Today, the new coronavirus vaccine developed by the American company Moderna announced the start of clinical trials. Many people were surprised that the American company has strong scientific and technological strength, and the vaccine can be clinical soon.


At the same time, there are a lot of doubts about the development of vaccines in the United States, because everyone knows that it takes at least a year to a year and a half to get the vaccine, and it is impossible to get it in one or two months.

Regarding this problem, some scholars pointed out that this vaccine is not new, but a nucleic acid vaccine ( mRNA-1273 ) previously developed for MERS and has been tested in animals before.

Now the reason why this vaccine can be so fast on I clinical trial, because the vaccine does not use the new crown virus samples, but minor changes in the old vaccine, 2 ends of the month to submit to the National School of Medicine, NIH to do a test.

In addition, the company ’s vaccine research and development were sponsored by the NIH, and it received special approval. It has not been tested in animals (the original version has been tested).

From this point of view, the rapid progress of the vaccine in the United States is also a special case. The vaccine does not use virus samples and skips animal tests. Now it is directly tested in humans. The safety can be guaranteed, but the effect is difficult to say.

Even if the speed of this stage is greatly improved, the subsequent clinical tests will not save time. It is reported that the phase II clinical trial will take at least several months, and the phase III clinical verification will follow.

For vaccines, especially RNA vaccines required by the new coronavirus, it takes a long time to develop an effective vaccine. Scientists from various countries recognize that time is 12-18 months. This is already a very fast speed. Count on one or two. It took months to get a vaccine, which is against the laws of science.

It is worth mentioning that after Moderna announced the clinical vaccine, the company's stock price rose 25% in the plummeting US stocks, which became a miracle in the stock market.
