Safety data released for more than 500,000 vaccinations of Sinopharm China's new bio-new crown inactivated vaccine

At present, the new crown vaccination campaign has been widely launched in China.

The new crown inactivated vaccine developed by the Wuhan Institute of Biological Products and Beijing Institute of Biological Products under Sinopharm China Biotechnology Co.

Two new inactivated vaccines developed by the Wuhan Institute of Biology and Beijing were approved to be included in the emergency use of China's new crown vaccine in June and July 2020.

The overall adverse reaction rate is low, and no serious adverse reactions have been found

The system monitored a total of 519,543 vaccination information and found 5164 pieces of adverse reaction information.

Some discussion

During the discussion of the paper, the researchers pointed out that the safety data obtained during this emergency use process was significantly better than the safety results of the inactivated vaccine in the phase 2 clinical trial.

The types of adverse reactions found in this study are similar to those in clinical trials, and compared with other types of inactivated vaccines, the adverse reaction rate of the new coronavirus inactivated vaccine is also relatively low.

The author pointed out at the end of the paper that increasing the vaccination rate and gradually establishing herd immunity is one of the most effective ways to stop the spread of the new crown epidemic.
