Shenzhen Hetao and the Chinese University of Hong Kong have established a joint laboratory. The laboratory was officially put into use recently. The Waiwaishu GFK antibacterial board produced by Zhejiang Aobang Technology was selected as the ceiling material after testing due to its unique flatness, sealing and negative pressure bearing performance. Since the group of people vaccinated with mRNA vaccines in Hong Kong is relatively large, while the inactivated vaccine, protein vaccine and adenovirus vaccine are more commonly vaccinated in the mainland. In order to take advantage of this difference between the two places, the laboratory will join the scientific research teams in the mainland and Hong Kong to "study the best way to make the new crown vaccine." This project is also another example of Guangdong and Hong Kong promoting in-depth cooperation in biomedicine.
