Mrna vaccine allergy

Let's talk about mRNA first. This vaccine has many advantages besides high storage requirements, low cost, easy adjustment, quick response and good effect.

We also developed mRNA vaccine in China, or at the beginning, four kinds of vaccines went hand in hand. Finally, the effect is good only if the inactivation progress is caught up. However, fire-fighting vaccine has a congenital defect, that is, it can not provide corresponding changes according to virus variation like mRNA. In the case of virus transmission, it is not enough.

Why do Americans use mRNA? Because they are technologically advanced. But why are there so many abnormal reactions? Because of political pressure, there are problems in clinical phase III, but we still pay close attention to online production and force it to be promoted. This is much better in China than in the United States.

In fact, last September, domestic inactivation was successfully developed. However, due to the current vaccine standards, the third phase mainly takes a long time, and the domestic epidemic situation is too well controlled, but there are few cases, so there is no large-scale listing.

Now the United States is the first to break the industry standard, and there are problems in the third phase, so it is forced to go public on the political platform. Of course, domestic inactivated vaccines can be listed appropriately.

By the way, China also ordered 1 100 million doses of mRNA Pfizer vaccine.

By the way, some people are against China ordering American vaccines. I think this is the embodiment of our national responsibility. The disadvantage of inactivated vaccine is that it cannot be adjusted quickly according to virus variation. Nowadays, with so many infected people, it is only a matter of time before the virus mutates, such as the virus mutation with enhanced transmission found in Britain. Although the research shows that the vaccine is still effective for this mutation at present, no one can guarantee whether the virus mutation will be resistant to the vaccine in the future. Domestic inactivation is difficult to solve this situation quickly, while mRNA vaccine can solve this variation quickly. Therefore, the country ordered the mRNA Pfizer vaccine. Recognize the gap, strive to catch up, seek truth from facts and praise the motherland.

At present, the supply of vaccines is in short supply, and the vaccines ordered in China are expected to arrive at the end of 2/kloc-0 at the earliest. During this period, the first batch of people vaccinated can be said to have survived the third phase of clinical practice (usually one year), during which the adverse reactions are estimated to be fine-tuned, and Pfizer has also made vaccine adjustments for virus variation.
