Regarding vaccinations for people over 60 years of age, some areas have begun to vaccinate new crown vaccines for people over 60 years of age who have better physical conditions under the premise of fully assessing their health conditions and the risk of infection.
At the same time, vaccine research and development units are also accelerating research and development. After clinical trials have obtained sufficient safety and effectiveness data, we will carry out large-scale vaccination for the elderly over 60 years old.

In the early stage of this new crown vaccine, whether it is the results of clinical trial research, emergency use research results, or the results of post-marketing surveillance, its adverse reactions are similar to those of the same types of marketed vaccines that have been used in the past. , There is no abnormal situation.
The adverse reactions we monitor now mainly include local reactions and systemic reactions.
The local reaction is mainly because it is a vaccination, there will be pain after vaccination, some will appear red and swollen, some will appear induration, but these local reactions generally do not need to be dealt with and will heal by themselves; systemic reactions are now mainly There are relatively many manifestations, one is headache, fatigue, and some will have low fever. This is the result of our current monitoring.

According to the evaluation results of the vaccines currently used abroad after the market, it also confirms that a small number of people have failed to protect after the vaccine. So I think, regarding the protective effect of the vaccine, it protects most of them. It is a serious illness. For individual people, protection failure may occur due to individual reasons, of course, there are other reasons. In fact, we will continue to study the reasons for his failure and also conduct investigations.
