At present, the preventive effect of novel coronavirus vaccine on severe death is still clear and significant, and it is better to complete the whole course vaccination and booster vaccination of the existing vaccine.
The research on Omicron vaccine is expected to increase the means to deal with novel coronavirus in the future. Although the vaccine of Omicron mutant has entered clinical trials, it will take time to determine its research results, and there are still some uncertainties in the evolution of the virus. However, the development of the Omicron epidemic has increased uncertainty and challenges.
If we do not complete the whole process of novel coronavirus vaccination and strengthen needle vaccination as soon as possible, once the epidemic situation occurs, especially for the elderly and people with chronic basic diseases, it will bring more severe cases and increase the burden of medical treatment. The urgent task is to complete the whole vaccination as soon as possible.
