China News Service, September 7th, on the 7th, the State Council’s Joint Prevention and Control Mechanism held a press conference to introduce the situation regarding further efforts in epidemic prevention and control and vaccination.
Zheng Zhongwei, head of the Vaccine R&D Special Class Working Group of the Scientific Research Group and Director of the Science and Technology Development Center of the National Health Commission, said at the meeting that the sequential immunization research of vaccines with different technical routes must be carried out under the two principles of compliance with laws and regulations and respect for science. .

At the meeting, a reporter asked: It was stated at the press conference that high-risk groups can be vaccinated with the third shot. How will this work be carried out? Will it consider adopting a sequential immunization strategy?
In this regard, Zheng Zhongwei said that with the rebound of the global epidemic, strengthening immunization is currently receiving more and more attention.
However, enhanced immunization is a serious scientific issue, and implementation of enhanced immunization must also comply with the requirements of relevant laws and regulations.
The vaccine research and development class organized an expert demonstration meeting on August 2. After listening to Sinopharm Zhongsheng and Beijing Kexing Zhongwei, two companies reported on the safety and immunity of boosted immunization 6 months after two doses of inactivated vaccines. After the original data, the expert group made recommendations for boosting the original inactivated vaccine for key populations based on the above scientific data.
Zheng Zhongwei pointed out that in addition to inactivated vaccines, other technical routes of vaccines in my country have also carried out relevant research on booster immunization.
After the R&D unit obtains sufficient scientific data, experts will also be organized to carry out relevant demonstration work.
As for the sequential immunization research of vaccines with different technical routes, it must also be carried out under the two principles of compliance with laws and regulations and respect for science.
At the expert demonstration meeting on August 2, the experts clearly recommended support for sequential immunization research and pilot work.
At present, some research and development institutions in my country are also carrying out related sequential immunization research work at home and abroad. Only after obtaining sufficient scientific data on safety and immunogenicity or effectiveness, can sequential immunization of large-scale populations be possible. Work to make expert recommendations.
