can only be carried out after personnel leave, but this technology can be used continuously in high-risk places such as fever clinics. After being caught fire by the Olympic delegation, the 222nm wavelength ultraviolet disinfection equipment is expected to have application prospects in transportation hubs and commercial places in the future.
