As we all know, we are now trying to live in a special period. Many people have suffered some injuries because of this special period, and their lives have not been very good. Many people have a certain degree. During the period of injury, there are also many people who have bad jobs because of this incident, and there are also many people who have made themselves in bad physical condition. Many people want to solve these problems better through the development of science and technology as soon as possible. We are all speeding up the development of COVID-19 vaccine, and many enterprises hope to have better technology to develop it, because it is really a special situation now. The protective efficacy of COVID-19 vaccine was 79.34%. What is the significance of this data? I think there are three main meanings:

First of all, this means that COVID-19's vaccine research and development is relatively successful. In fact, many enterprises want to develop COVID-19 vaccine, because COVID-19 vaccine is really in urgent need and should be developed. Because if we don't develop, it is very likely that our special situation will not get better will, and it may expand, affecting the global economic development and the whole society. These data show that COVID-19 vaccine has actually been developed successfully.

Secondly, it means that most COVID-19 vaccines are relatively easy to use. I think this data accounts for a large part of the success rate, which just shows that COVID-19 vaccine is also relatively easy to use, which can be better applied to practice and can also play a better role.

Finally, this means that the efficacy of COVID-19 vaccine is relatively high. I think this can show that the efficacy of COVID-19 vaccine is still relatively high, and it can play a certain role, and it can also make us in COVID-19 have a better will, which can better promote us to solve this disease.

All in all, I think this is very meaningful.
