After the outbreak of the new crown pneumonia, my country has rapidly deployed multiple technical routes to develop vaccines. At present, 5 vaccines have been approved for conditional marketing or emergency use, including 3 inactivated vaccines , 1 adenovirus vector vaccine and 1 recombinant protein vaccine. At the moment, my country is speeding up the new crown virus vaccination work. The public is very concerned about the safety and effectiveness of the new crown virus vaccine, and the reporter interviewed relevant experts for this.
Wang Junzhi, academician of the Chinese Academy of Engineering, introduced that the composition of the inactivated vaccine is the closest to the natural virus structure , which is relatively stable, convenient to transport, and usually has a strong immune response. Generally, two-dose immunization is used, which has good safety. The preparation process of
adenovirus vector vaccine is relatively simple and low in cost. It was successfully developed on the basis of my country's original type 5 adenovirus Ebola vaccine. The vaccine not only effectively induces the production of neutralizing antibodies, but also enhances cellular immunity . The immunization program adopted is a one-shot immunization, which is very convenient for emergency use for some special populations.
recombinant vaccine expresses and purifies pathogen antigen proteins in engineered cells through genetic engineering, and then prepares them into vaccines. The new coronavirus vaccine developed as a new technical route is also safe.
According to reports, my country’s new coronavirus vaccine is highly accessible and safe. Citizens who are willing to vaccinate can achieve vaccination. Under the premise that the safety of domestic vaccines is guaranteed, the public is advised to actively vaccinate domestic vaccines. One's own immunity and protection.
"From the perspective of the effect of vaccine use, the new coronavirus vaccines currently used in my country have been clinically studied in accordance with the specifications, have been approved by the national drug regulatory department, and have passed the strict verification before they can be used." National Health and Health Li Bin, deputy director of the committee, said that during the storage and transportation of the vaccine, it is required to test and record the temperature regularly to ensure that the new coronavirus vaccine is in a safe environment during the whole process of storage and transportation."During the vaccination process, we have increased personnel training, requiring medical staff to strictly implement the operating procedures of'three checks, seven to one verification', and fully guarantee the effectiveness and safety of the vaccine through standardized operations. With the new coronavirus vaccination With the full implementation of the work, the number of people being vaccinated continues to increase, and I believe that the effects of vaccine use will further manifest."
