Its development is very fast, even faster than the fastest spreading ba 2. It rose by 9.8%. This means that Xe has the potential for large-scale popularization. And currently dominates the world, but because the data sample is too small, whether it will become a potential threat in the future needs further observation. After countries relaxed prevention and control, epidemic data became less and less representative.
This hinders our ability to locate, spread and evolve novel coronavirus's disease, and this information and analysis is still crucial for effectively ending the acute phase of COVID-19. COVID-19 will not disappear in the next few years. People who have been fully vaccinated later this year will need a fourth injection, the second booster injection. The protection people get from the third needle is good enough. It is very effective in reducing hospitalization rate and mortality rate, but it is ineffective in preventing infection. The mortality rate has been greatly reduced. Israel is also one of the most active countries in the world to strengthen vaccination. Most countries did not carry out the fourth booster vaccination.
The research report has not been peer-reviewed, and no one in this study has received modern vaccines or COVID-19 drugs. During the epidemic, the Israeli Ministry of Health conducted a lot of research on the efficacy of vaccines, which also influenced the decision-making of many countries, including Canada. Judging from the current situation of global epidemic control, with the continuous expansion of vaccine production capacity in novel coronavirus, the global vaccine industry in novel coronavirus is facing a situation of oversupply.
