Zheng Zhen: American vaccine is a good vaccine but cannot save the Chinese epidemic

At the moment when the situation of the Chinese epidemic situation is becoming increasingly severe, the United States has recently stated that they are willing to provide vaccines to China. The political struggle behind this is too grand. The most concerned of ordinary Chinese people is whether the American vaccine can save the Chinese epidemic.

From a large number of mainland tourists recently, they have made a special trip to Macau to take over the messenger ribonucleic acid (MRNA) vaccine. Many people believe that American vaccines can provide better protection.But this is just a personal choice.There are 1.4 billion people in China, and the Chinese government has not approved the US vaccine. In addition to political considerations, there are realistic problems that cannot be overcome in a short time.

In terms of cost, the storage conditions required by the Pfizer vaccine and Modner vaccine are very harsh.The Pfizer vaccine can only be stored for 5 days from 2 degrees Celsius to 8 degrees Celsius, and it can be stored for 6 months at minus 80 degrees to minus 60 degrees.Modner vaccines can be stored for 30 days from 2 degrees Celsius to 8 degrees Celsius, and can be stored for 6 months at minus 80 degrees to minus 60 degrees.

China's land depth and population determine that if the U.S. vaccine is used on a large scale, it is not realistic to temporarily build a huge free vaccine frozen facilities.The storage conditions are 2 degrees Celsius to 8 degrees Celsius under normal storage conditions of the Kangshino vaccine, national medicine vaccine, and Koxing vaccine in China. They are the same as the storage conditions of existing rabies vaccines and hepatitis A vaccine.Increase costs significantly.

China itself has also developed the MRNA vaccine. In September this year, the Chinese-made MRNA vaccine that has been urgently used in Indonesia this year can be stored at 2-8 degrees Celsius.No need to thaw.From the perspective of cost -effective, China spends more costly using the American vaccine. Of course, it is hoped that when the conditions are mature, the MRNA vaccine produced in China that does not need to increase more costs.This is a very important real issue for the development of medical resources that is not very abundant.

The US vaccine has been widely used, and many people in the medical community are considered more advanced and the protection rate is higher. It seems that the Chinese government should not abandon such superior things.In fact, it is not easy to use or not, but it is more important to be suitable.

If there is a space to choose a better vaccine, no country will retreat and choose a vaccine with low protection effect.In the past three years, the phenomenon of buying vaccines from various countries is not required, and it is not easy to grab the vaccine.The most fundamental reason for the reason why Chinese vaccines are used in Africa, Southeast Asia, and the Middle East countries are cost -effective.This is a market choice.Under the circumstances of ability, preferentially selected vaccines that can be selected, which is the basic logic.Asked why China does not use American vaccines, it is more like a fool who does not eat meat.

At the moment when the situation of the epidemic spread is based on daily calculations, China has established a basic vaccine protection barrier. What can be done is to quickly promote the vaccine penetration rate along the existing channels, rather than the stove to fight the United States vaccine.Tiffy.

China is a big country that is moving towards modernization. In its long -term historical period, a very important governance experience is not to suffer from unevenness.If it is considered to be more effective in American vaccines into the Chinese market, it is unknown whether it will trigger a social chaos that scrambles to fight.From this point of view, it is difficult to say that it is irresponsible to not introduce American vaccines.If the governance of the big country is small, whether China introduces the American vaccine, it depends on whether the timing is mature and whether the consequences are controllable.

The MRNA vaccine produced in China has been urgently authorized in Indonesia in September 2022. It has matured technically, but when it is put into use in China, it also needs to undergo more stringent approval procedures.Therefore, it is not that China does not approve the American MRNA vaccine, but that the entire Chinese society has not begun to use any MRNA vaccine.

China will not simply not approve the US vaccine for political purposes.When the Chinese MRNA vaccine can mass production, market balance and social stability can be taken into account, whether it is not approved by the US vaccine will not be a problem.

The United States is willing to provide vaccines and believes that China is willing to consider this as support, but it must also consider whether this kind of goodwill China can digest and whether there is conditions to catch it.China's population is 1.41 billion, and the US population is 330 million.If China wants to use US vaccines, can the United States supply 1.4 billion people to use the US vaccine?If there are enough vaccines, a small amount of vaccine is just an explosive bag that causes social anxiety.

It cannot be inferred that China has malice against the United States alone from the goodwill of the United States. The United States may just talk about public opinion war.
