Wang Huaqing: New crown vaccine research and development is difficult, and monitoring after successful research and development is more important

"Everyone says that it is difficult to develop vaccines.

Wang Huaqing mentioned that monitoring includes two stages, one is the clinical trial stage, and the other is the post-marketing stage of the vaccine.

Regarding the monitoring of clinical trials, Wang Huaqing mentioned for example that in the process of making vaccines, monitoring of infection, disease, severe illness, death and other indicators is the prerequisite for evaluating the effectiveness of a vaccine.

"When selecting countries for clinical trials, if the monitoring capabilities are not strong, the results obtained may be different.

Regarding the monitoring of the vaccine in the post-marketing stage, Wang Huaqing mentioned that vaccination is no longer a problem, but the monitoring may still face some challenges.

Wang Huaqing mentioned that some foreign vaccines have found adverse events related to thrombosis.

Wang Huaqing said that in addition to the importance of monitoring, the research and development and application of the new crown vaccine have also brought many enlightenments, such as the importance of basic research, the rapid advancement of new technologies, technical production process reserves, green channels for regulatory agencies, and rapid global information sharing.
