Activating vaccine technology has lagged behind. Is MRNA technology advanced technology?The National Health and Health Commission responded to

On July 23, the State Council's joint prevention and control mechanism held a press conference to introduce the relevant situation of the safety effectiveness of the vaccine of the new coronary virus. At the meeting, some reporters mentioned that among the new crown virus vaccines currently vaccinated in China, the vast majority of activity vaccines accounted for, while many foreign countries used MRNA vaccines on a large scale. Some views believe that the technologies of the vaccine have lagged behind, and MRNA technology is advanced technology. In response, Zheng Zhongwei, director of the Science and Technology Development Center of the National Health and Health Commission and the leader of the research and development of the research and development of the scientific research group, clearly stated that the active vaccine is not a backward technology, but a mature classic technology.

According to reports, at present, spinal ashgone vaccines, hepatitis A vaccine, influenza vaccine, rabies vaccine, hand, foot and mouth vaccine, which are widely used worldwide, are all surviving vaccines. This time, the research and development and production of the new crown virus vaccine has many technological innovation and process improvement.

Zheng Zhongwei said that MRNA vaccine technology rose in the 1990s. It was first used to develop tumor treatment vaccines. No products were approved to be listed before the new crown epidemic. The large -scale use of MRNA vaccine is the first time in human history. Therefore, MRNA vaccine technology can be called new technology. Activating vaccines and MRNA vaccines have their own characteristics, and they must not be simply distinguished by advanced or backward.

Why do many developed countries have not developed an exciting vaccine for the first time? Zheng Zhongwei explained that this is because the active vaccine involves a large number of live virus operations. It is necessary to build a high -grade biological safety production workshop in large -scale cultivation and purifying new crown viruses in a short period of time. It is difficult to determine whether high investment can get expected benefits at the beginning of the epidemic. Thanks to my country's institutional advantages, the country in the early days of the epidemic insisted on not being lucky, regardless of gains and losses. Many departments and governments cooperated to formulate the relevant norms on the construction of the new crown virus in the production workshop of the new coronary virus, and the most at the most at the most. The fast speed has simultaneously carried out the research and development and production workshop construction of new crown virus vaccines, ensuring the need for the large -scale production of the new crown virus in the new crown virus.

Zheng Zhongwei said that in fact, foreign countries have been carrying out the development of new crown virus vaccines, but the progress is slower than our country. For example, a new crown vaccine produced in India was also included in an emergency use list by the World Health Organization at the end of last year. use. Activated vaccines developed by Turkey, Kazakhstan, Russia and other countries are also being put into use. These situations fully show that activating vaccine technology is still a global recognized mature classic technology.
