Recently, according to big data models, first- and second-tier cities have basically passed the peak of infection. Experts say that herd immunity will be achieved to a certain extent, but if new mutant strains appear, it may break through the immune barrier .
In other words, if no new mutations emerge, herd immunity will be achieved. Back then, we laughed at the British for herd immunity, but in fact, this stuff was really science.
Of course, it is not ruled out that there will be new variants after , Omicron, and in the future, but even if there are variants, the antibodies we currently produce after infection will have a certain immune effect, and the symptoms will be milder.
In fact, Europe and the United States have almost achieved herd immunity. For example, the number of infected people in the United States is almost 70%, and even the official data is still at 30%. And the number of daily infections in the United States has dropped significantly. This is the result of herd immunity.
After we relaxed the epidemic, the number of infections increased very quickly. Basically, in one month, it reached the level of Europe, the United States and Japan in three years. This was also caused by the fact that we did not form an immune barrier.
and others form an immune barrier. The virus will not disappear, but the speed of infection will slow down. Even if infects a second time, the symptoms will be milder, and the probability of third or fourth infection will become smaller and smaller.
