Why COVID-19 vaccination?

The introduction of Pfizer vaccine is to choose the best vaccine that is most beneficial to our health. I believe that people with a little common sense know that each vaccine has different ingredients and different effects on human cells. Introduction of vaccine: on the one hand, its components can be extracted for research. After all, our domestic medical technology still needs to learn from other countries, which is for the sake of our health. On the other hand, it is also to strengthen friendly cooperation between countries.

Although we usually have two shots of vaccine in China, most of them are Kexing vaccines, all of which are inactivated vaccines, that is, the virus is killed by high temperature or chemical methods, and then the dead virus is injected into the human body, which makes people produce antibodies for a long time.

The third injection is the recombinant protein vaccine MRNA vaccine to be injected. The first two needles are aimed at mild patients with good protection rate, which is similar to domestic and imported ones, and the third needle is aimed at severe protection. In particular, Pfizer publicizes that its vaccine prevention and protection rate can reach more than 90%, while in China it is only about 70%.

This is why there are so many COVID-19 patients in the United States, but the mortality rate has dropped, and Pfizer has played a certain role. Therefore, in February, the state announced the introduction of Pfizer and brought it into the scope of medical insurance, which was also responsible for the lives of ordinary people.

Since Pfizer was developed, there has been a great controversy about it, questioning its efficacy and side effects. However, it has an unquestionable and remarkable feature, that is, this specific drug can quickly remove COVID-19 from the body. Taking it within three days can reduce the risk of hospitalization and death by 89%, and taking it within five days can reduce the risk by 88%. To a certain extent, it reduces the use of medical resources, reduces the medical burden and reduces the pressure on isolation wards. Although it's a bit expensive, 2300 yuan a box, but if you have COVID-19, 2300 yuan can buy a life, which is also worth it.
