On the morning of April 24, at the 2021 Frontiers Forum of Medical Science of the Chinese Academy of Engineering held in Guangzhou, Academician Zhong Nanshan gave an online report. He pointed out that he is currently working hard to develop a vaccine against mutant strains of the new coronavirus.

When talking about the precise prevention of the new crown epidemic, Zhong Nanshan said that the main contradiction we currently encounter is the mutation of the new crown virus. The mutant strains currently appearing are from the United Kingdom, Brazil, Nigeria, South Africa and other places. Now it seems that for the b1351 mutant strain in South Africa, we use a whole virus inactivated vaccine, which is the most commonly used vaccine of Kexinghe Sinopharm in China, and the protection rate against this mutant strain has been reduced. Now we are working hard to develop vaccines against mutant strains.

Academician Zhong Nanshan introduced that there are currently nearly 50 vaccines in the development process in China, and more than 200 vaccines are being developed in the world.

IT Home learned that the current national vaccination work is progressing smoothly. Up to now, my country's new crown vaccination has exceeded 200 million doses.

According to the rules, the experts will vote for the final review, and the online voting and the expert voting of the review committee will be weighted 1:1, and the order of the top three will be finally determined. The top three orders determined by the final review will be submitted to the National Space Administration for approval in accordance with procedures to determine the final name of China's first Mars rover.

The increase in China's defense expenditure is not only a need to maintain its own security, but also a need to maintain world peace. Continuing to maintain a moderate and steady increase in defense spending is justified, reasonable and beyond reproach.

In an interview with the media on the 7th, Wu Qian, spokesperson for the PLA and Armed Police Force delegation at the Fourth Session of the 13th National People’s Congress, said that China’s defense expenditure will continue to maintain a moderate and steady growth in 2021, an increase of 6.8% over the previous year.

A reporter asked that the Chinese economy was the first to emerge from the shadow of the new crown pneumonia epidemic and achieve positive growth last year. How will the defense budget for this year be arranged?

Wu Qian said that 2020 is an extraordinary year in the history of New China. Facing the severe impact of the new crown pneumonia epidemic, under the strong leadership of the Party Central Committee with Comrade Xi Jinping at the core, under the joint efforts of the people of all ethnic groups across the country , The fight against the new crown pneumonia epidemic has achieved major strategic results, and my country's economy has achieved positive growth.

Wu Qian said that the Chinese government adheres to the principle of coordinated development of national defense and economic construction, and reasonably determines the scale of defense expenditures. In recent years, in order to safeguard national sovereignty, security, and development interests, adapt to the needs of military reforms with Chinese characteristics, and better fulfill the international responsibilities of major powers, the Chinese government has maintained a reasonable and stable growth in defense expenditures and promoted national defense while sustained and healthy economic and social development. Strength and economic strength have increased simultaneously.

Wu Qian said that in 2021, the national budget for national defense expenditures will be 1,379.544 billion yuan (including 1,355,343 million yuan allocated by the central government), an increase of 6.8% over the previous year’s budget implementation. The increased defense expenditure is mainly used in the following aspects: first, to ensure the implementation of major projects and key projects in accordance with the "14th Five-Year Plan" plan for army building; second, to accelerate the upgrading of weapons and equipment, and to promote the modernization of weapons and equipment; Accelerate the transformation of military training, build a new military talent training system, and improve and perfect training guarantee conditions; fourth, to adapt to the country's economic and social development level, improve the life and welfare of officers and soldiers, and serve the grassroots construction of the army.

Wu Qian said that a strong country must have a strong army, and a strong army can lead to national security. National defense is as important as sunlight and air, benefiting without realizing it, losing it is hard to survive. At present, the instability and uncertainty facing international security have become more prominent. The new crown pneumonia epidemic is raging around the world, hegemonism, power politics, and unilateralism are on the rise from time to time, regional conflicts and local wars continue, and the international security system and order are under attack. The risks and challenges facing my country’s homeland security cannot be ignored. Land border disputes have not yet been completely resolved, island territorial issues and maritime delimitation disputes still exist; the DPP authorities stubbornly adhere to the separatist stand of "Taiwan independence", which is the biggest real threat to peace and stability across the Taiwan Strait. In view of the current complex situation, it can be said that the world is not peaceful, and national defense must be strong.

Wu Qian said that at the same time, the international community has more expectations for the Chinese military to provide public security products. In recent years, our military has actively participated in UN peacekeeping operations, normalized naval escorts, and carried out humanitarian relief operations, and has won wide acclaim from the international community. Especially since the outbreak of the new crown pneumonia, the Chinese military has provided support and assistance to the international community through vaccine assistance and dispatch of expert teams. History has and will continue to prove that the Chinese military has always been a staunch force for safeguarding world peace. The increase in China's defense expenditure is not only a need to maintain its own security, but also a need to maintain world peace. Continuing to maintain a moderate and steady increase in defense spending is justified, reasonable and beyond reproach.
