cho is Sinovac. There are five types of vaccines currently available in my country that can be vaccinated, namely Beijing Biotech, Wuhan Biotech, Beijing Sinovac and Zhifei Biotech. The cho cell COVID-19 vaccine is actually a recombinant protein vaccine that expresses the most effective antigen components in cells in vitro through genetic engineering. This production process does not involve live viruses and is a protein expression and purification process. process.
Safety of the vaccine
Judging from the use process and preliminary experimental results of the protein vaccine, the safety of the recombinant protein vaccine can be guaranteed, and the adverse reaction rate is relatively low, so this kind of protein vaccine was chosen. The number of people vaccinated currently also seems to be the largest.
The CHO cell COVID-19 vaccine needs to be refrigerated at 2 to 8 degrees Celsius, and requires two to three injections of immunity with low requirements for transportation and storage conditions. The recombinant COVID-19 vaccine (CHO cells) currently on the market was jointly developed by the Chinese Academy of Sciences and enterprises. Its effectiveness is as high as 97%, and this type of vaccine is suitable for people over 18 years old, including the elderly, and its safety can be fully guaranteed.
